How are they defined? Improved drinking-water sources are defined in terms of the types of technology and levels of services that are likely to provide safe water. Improved water sources include household connections, public standpipes, boreholes, protected dug wells, protected springs and rainwater collection.

Unimproved water sources are unprotected wells, unprotected springs, vendor-provided water, bottled water unless water for other uses is available from an improved source and tanker truck-provided water.

Improved sanitation facilities are defined in terms of the types of technology and levels of services that are likely to be sanitary. Improved sanitation includes connection to a public sewers, connection to septic systems, pour-flush latrines, simple pit latrines and ventilated improved pit latrines.

Service or bucket latrines from which excreta are removed manually , public latrines and open latrines are not considered to be improved sanitation. Access to safe drinking-water and improved sanitation are fundamental needs and human rights vital for the dignity and health of all people. The health and economic benefits of a safe water supply to households and individuals especially children are well documented.

Both indicators are used to monitor progress towards the Millennium Development Goals. Water, Sanitation and Hygiene. World Health Statistics, Children aged 1 y ear immunized against measles. Estimates of vaccination coverage of children aged 1 year are used to monitor vaccination services, to guide disease eradication and elimination programmes and as indicators of health system performance.

Measles vaccination coverage is defined as the percentage of 1-year-olds who have received at least one dose of measles-containing vaccine in a given year. In countries that recommend that the first dose be given to children over 12 months of age, the indicator is calculated as the proportion of children under 24 months of age receiving one dose of measles-containing vaccine.

Measles is a leading cause of vaccine-preventable childhood deaths, and unvaccinated populations are at risk for the disease. Measles is a significant infectious disease because it is so contagious that the number of people who would suffer complications after an outbreak among nonimmune people would quickly overwhelm available hospital resources.

When vaccination rates fall, the number of nonimmune persons in the community rises, and the risk for an outbreak of measles consequently rises. Millennium Development Goals indicators database. This indicator reflects the percentage of women who consumed any iron-containing supplements during the current or past pregnancy within the last 2 years. It provides information about the quality and coverage of perinatal medical services.

Daily iron and folic acid supplementation is currently recommended by WHO as part of antenatal care to reduce the risk of low birth weight, maternal anaemia and iron deficiency. However, despite its proven efficacy and wide inclusion in antenatal care programmes, its use has been limited in programme settings, possibly due to a lack of compliance, concerns about the safety of the intervention among women with an adequate iron intake, and variable availability of the supplements at community level.

This indicator is included as a process indicator in the core set of indicators for the Global Nutrition Monitoring Framework. The indicator is defined as the proportion of women who consumed any iron-containing supplements during the current or past pregnancy within the last 2 years. Data can be reported on any iron-containing supplement including iron and folic acid tablets IFA , multiple micronutrient tablets or powders, or iron-only tablets which will vary by country policy.

Improving the intake of iron and folic acid by women of reproductive age could improve pregnancy outcomes and enhance maternal and infant health. Iron and folic acid supplementation improve iron and folate status of women before and during pregnancy, in communities where food-based strategies are not yet fully implemented or effective. Folic acid supplementation with or without iron provided before pregnancy and during the first trimester of pregnancy is also recommended for decreasing the risk of neural tube defects.

Anaemia during pregnancy places women at risk for poor pregnancy outcomes, including maternal mortality and also increases the risks for perinatal mortality, premature birth and low birth weight. Infants born to anaemic mothers have less than one half the normal iron reserves. Morbidity from infectious diseases is increased in iron-deficient populations, because of the adverse effect of iron deficiency on the immune system.

Iron deficiency is also associated with reduced work capacity and with reduced neurocognitive development. Demographic and Health Surveys. Global Nutrition Monitoring Framework: Operational guidance for tracking progress in meeting targets for Children with diarrhoea receiving oral rehydration therapy. This indicator is the prevalence of children with diarrhoea who received oral rehydration therapy.

It is the proportion of children aged 0—59 months who had diarrhoea and were treated with oral rehydration salts or an appropriate household solution. The terms used for diarrhoea should cover the expressions used for all forms of diarrhoea, including bloody stools consistent with dysentery and watery stools, and should encompasses mothers' definitions as well as local terms. Diarrhoeal diseases remain one of the major causes of mortality among children under 5, accounting for 1.

As oral rehydration therapy is a critical component of effective management of diarrhoea, monitoring coverage with this highly cost—effective intervention indicates progress on an intermediate outcome indicator of the Global Nutrition Targets, prevalence of diarrhoea in children under 5 years of age.

Children with diarrhoea receiving zinc. This indicator reflects the prevalence of children who were given zinc as part of treatment for acute diarrhoea. Unfortunately, there are no readily available data on this indicator, which is maintained in the NLIS to encourage countries to collect and compile data on these aspects in order to assess their national capacity.

Measures to prevent childhood diarrhoeal episodes include promoting zinc intake. Diarrhoeal diseases account for nearly 2 million deaths a year among children under 5, making them the second most-common cause of child death worldwide. The greater the prevalence of zinc supplementation during diarrhoea treatment, the better the outcome of treatment for diarrhoea. WHO and the United Nations Children's Fund UNICEF recommend exclusive breastfeeding, vitamin A supplementation, improved hygiene, better access to cleaner sources of drinking-water and sanitation facilities and vaccination against rotavirus in the clinical management of acute diarrhoea and also the use of zinc, which is safe and effective.

Specifically, zinc supplements given during an episode of acute diarrhoea reduce the duration and severity of the episode, and giving zinc supplements for days lowers the incidence of diarrhoea in the following months. Currently no data are available. The impact of zinc supplementation on childhood mortality and severe morbidity. Report of a workshop to review the results of three large studies. Geneva , World Health Organization, Children aged months receiving v itamin A supplements.

These indicators are the proportion of children aged months who received one and two doses of vitamin A supplements, respectively. The indicators are defined as the proportion of children aged months who received one or two high doses of vitamin A supplements within 1 year. Current international recommendations call for high-dose vitamin A supplementation every months for all children between the ages of 6 and 59 months living in affected areas.

The recommended doses are IU for month-old children and IU for those aged months. Programmes to control vitamin A deficiency enhance children's chances of survival, reduce the severity of childhood illnesses, ease the strain on health systems and hospitals and contribute to the well-being of children, their families and communities.

