Nutrition Landscape Information System (NLiS)
One standard means of determining if a person has had a particular disease is to test for the presence of antibodies that are particular to this disease. The human development index is a summary measure of human development. 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 Br Dent J ; For the medical journal, see Nutrition journal.
If data already collected are used or if a new survey is carried out for use on a higher level, the size and representativeness of the sample must be checked, and it must be ensured that the data can be linked to a more general set on the basis of common indicators collected under the same conditions method, period, etc. Verification of the quality of the data is crucial. Before undertaking a specific data collection, a list of indicators and of corresponding raw data should be developed which can be used by services at all levels; it is not unusual to find that surveys could have been avoided by a better knowledge of the data available from different sources.
To track down these useful sources and judge the quality of the data available and their level of aggregation, a good understanding is needed of the goals and procedures of the underlying information system. The country had set up a monthly national information system on production estimates for 35 crops, covering information on crop intentions, areas actually planted, crop yields and quantities harvested in each state.
The information was obtained during monthly meetings of experts at various levels - local, regional and national. The information was then put together at the state level, and then at the national level, reviewed by a national committee of experts, and sent on to the central statistics office. The different levels thus had some rich information at their disposal, coming from a range of local-level sources. Although it was certainly fairly reliable, being confirmed by a large number of stakeholders and experts, its precision could not be defined, in view of its diversity.
The usefulness of such data varies depending on information needs and thus on the quality of the data required. Data concentrated at the central level are probably useful primarily for analysing trends. On the other hand, apart from the figures, more general information on production systems exists at local level, and this can be useful for identifying relevant indicators of causes, or for simplifying monitoring of the situation. We have seen that there is a great number of indicators which differ widely in quality; the availability of corresponding data is variable, and any active collection will be subject to constraints.
Therefore the choice of indicators must be restricted to the real needs of decision makers or programme planners. This implies that a method is needed for guiding the choice.
The main elements that will guide choice are: Any intervention is based on an analysis of the situation, an understanding of the factors that determine this situation, and the formulation of hypotheses regarding programmes able to improve the situation. A general framework was presented earlier see Figure , representing a holistic model of causes of malnutrition and mortality, which was endorsed by most international organizations and nutrition planners. However, the convenient classification that it implies, for instance into levels of immediate, underlying or basic causes needs to be operationalized through further elaboration in context.
The benefit of constructing such a framework, over and above the complete review of the chain of events which determine the nutritional situation, is to allow the expression, in measurable terms, of general concepts which, because of their complexity, are not always well defined.
For example, it is not enough to refer to "food security"; one should state which of the existing definitions is to be used, on which dimensions of food security the focus is placed and the corresponding indicators. The use of conceptual frameworks when implementing programmes or planning food and nutrition is not new. Many examples have been developed, focusing on different aspects. The concept of food security is generally perceived as that of sufficient availability of food for all.
However, several dozen different definitions have been proposed over these last 15 years! This concept may, for example, comprise different aspects depending on the level being related to: In the first case, analysis will focus on agricultural production, and in the second the emphasis will be on improving the resources of those who lack access to a correct diet.
This preliminary brainstorming exercise will allow a better definition of the perceived chain of causes production shortfall, excessive market prices, defective marketing infrastructures, low minimum wage, low level of education, etc. It will then be easier to consider potential indicators of the situation and its causes, or potential indicators of programme impact. Obviously it is not so much the final diagram which is of importance as the process through which it was developed. Insofar as the relations between all the links of the chain of events or flow data, depending on the type of representation have been discussed step by step and argued with supporting facts, the framework will be adapted to the local situation and will become operational.
Methodologies have been developed for making this process effective in the context of planning, for example with the method of "planning by objectives" see ZOPP , which comprises several phases: During this planning process, all programme activities, corresponding partners, necessary inputs and resulting outputs as well as indicators for both monitoring implementation and evaluating impact of the programme will be successively identified.