The World Summit for Children set the goal of virtual elimination of vitamin A deficiency and its consequences, including blindness, by the year The critical role of vitamin A for child health and immune function also makes control of deficiency a primary component of efforts to improve child survival and therefore of the achievement of the fourth Millennium Development Goal, a two-thirds reduction in mortality of children under 5 by the year As there is strong evidence that supplementation with vitamin A reduces child mortality, measuring the proportion of children who have received vitamin A within the past 6 months can be used to monitor coverage with interventions for achieving the child survival-related Millennium Development Goals.

Supplementation with vitamin A is a safe, cost-effective, efficient means for eliminating its deficiency and improving child survival.

Immunization, Vaccines and Biologicals. These indicators are the proportion of children aged months who received one or two doses of vitamin A supplements. The indicator reflects the proportion of babies born in facilities that have been designated as Baby-friendly. Proportion of births in Baby-friendly facilities is included as a process indicator in the core set of indicators for the Global Nutrition Monitoring Framework. This indicator is defined as the proportion of babies born in facilities designated as Baby-friendly in a calendar year.

To be counted as currently Baby-friendly, the facility must have been designated within the last five years or been reassessed within that timeframe. Facilities may be designed as Baby-friendly if they meet the minimum Global Criteria, which includes adherence to the Ten Steps for Successful Breastfeeding and the International Code of Marketing of Breast-milk Substitutes. The Ten steps include having a breastfeeding policy that is routinely communicated to staff, having staff trained on policy implementation, informing pregnant women on the benefits and management of breastfeeding, promoting early initiation of breastfeeding, among others.

The International Code of Marketing of Breast-milk Substitutes restricts the distribution of free infant formula and promotional materials from infant formula companies. The more of the Steps that the mother experiences, the better her success with breastfeeding. Improved breastfeeding practices worldwide could save the lives of over children every year. National implementation of the Baby-friendly Hospital Initiative.

Implementation of the Baby-friendly Hospital Initiative. Mothers of children months receiving counselling, support or messages on optimal breastfeeding. Breastfeeding is an unequalled way of providing ideal food for the healthy growth and development of infants; it is also an integral part of the reproductive process with important implications for the health of mothers.

Optimal practices include early initiation of breastfeeding within 1 hour, exclusive breastfeeding for 6 months followed by appropriate complementary with continued breastfeeding for 2 years or beyond.

Even though it is a natural act, breastfeeding is also a learned behaviour. Virtually all mothers can breastfeed provided they have accurate information, and support within their families and communities and from the health care system.

This indicator has been established to measure the proportion of mothers receiving breastfeeding counselling, support or messages. The proportion of mothers of children months who have received counselling, support or messages on optimal breastfeeding at least once in the previous 12 months is included as a process indicator in the core set of indicators for the Global Nutrition Monitoring Framework.

The indicator gives the percentage of mothers of children aged months who have received counselling, support or messages on optimal breastfeeding at least once in the last year. Counseling and informational support on optimal breastfeeding practices for mothers has been demonstrated to improve initiation and duration of breastfeeding, which in has many health benefits for both the mother and infant.

Breast milk contains all the nutrients an infant needs in the first six months of life. Breastfeeding protects against diarrhoea and common childhood illnesses such as pneumonia, and may also have longer-term health benefits for the mother and child, such as reducing the risk of overweight and obesity in childhood and adolescence. Breastfeeding has also been associated with higher intelligence quotient IQ in children.

Salt iodization has been adopted as the main strategy for eliminating iodine-deficiency disorders as a public health problem, and the aim is to achieve universal salt iodization. While other foodstuffs can be iodized, salt has the advantage of being widely consumed and inexpensive. Salt has been iodized routinely in some industrialized countries since the s.

This indicator is a measure of whether a fortification programme is reaching the target population adequately. The indicator is a measure of the percentage of households consuming iodized salt, defined as salt containing parts per million of iodine. Iodine deficiency is most commonly and visibly associated with thyroid problems e. Consumption of iodized salt increased in the developing world during the past decade: This means that about 84 million newborns are now being protected from learning disabilities due to iodine-deficiency disorders.

Monitoring the situation of women and children. Sustainable elimination of iodine deficiency disorders by Micronutrient deficiencies, iodine deficiency disorders. Population with less than the minimum dietary energy consumption.

This indicator is the percentage of the population whose food intake falls below the minimum level of dietary energy requirements, and who therefore are undernourished or food-deprived. The estimates of the Food and Agriculture Organization of the United Nations FAO of the prevalence of undernourishment are essentially measures of food deprivation based on calculations of three parameters for each country: The average amount of food available for human consumption is derived from national 'food balance sheets' compiled by FAO each year, which show how much of each food commodity a country produces, imports and withdraws from stocks for other, non-food purposes.

FAO then divides the energy equivalent of all the food available for human consumption by the total population, to derive average daily energy consumption. Data from household surveys are used to derive a coefficient of variation to account for the degree of inequality in access to food. Similarly, because a large adult needs almost twice as much dietary energy as a 3-year-old child, the minimum energy requirement per person in each country is based on age, gender and body sizes in that country.

The average energy requirement is the amount of food energy needed to balance energy expenditure in order to maintain body weight, body composition and levels of necessary and desirable physical activity consistent with long-term good health. It includes the energy needed for the optimal growth and development of children, for the deposition of tissues during pregnancy and for the secretion of milk during lactation consistent with the good health of the mother and child.

The recommended level of dietary energy intake for a population group is the mean energy requirement of the healthy, well-nourished individuals who constitute that group. FAO reports the proportion of the population whose daily food intake falls below that minimum energy requirement as 'undernourished'.

Trends in undernourishment are due mainly to: The indicator is a measure of an important aspect of food insecurity in a population. Sustainable development requires a concerted effort to reduce poverty, including solutions to hunger and malnutrition. Alleviating hunger is a prerequisite for sustainable poverty reduction, as undernourishment seriously affects labour productivity and earning capacity.

Malnutrition can be the outcome of a range of circumstances. In order for poverty reduction strategies to be effective, they must address food access, availability and safety. Rome, October The State of Food Insecurity in the World Economic growth is necessary but not sufficient to accelerate reduction of hunger and malnutrition.

FAO methodology to estimate the prevalence of undernourishment. FAO, Rome, 9 October Infant and young child feeding. The recommendations for feeding infants and young children 6—23 months include: The caring practice indicators for infant and young child feeding available on the NLIS country profiles include: Early initiation of breastfeeding.

This indicator is the percentage of infants who are put to the breast within 1 hour of birth. Breastfeeding contributes to saving children's lives, and there is evidence that delayed initiation of breastfeeding increases their risk for mortality. Infants under 6 months who are exclusively breastfed. This indicator is the percentage of infants aged 0—5 months who are exclusively breastfed.

It is the proportion of infants aged 0—5 months who are fed exclusively on breast milk and no other food or drink, including water. The infant is however, allowed to receive ORS and drops and syrups containing vitamins, minerals and medicine. Exclusive breastfeeding is an unequalled way of providing the ideal food for the healthy growth and development of infants; it is also an integral part of the reproductive process, with important implications for the health of mothers.

An expert review of evidence showed that, on a population basis, exclusive breastfeeding for 6 months is the optimal way of feeding infants. Breast milk is the natural first food for infants. It provides all the energy and nutrients that the infant needs for the first months of life. Breast milk promotes sensory and cognitive development and protects the infant against infectious and chronic diseases.

Exclusive breastfeeding reduces infant mortality due to common childhood illnesses, such as diarrhoea and pneumonia, and leads to quicker recovery from illness. Breastfeeding contributes to the health and well-being of mothers, by helping to space children, reducing their risks for ovarian and breast cancers and saving family and national resources.

It is a secure way of feeding and is safe for the environment. Infants aged 6—8 months who receive solid, semisolid or soft foods. WHO recommends starting complementary feeding at 6 months of age.

It is defined as the proportion of infants aged 6—8 months who receive solid, semisolid or soft foods. When breast milk alone no longer meets the nutritional needs of the infant, complementary foods should be added. This is a very vulnerable period, and it is the time when malnutrition often starts, contributing significantly to the high prevalence of malnutrition among children under 5 worldwide. Children aged 6—23 months who receive a minimum dietary diversity. This indicator is the percentage of children aged 6—23 months who receive a minimum dietary diversity.

As per revised recommendation by TEAM in June , dietary diversity is present when the diet contained five or more of the following food groups: Children aged 6—23 months who receive a minimum acceptable diet. This indicator is the percentage of children aged 6—23 months who receive a minimum acceptable diet.

Proportion of children aged months who receive a minimum acceptable diet is included as a process indicator in the core set of indicators for the Global Nutrition Monitoring Framework. The composite indicator of a minimum acceptable diet is calculated from: Dietary diversity is present when the diet contained four or more of the following food groups: The minimum daily meal frequency is defined as: A minimum acceptable diet is essential to ensure appropriate growth and development for feeding infants and children aged 6—23 months.

Without adequate diversity and meal frequency, infants and young children are vulnerable to malnutrition, especially stunting and micronutrient deficiencies, and to increased morbidity and mortality. Source of all infant and young child feeding indicators. Infant and Young Child Feeding database. Infant and young child feeding list of publications. Global Nutrition Monitoring Framework. Children with diarrhoea receiving oral rehydration therapy and continued feeding.

This indicator is the prevalence of children with diarrhoea who received oral rehydration therapy and continued feeding. It is the proportion of children aged months who had diarrhoea and were treated with oral rehydration salts or an appropriate household solution and continued feeding. As oral rehydration therapy is a critical component of effective management of diarrhoea, monitoring coverage with this highly cost-effective intervention indicates progress towards the child survival-related Millennium Development Goals.

Health expenditure includes that for the provision of health services, family planning activities, nutrition activities and emergency aid designated for health, but excludes the provision of water and sanitation.

Health financing is a critical component of health systems. National health accounts provide a large set of indicators based on information on expenditure collected within an internationally recognized framework. National health accounts consist of a synthesis of the financing and spending flows recorded in the operation of a health system, from funding sources and agents to the distribution of funds between providers and functions of health systems and benefits geographically, demographically, socioeconomically and epidemiologically.

General government expenditure on health as a percentage of total government expenditure is the proportion of total government expenditure on health. General government expenditure includes consolidated direct and indirect outlays, such as subsidies and transfers, including capital, of all levels of government social security institutions, autonomous bodies and other extrabudgetary funds.

It consists of recurrent and capital spending from government central and local budgets, external borrowings and grants including donations from international agencies and nongovernmental organizations and social or compulsory health insurance funds. GDP is the value of all final goods and services produced within a nation in a given year. Public health expenditure consists of recurrent and capital spending from government central and local budgets, external borrowings and grants including donations from international agencies and nongovernmental organizations and social or compulsory health insurance funds.

Private health expenditure is the sum of outlays for health by private entities, such as commercial or mutual health insurance providers, non-profit institutions serving households, resident corporations and quasi-corporations not controlled by government involved in health services delivery or financing, and direct household out-of-pocket payments.

These indicators reflect total and public expenditure on health resources, access and services, including nutrition. Although increasing health expenditures are associated with better health outcomes, especially in low-income countries, there is no 'recommended' level of spending on health.

The larger the per capita income, the greater the expenditure on health. Some countries, however, spend appreciably more than would be expected from their income levels, and some appreciably less. When a government spends little of its GDP or attributes less of its total expenditure on health, this may indicate that health, including nutrition , are not regarded as priorities.

Wealth, health and health expenditure. General government expenditure on health as a percentage of total government expenditure is defined as the level of general government expenditure on health GGHE expressed as a percentage of total government expenditure.

The indicator contributes to understanding the weight of public spending on health within the total value of public sector operations. It includes not just the resources channelled through government budgets but also the expenditure on health by parastatals, extrabudgetary entities and notably the compulsory health insurance.

The indicator refers to resources collected and pooled by public agencies including all the revenue modalities. The indicator provides information on the level of resources channelled to health relative to a country's wealth. These indicators reflect government and total expenditure on health resources, access and services, including nutrition, in relation to government expenditure, the wealth of the country, and per capita.

When a government attributes less of its total expenditure on health, this may indicate that health, including nutrition , are not regarded as priorities. UNDAFs usually focus on three to five areas in which the country team can make the greatest difference, in addition to activities supported by other agencies in response to national demands but which fall outside the common UNDAF results matrix.

For each national priority selected for United Nations country team support, the UNDAF results matrix gives the outcome s , the outcomes and outputs of other agencies working alone or together, the role of partners, resource mobilization targets for each agency outcome and coordination mechanisms and programme modalities.

The nutrition component of the UNDAF reflects the priority attributed to nutrition by the United Nations agencies in a country and is an indication of how much the United Nations system is committed to helping governments improve their food and nutrition situation.

The indicator is "strong", "medium" or "weak", depending on the degree to which nutrition is being addressed in the expected outcomes and outputs in the UNDAF. UNDAF documents follow a predefined format, with a core narrative and a results matrix.

The matrix lists the high-level expected results 'the UNDAF outcomes' , the outcomes to be reached by agencies working alone or together and agency outputs. The results matrix the UNDAF document was used to assess commitment to nutrition , because it represents a synthesis of the strategy proposed in the document and is available in the same format in most country documents. The outcomes and outputs specifically related to nutrition were identified and counted.

The outputs were compared with the evidence-based interventions to reduce maternal and child under nutrition recommended in the Lancet Nutrition Series Bhutta et al. The method and scoring are described in detail by Engesveen et al.

What are the implications? A weak nutrition component in the UNDAF document does not necessarily imply that no United Nations agency in the country is working to improve nutrition ; however, unless such efforts are mentioned in strategy documents like the UNDAF, they may receive inadequate attention from development partners to ensure the necessary sustainability or scale-up to adequately address nutrition problems in the country.

The multisectoral nature of nutrition means that it must be addressed by a wide range of actors. Basing such action in frameworks for overall development contributes to ensuring the accountability of United Nations partners. Interventions for maternal and child under nutrition and survival.

The Lancet Engesveen K et al. SCN News , Nutrition component of poverty reduction strategy papers. The poverty reduction strategy approach was introduced in to empower governments to set their own priorities and to encourage donors to provide predictable, harmonized assistance aligned with country priorities. The PRSP should state the development priorities and specify the policies, programmes and resources needed to meet the goals.

It is prepared by governments in a participatory process involving civil society and development partners, including the World Bank and the International Monetary Fund, and should result in a comprehensive, country-based strategy for poverty reduction. The indicator is "strong", "medium" or "weak", depending on the degree to which nutrition is addressed in the PRSP, in terms of recognition of under nutrition as a development problem, use of information on nutrition to analyse poverty and support for appropriate nutrition policies, strategies and programmes.

The papers were systematically searched for key words to identify the parts that concerned nutrition , food security , health outcomes and interventions that would be relevant for the World Bank method.

In order to classify the commitments to nutrition in the PRSPs, a scoring system was developed, which is described in more detail by Engesveen et al. The emphasis given to nutrition in PRSPs reflects the extent to which the government considers it essential to improve nutrition for poverty reduction and national development.

In other words, it can be an indication of the government's priority for improving nutrition. A strong nutrition component in a PRSP means that the government considers nutrition a priority for poverty reduction and national development. A weak nutrition component in the document does not necessarily imply that no government department is working to improve nutrition ; however, unless such efforts are mentioned in strategy documents like PRSPs, they may not be sufficiently sustainable or be scaled-up to adequately address nutrition problems in the country.

Basing such action in frameworks for overall development contributes to ensuring the accountability of relevant government departments. Sources and further reading. Poverty reduction strategy papers. Assessing countries' commitment to accelerate nutrition action demonstrated in poverty reduction strategy paper, UNDAF and through nutrition governance.

SCN News , , Shekar M, Lee Y-K. Mainstreaming nutrition in poverty reduction strategy papers: What does it take? A review of the early experience. Health, Nutrition and Population Discussion Paper, Landscape analysis on countries' readiness to accelerate action in nutrition , This indicator is a description of the strengths and weaknesses of various aspects of nutrition governance in countries.

The following 10 elements or characteristics are used to assess and describe the strength of nutrition governance: These elements were identified by countries as key elements for successful development and implementation of national nutrition policies and strategies during a review of the progress of countries in implementing the World Declaration and Plan of Action for Nutrition adopted by the International Conference on Nutrition, the first intergovernmental conference on nutrition Nishida et al.

The components of the composite indicator have been identified by countries as important for determining the completeness of national nutrition plans and policies Nishida, Mutru, Imperial Laue , For instance, a national nutrition plan and policy was considered to provide the political basis for initiating action.

In many countries, official government endorsement or adoption of a national nutrition plan or policy facilitated its implementation. The role of an intersectoral coordinating committee in implementing national nutrition plans and policies was also considered crucial, although the nature i.

Another important element was considered to be regular surveys and other means of collecting data on nutrition. A periodically updated national nutrition information system and routinely collected data on food and nutrition were considered important for evaluating the effectiveness of national nutrition plans and policies and identifying subsequent actions.

Strategies for effective and sustainable national nutrition plans and policies. Modern aspects of nutrition , present knowledge and future perspective. Basel , Karger Forum for Nutrition 56 , This indicates whether a government has adopted legislation to monitor and enforce the International Code of Marketing of Breast-milk Substitutes, which helps create an environment that enables mothers to make the best possible feeding choice, based on impartial information and free of commercial influences, and to be fully supported in doing so.

This indicator is defined on the basis of whether a government has adopted legislation for effective national implementation and monitoring of the International Code of Marketing of Breast-milk Substitutes.

The Code is a set of recommendations to regulate the marketing of breast-milk substitutes, feeding bottles and teats. The Code aims to contribute "to the provision of safe and adequate nutrition for infants, by the protection and promotion of breastfeeding, and by ensuring the proper use of breast-milk substitutes, when these are necessary, on the basis of adequate information and through appropriate marketing and distribution" Article 1.

Improper marketing and promotion of food products that compete with breastfeeding often negatively affect the choice and ability of a mother to breastfeed her infant optimally. The Code was formulated in response to the realization that such marketing resulted in poor infant feeding practices, which negatively affect the growth, health and development of children and are a major cause of mortality in infants and young children.

Breastfeeding practices worldwide are not yet optimal, in both developing and developed countries, especially for exclusive breastfeeding under 6 months of age. In addition to the risks posed by the lack of the protective qualities of breast milk, breast-milk substitutes and feeding bottles are associated with a high risk for contamination that can lead to life-threatening infections in young infants.

Infant formula is not a sterile product, and it may carry germs that can cause fatal illnesses. Artificial feeding is expensive, requires clean water, the ability of the mother or caregiver to read and comply with mixing instructions and a minimum standard of overall household hygiene. These factors are not present in many households in the world. Frequently asked questions , These indicators provide information on national policies for legal entitlement to maternity protection, including leave from work during pregnancy and after birth, as well breastfeeding entitlements after return to work.

Since the International Labour Organization ILO was founded in , international labour standards have been established to provide maternity protection for women workers. Key elements of maternity protection include: The right to cash benefits during absence for maternity leave is intended to ensure that the woman can maintain herself and her child in proper conditions of health and with a suitable standard of living.

The source of benefits is important due to potential discrimination in the labour market if employers have to bear the full costs. The right to continue breastfeeding a child after returning to work is important since duration of leave entitlements generally is shorter than the WHO recommended duration of exclusive and continued breastfeeding.

A composite indicator on maternity protection is included as a policy environment and capacity indicator in the core set of indicators for the Global Nutrition Monitoring Framework.

It currently uses the ILO classification of compliance with Convention on three key provisions leave duration, remuneration and source of cash benefits , but an alternative method taking into account higher standards as stated in Recommendation as well as breastfeeding entitlements is under development.

The ILO periodically publishes information on the above key indicators, including the assessment of compliance with Convention No. However, an alternative method is under development which may use a scale to indicate the degree of compliance is under development.

This method will also take into account higher standards for leave duration and remuneration in Recommendation , as well as breastfeeding entitlements within both the Convention and Recommendation. Pregnancy and maternity are potentially vulnerable time for working women and their families.

Expectant and nursing mothers require special protection to prevent any potential adverse effects for them and their infants. They need adequate time to give birth, to recover from delivery process, and to nurse their children. At the same time, they also require income security and protection to ensure that they will not suffer from income loss or lose their job because of pregnancy or maternity leave.

Such protection not only ensures a woman's equal access and right to employment, it also ensures economic sustainability for the well-being of the family.

Returning to work after maternity leave has been identified as a significant cause for never starting breastfeeding, early cessation of breastfeeding and lack of exclusive breastfeeding. In most low- and middle-income countries, paid maternity leave is limited to formal sector employment or is not always provided in practice. The ILO estimates that more than million women lack economic security around childbirth with adverse effects on the health, nutrition and well-being of mothers and their children.

Maternity cash benefits for workers in the informal economy. Rollins et al Why invest, and what it will take to improve breastfeeding practices? Database of national labour, social security and related human rights legislation.

The legislative data are collected by ILO through periodical reviews of national labour and social security legislation and secondary sources, such as the International Social Security Association and International Network on Leave Policies and Research; as well as consultations with ILO experts in regional and national ILO offices around the world.

The composite indicator on maternity protection included in the Global Nutrition Monitoring Framework is currently defined as whether the country has maternity protection laws or regulations in place compliant with the provisions for leave duration, remuneration and source of cash benefits in Convention Documentation for the maternity protection database http: Degree training in nutrition exists.

What does the indicator tell us? This indicator reflects the capacity of a country to train professionals in nutrition in terms of having national higher education institutions offering training in nutrition.

This indicator is defined as the existence of higher education institutions offering training in nutrition in the country. Higher education training institutions include universities and other schools offering graduate and post-graduate degrees in nutrition or dietetics, including public health nutrition, community nutrition, food and nutrition policy, clinical nutrition, nutrition science and epidemiology.

Trained nutrition professionals work at facilities including health facilities as well as at population and community levels and may influence nutrition policies, and designing and implementation of nutrition intervention programmes at various levels. They also play an important role in training of other health and non-health cadres to plan and deliver nutrition interventions in various settings.

It is recognized that availability, within a country, of sufficient workforce with appropriate training in nutrition will lead to better outcomes for country-specific nutrition and health concerns.

A competency framework for global public health nutrition workforce development: World Public Health Nutrition Association. Registering as Registered Nutritionist. Building systemic capacity for nutrition: Nutrition is part of medical curricula. This indicator reflects the inclusion of maternal, infant and young child nutrition in pre-service training of health personnel.

This indicator is defined as the existence of pre-service training in maternal, infant and young child nutrition for health personnel.

The survey investigates training in three key areas of maternal, infant and young child nutrition, namely growth monitoring and promotion, breastfeeding and complementary feeding, and management of severe or moderate acute malnutrition.

The first two of these three training topics are relevant for all forms of malnutrition, whereas the third topic only pertains to undernutrition. One mustn't overlook the doctrines of Galen: In use from his life in the 1st century AD until the 17th century, it was heresy to disagree with him for years. Four elements earth, air, fire and water combine into "complexion", which combines into states the four temperaments: The states are made up of pairs of attributes hot and moist, cold and moist, hot and dry, and cold and dry , which are made of four humours: Galen thought that for a person to have gout , kidney stones , or arthritis was scandalous, which Gratzer likens to Samuel Butler's Erehwon where sickness is a crime.

In the s, Paracelsus was probably the first to criticize Galen publicly. Leonardo did not publish his works on this subject, but he was not afraid of thinking for himself and he definitely disagreed with Galen.

Jan Baptist van Helmont , who discovered several gases such as carbon dioxide , performed the first quantitative experiment. Robert Boyle advanced chemistry. Sanctorius measured body weight. Physician Herman Boerhaave modeled the digestive process. Physiologist Albrecht von Haller worked out the difference between nerves and muscles. Sometimes forgotten during his life, James Lind , a physician in the British navy, performed the first scientific nutrition experiment in Lind discovered that lime juice saved sailors that had been at sea for years from scurvy , a deadly and painful bleeding disorder.

Between and , an estimated two million sailors had died of scurvy. Around , Antoine Lavoisier discovered the details of metabolism, demonstrating that the oxidation of food is the source of body heat. Called the most fundamental chemical discovery of the 18th century, [30] Lavoisier discovered the principle of conservation of mass.

His ideas made the phlogiston theory of combustion obsolete. In , George Fordyce recognized calcium as necessary for the survival of fowl. In the early 19th century, the elements carbon , nitrogen , hydrogen , and oxygen were recognized as the primary components of food, and methods to measure their proportions were developed.

In , François Magendie discovered that dogs fed only carbohydrates sugar , fat olive oil , and water died evidently of starvation, but dogs also fed protein survived, identifying protein as an essential dietary component.

In the early s, Kanehiro Takaki observed that Japanese sailors whose diets consisted almost entirely of white rice developed beriberi or endemic neuritis, a disease causing heart problems and paralysis , but British sailors and Japanese naval officers did not. Adding various types of vegetables and meats to the diets of Japanese sailors prevented the disease, not because of the increased protein as Takaki supposed but because it introduced a few parts per million of thiamine to the diet, later understood as a cure [39].

In , Eugen Baumann observed iodine in thyroid glands. In , Christiaan Eijkman worked with natives of Java , who also suffered from beriberi. Eijkman observed that chickens fed the native diet of white rice developed the symptoms of beriberi but remained healthy when fed unprocessed brown rice with the outer bran intact. His assistant, Gerrit Grijns correctly identified and described the anti-beriberi substance in rice.

Eijkman cured the natives by feeding them brown rice, discovering that food can cure disease. Over two decades later, nutritionists learned that the outer rice bran contains vitamin B1, also known as thiamine. In the early 20th century, Carl von Voit and Max Rubner independently measured caloric energy expenditure in different species of animals, applying principles of physics in nutrition.

In , Edith G. Willcock and Frederick Hopkins showed that the amino acid tryptophan aids the well-being of mice but it did not assure their growth. Babcock and Edwin B. Hart started the cow feeding, single-grain experiment , which took nearly four years to complete. In , Casimir Funk coined the term vitamin , a vital factor in the diet, from the words "vital" and "amine," because these unknown substances preventing scurvy, beriberi, and pellagra , were thought then to be derived from ammonia.

The vitamins were studied in the first half of the 20th century. In , Elmer McCollum and Marguerite Davis discovered the first vitamin, fat-soluble vitamin A , then water-soluble vitamin B in ; now known to be a complex of several water-soluble vitamins and named vitamin C as the then-unknown substance preventing scurvy.

In , Sir Edward Mellanby incorrectly identified rickets as a vitamin A deficiency because he could cure it in dogs with cod liver oil. Bishop discover vitamin E as essential for rat pregnancy, originally calling it "food factor X" until In , Hart discovered that trace amounts of copper are necessary for iron absorption.

In , Albert Szent-Györgyi isolated ascorbic acid , and in proved that it is vitamin C by preventing scurvy. In , he synthesized it, and in , he won a Nobel Prize for his efforts. Szent-Györgyi concurrently elucidated much of the citric acid cycle. In the s, William Cumming Rose identified essential amino acids , necessary protein components that the body cannot synthesize. In , Underwood and Marston independently discovered the necessity of cobalt. In , Eugene Floyd DuBois showed that work and school performance are related to caloric intake.

In , Erhard Fernholz discovered the chemical structure of vitamin E and then he tragically disappeared. In , rationing in the United Kingdom during and after World War II took place according to nutritional principles drawn up by Elsie Widdowson and others. In , The U. Department of Agriculture introduced the Food Guide Pyramid.

The list of nutrients that people are known to require is, in the words of Marion Nestle , "almost certainly incomplete". Some nutrients can be stored - the fat-soluble vitamins - while others are required more or less continuously.

Poor health can be caused by a lack of required nutrients, or for some vitamins and minerals, too much of a required nutrient. The macronutrients are carbohydrates , fiber , fats , protein , and water.

Some of the structural material can be used to generate energy internally, and in either case it is measured in Joules or kilocalories often called "Calories" and written with a capital C to distinguish them from little 'c' calories. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons. Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms.

Carbohydrates range from simple monosaccharides glucose, fructose and galactose to complex polysaccharides starch. Fats are triglycerides , made of assorted fatty acid monomers bound to a glycerol backbone.

Some fatty acids, but not all, are essential in the diet: Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen. The fundamental components of protein are nitrogen-containing amino acids , some of which are essential in the sense that humans cannot make them internally.

Some of the amino acids are convertible with the expenditure of energy to glucose and can be used for energy production, just as ordinary glucose, in a process known as gluconeogenesis. By breaking down existing protein, the carbon skeleton of the various amino acids can be metabolized to intermediates in cellular respiration; the remaining ammonia is discarded primarily as urea in urine.

Carbohydrates may be classified as monosaccharides , disaccharides , or polysaccharides depending on the number of monomer sugar units they contain. They constitute a large part of foods such as rice , noodles , bread , and other grain -based products, also potatoes , yams, beans, fruits, fruit juices and vegetables.

Monosaccharides, disaccharides, and polysaccharides contain one, two, and three or more sugar units, respectively. Polysaccharides are often referred to as complex carbohydrates because they are typically long, multiple branched chains of sugar units. Traditionally, simple carbohydrates are believed to be absorbed quickly, and therefore to raise blood-glucose levels more rapidly than complex carbohydrates.

This, however, is not accurate. Dietary fiber is a carbohydrate that is incompletely absorbed in humans and in some animals. Like all carbohydrates, when it is metabolized it can produce four Calories kilocalories of energy per gram. However, in most circumstances it accounts for less than that because of its limited absorption and digestibility.

Dietary fiber consists mainly of cellulose, a large carbohydrate polymer which is indigestible as humans do not have the required enzymes to disassemble it. There are two subcategories: Whole grains, fruits especially plums , prunes , and figs , and vegetables are good sources of dietary fiber. There are many health benefits of a high-fiber diet. Dietary fiber helps reduce the chance of gastrointestinal problems such as constipation and diarrhea by increasing the weight and size of stool and softening it.

Insoluble fiber, found in whole wheat flour , nuts and vegetables, especially stimulates peristalsis ;— the rhythmic muscular contractions of the intestines, which move digest along the digestive tract.

Soluble fiber, found in oats, peas, beans, and many fruits, dissolves in water in the intestinal tract to produce a gel that slows the movement of food through the intestines. This may help lower blood glucose levels because it can slow the absorption of sugar. Additionally, fiber, perhaps especially that from whole grains, is thought to possibly help lessen insulin spikes, and therefore reduce the risk of type 2 diabetes.

The link between increased fiber consumption and a decreased risk of colorectal cancer is still uncertain. A molecule of dietary fat typically consists of several fatty acids containing long chains of carbon and hydrogen atoms , bonded to a glycerol. They are typically found as triglycerides three fatty acids attached to one glycerol backbone. Fats may be classified as saturated or unsaturated depending on the detailed structure of the fatty acids involved.

Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded , so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length.

Unsaturated fats may be further classified as monounsaturated one double-bond or polyunsaturated many double-bonds. Furthermore, depending on the location of the double-bond in the fatty acid chain, unsaturated fatty acids are classified as omega-3 or omega-6 fatty acids.

Trans fats are a type of unsaturated fat with trans -isomer bonds; these are rare in nature and in foods from natural sources; they are typically created in an industrial process called partial hydrogenation. There are nine kilocalories in each gram of fat. Fatty acids such as conjugated linoleic acid , catalpic acid, eleostearic acid and punicic acid , in addition to providing energy, represent potent immune modulatory molecules.

Saturated fats typically from animal sources have been a staple in many world cultures for millennia. Saturated and some trans fats are typically solid at room temperature such as butter or lard , while unsaturated fats are typically liquids such as olive oil or flaxseed oil. Trans fats are very rare in nature, and have been shown to be highly detrimental to human health, but have properties useful in the food processing industry, such as rancidity resistance.

Most fatty acids are non-essential, meaning the body can produce them as needed, generally from other fatty acids and always by expending energy to do so. However, in humans, at least two fatty acids are essential and must be included in the diet. An appropriate balance of essential fatty acids— omega-3 and omega-6 fatty acids —seems also important for health, although definitive experimental demonstration has been elusive.

Both of these "omega" long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins , which have roles throughout the human body. They are hormones , in some respects. The omega-3 eicosapentaenoic acid EPA , which can be made in the human body from the omega-3 essential fatty acid alpha-linolenic acid ALA , or taken in through marine food sources, serves as a building block for series 3 prostaglandins e.

The omega-6 dihomo-gamma-linolenic acid DGLA serves as a building block for series 1 prostaglandins e. An appropriately balanced intake of omega-3 and omega-6 partly determines the relative production of different prostaglandins, which is one reason why a balance between omega-3 and omega-6 is believed important for cardiovascular health.

In industrialized societies, people typically consume large amounts of processed vegetable oils, which have reduced amounts of the essential fatty acids along with too much of omega-6 fatty acids relative to omega-3 fatty acids. Moreover, the conversion desaturation of DGLA to AA is controlled by the enzyme deltadesaturase , which in turn is controlled by hormones such as insulin up-regulation and glucagon down-regulation.

The amount and type of carbohydrates consumed, along with some types of amino acid, can influence processes involving insulin, glucagon, and other hormones; therefore, the ratio of omega-3 versus omega-6 has wide effects on general health, and specific effects on immune function and inflammation , and mitosis i. Proteins are structural materials in much of the animal body e.

They also form the enzymes that control chemical reactions throughout the body. Each protein molecule is composed of amino acids , which are characterized by inclusion of nitrogen and sometimes sulphur these components are responsible for the distinctive smell of burning protein, such as the keratin in hair. The body requires amino acids to produce new proteins protein retention and to replace damaged proteins maintenance. As there is no protein or amino acid storage provision, amino acids must be present in the diet.

Excess amino acids are discarded, typically in the urine. For all animals, some amino acids are essential an animal cannot produce them internally and some are non-essential the animal can produce them from other nitrogen-containing compounds.

About twenty amino acids are found in the human body, and about ten of these are essential and, therefore, must be included in the diet.

A diet that contains adequate amounts of amino acids especially those that are essential is particularly important in some situations: A complete protein source contains all the essential amino acids; an incomplete protein source lacks one or more of the essential amino acids.

It is possible with protein combinations of two incomplete protein sources e. However, complementary sources of protein do not need to be eaten at the same meal to be used together by the body. Water is excreted from the body in multiple forms; including urine and feces , sweating , and by water vapour in the exhaled breath.

Therefore, it is necessary to adequately rehydrate to replace lost fluids. Early recommendations for the quantity of water required for maintenance of good health suggested that 6—8 glasses of water daily is the minimum to maintain proper hydration. Most of this quantity is contained in prepared foods. For healthful hydration, the current EFSA guidelines recommend total water intakes of 2.

These reference values include water from drinking water, other beverages, and from food. The EFSA panel also determined intakes for different populations. Recommended intake volumes in the elderly are the same as for adults as despite lower energy consumption, the water requirement of this group is increased due to a reduction in renal concentrating capacity. Dehydration and over-hydration - too little and too much water, respectively - can have harmful consequences.

Drinking too much water is one of the possible causes of hyponatremia , i. Pure ethanol provides 7 calories per gram. For distilled spirits , a standard serving in the United States is 1. A 5 ounce serving of wine contains to calories. A 12 ounce serving of beer contains 95 to calories.

Alcoholic beverages are considered empty calorie foods because other than calories, these contribute no essential nutrients. The micronutrients are minerals , vitamins , and others.

Dietary minerals are inorganic chemical elements required by living organisms, [70] other than the four elements carbon , hydrogen , nitrogen , and oxygen that are present in nearly all organic molecules. The term "mineral" is archaic, since the intent is to describe simply the less common elements in the diet. Some are heavier than the four just mentioned, including several metals , which often occur as ions in the body. Some dietitians recommend that these be supplied from foods in which they occur naturally, or at least as complex compounds, or sometimes even from natural inorganic sources such as calcium carbonate from ground oyster shells.

Some minerals are absorbed much more readily in the ionic forms found in such sources. On the other hand, minerals are often artificially added to the diet as supplements; the most famous is likely iodine in iodized salt which prevents goiter. Many elements are essential in relative quantity; they are usually called "bulk minerals". Some are structural, but many play a role as electrolytes.

Many elements are required in trace amounts, usually because they play a catalytic role in enzymes. Vitamins are essential nutrients, [70] necessary in the diet for good health.

Vitamin D is an exception, as it can be synthesized in the skin in the presence of UVB radiation , and many animal species can synthesize vitamin C. Vitamin deficiencies may result in disease conditions, including goitre , scurvy , osteoporosis , impaired immune system, disorders of cell metabolism, certain forms of cancer, symptoms of premature aging, and poor psychological health , among many others. Phytochemicals such as polyphenols are compounds produced naturally in plants phyto means "plant" in Greek.

In general, the term is used to refer to compounds which do not appear to be nutritionally essential and yet may have positive impacts on health. To date, there is no conclusive evidence in humans that polyphenols or other non-nutrient compounds from plants have health benefit effects.

While initial studies sought to reveal if nutrient antioxidant supplements might promote health, one meta-analysis concluded that supplementation with vitamins A and E and beta-carotene did not convey any benefits and may in fact increase risk of death. Vitamin C and selenium supplements did not impact mortality rate. Health effects of non-nutrient phytochemicals such as polyphenols were not assessed in this review. Animal intestines contain a large population of gut flora.

In humans, the four dominant phyla are Firmicutes , Bacteroidetes , Actinobacteria , and Proteobacteria. Bacteria in the large intestine perform many important functions for humans, including breaking down and aiding in the absorption of fermentable fiber, stimulating cell growth, repressing the growth of harmful bacteria, training the immune system to respond only to pathogens, producing vitamin B 12 , and defending against some infectious diseases.

There is not yet a scientific consensus as to health benefits accruing from probiotics or prebiotics. Carnivore and herbivore diets are contrasting, with basic nitrogen and carbon proportions vary for their particular foods.

Many herbivores rely on bacterial fermentation to create digestible nutrients from indigestible plant cellulose, while obligate carnivores must eat animal meats to obtain certain vitamins or nutrients their bodies cannot otherwise synthesize. Plant nutrition is the study of the chemical elements that are necessary for plant growth.

Some elements are directly involved in plant metabolism. However, this principle does not account for the so-called beneficial elements, whose presence, while not required, has clear positive effects on plant growth.

A nutrient that is able to limit plant growth according to Liebig's law of the minimum is considered an essential plant nutrient if the plant cannot complete its full life cycle without it. There are 16 essential plant soil nutrients, besides the three major elemental nutrients carbon and oxygen that are obtained by photosynthetic plants from carbon dioxide in air, and hydrogen , which is obtained from water.

Plants uptake essential elements from the soil through their roots and from the air consisting of mainly nitrogen and oxygen through their leaves. Green plants obtain their carbohydrate supply from the carbon dioxide in the air by the process of photosynthesis. Carbon and oxygen are absorbed from the air, while other nutrients are absorbed from the soil. These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root.

In the leaves, stomata open to take in carbon dioxide and expel oxygen. The carbon dioxide molecules are used as the carbon source in photosynthesis. Although nitrogen is plentiful in the Earth's atmosphere, very few plants can use this directly.

Most plants, therefore, require nitrogen compounds to be present in the soil in which they grow. This is made possible by the fact that largely inert atmospheric nitrogen is changed in a nitrogen fixation process to biologically usable forms in the soil by bacteria.

Plant nutrition is a difficult subject to understand completely, partially because of the variation between different plants and even between different species or individuals of a given clone. Elements present at low levels may cause deficiency symptoms, and toxicity is possible at levels that are too high.

Furthermore, deficiency of one element may present as symptoms of toxicity from another element, and vice versa. Canada's Food Guide is an example of a government-run nutrition program. Produced by Health Canada , the guide advises food quantities, provides education on balanced nutrition, and promotes physical activity in accordance with government-mandated nutrient needs.

Like other nutrition programs around the world, Canada's Food Guide divides nutrition into four main food groups: Dietary and physical activity guidelines from the USDA are presented in the concept of MyPlate , which superseded the food pyramid , which replaced the Four Food Groups. Department of Health and Human Services provides a sample week-long menu that fulfills the nutritional recommendations of the government.

Governmental organisations have been working on nutrition literacy interventions in non-primary health care settings to address the nutrition information problem in the U. The FNP has developed a series of tools to help families participating in the Food Stamp Program stretch their food dollar and form healthful eating habits including nutrition education.

It is designed to assist limited-resource audiences in acquiring the knowledge, skills, attitudes, and changed behavior necessary for nutritionally sound diets, and to contribute to their personal development and the improvement of the total family diet and nutritional well-being. Launched in , this program promotes lifelong healthful eating patterns and physically active lifestyles for children and their families. It is an interactive educational program designed to help prevent childhood obesity through classroom activities that teach children healthful eating habits and physical exercise.

Nutrition is taught in schools in many countries. In England and Wales , the Personal and Social Education and Food Technology curricula include nutrition, stressing the importance of a balanced diet and teaching how to read nutrition labels on packaging. In many schools, a Nutrition class will fall within the Family and Consumer Science or Health departments. In some American schools, students are required to take a certain number of FCS or Health related classes. Nutrition is offered at many schools, and, if it is not a class of its own, nutrition is included in other FCS or Health classes such as: In many Nutrition classes, students learn about the food groups, the food pyramid, Daily Recommended Allowances, calories, vitamins, minerals, malnutrition, physical activity, healthful food choices, portion sizes, and how to live a healthy life.

In the US, Registered dietitian nutritionists RDs or RDNs [89] are health professionals qualified to provide safe, evidence-based dietary advice which includes a review of what is eaten, a thorough review of nutritional health, and a personalized nutritional treatment plan. They also provide preventive and therapeutic programs at work places, schools and similar institutions. Certified Clinical Nutritionists or CCNs, are trained health professionals who also offer dietary advice on the role of nutrition in chronic disease, including possible prevention or remediation by addressing nutritional deficiencies before resorting to drugs.

These Board Certified Nutritionists typically specialize in obesity and chronic disease. In order to become board certified, potential CNS candidate must pass an examination, much like Registered Dieticians. This exam covers specific domains within the health sphere including; Clinical Intervention and Human Health. The study found that health literacy increases with education and people living below the level of poverty have lower health literacy than those above it.

Another study examining the health and nutrition literacy status of residents of the lower Mississippi Delta found that 52 percent of participants had a high likelihood of limited literacy skills.