The method acts as a guide for team work, encouraging intersectoral analysis and offering a simplified picture of the situation, so that the results of discussions are clear to all in the team. Let us again take the example of a problem of food security. It can be broken down into three determining sectors: A series of structural elements can be defined for each sector: These elements affect both production levels and operation of markets.
A certain number of macro-economic or specific policies will affect one or all the elements in this block. Each block can be considered in a similar way, and this will provide the groundwork for a theoretical model of how the system works see C.
The final steps in order to operationalize the model are i that of defining indicators that will, in the specific context of the country, reflect the key elements of the system, and ii , once policies and programmes have been chosen, that of identifying which of these indicators are useful for monitoring trends and evaluating programme impact.
This will be the basis for an information system reflecting the overall framework of the programme and how it should work. Another method has been proposed by researchers from the Institute of Tropical Medicine in Antwerp based on their field experience in collaboration with different partners Lefèvre et al.
Basically, it stresses the participatory aspect, with the aim of obtaining a true consensus on the local situation, the rationality of interventions in view of the situation, and the choice of indicators. It includes first a phase in which a causal framework is developed with the aim of providing an understanding of the mechanisms leading to undernutrition in the context under consideration. The framework is constructed in the form of a schematic, hierarchized diagram of causal hypotheses formulated after discussions among all stakeholders.
The way it is built tends to favour a clear, "vertical" visualization of series of causal relationships, eliminating the lateral links or loops that are often the source of confusion in other representations. In a second phase, a framework is developed linking the human or material resources available at the onset inputs , the procedures envisaged activities , the corresponding results of implementation outputs , and the anticipated intermediate outcomes or final impact of each activity or of the programme.
This tool is very useful for defining all the necessary indicators. This represents the formalisation of a real conceptual scheme. While many representations of conceptual models comprise comparable elements, it is essential that a model should never be considered as directly transposable, since it must absolutely apply to the local context.
A direct transposition would therefore be totally counter-productive. While it is obvious that the conceptual analysis must ideally be carried out before the programmes are launched, it can be done or updated at any time, leading to greater coherence and a consensus on current and anticipated actions; this applies even more in a long-term perspective of sustainability.
In operational terms, establishment of a conceptual framework allows to define in a coherent way the various types of indicators to be used at each level. After defining the activities to be undertaken, status indicators referring to the target group will be identified, as well as indicators of causes that will or will not be modified by these activities, and indicators that will reflect the level or quality of the activities performed.
Lastly, indicators will be chosen to reflect the changes obtained, whether or not these are a result of the programme. Identification of precise objectives makes it possible to monitor changes in impact indicators not only vis-à-vis the original situation but also in terms of fulfilment of the objectives adopted. During this initial phase, existing indicators are assessed, as well as those that will be taken from records or collected through specific surveys.
It should be specified who needs this information, as well as who collects the data. In fact, it is important that this choice should be demand-driven, in order to be sure that the information selected is then actually used. One might be dealing with several groups of users who do not exactly have the same needs: In this way, foundations can be laid for an information system essential for monitoring and evaluation. A proximate, often indirect, indicator will have to be sought and limitations to its validity in the context considered will have to be verified carefully which will depend on the precise objective.
For example, can a measurement of food stocks at a given moment be validly replaced in the context under consideration with a measurement of food consumption in order to assess the food insecurity situation of a target group? Is a measurement of food diversity a good proximate indicator for micronutrient intake?
Does it at least consistently classify consumers into strong and weak consumers? Does it allow defining an acceptable level of consumption vis-à-vis recommendations? Will it allow children to be classified correctly vis-à-vis a goal of improved growth? Validity studies are sometimes available locally, otherwise specific studies can be carried out; hence the usefulness of collaborating with research groups - for example from universities - who will be able to carry out this type of validation study under good conditions.
The relationship between two variables, making them interchangeable for defining an indicator, may vary over time as a result of implementation of a programme, and this must be taken into account.
For example, if there is a clear link between family size and food insecurity in a given context, the criterion of family size can simply be taken as a basis for identifying families at risk. However, if a specific programme has been successfully carried out among these families, this indicator could lose its validity.
The ideal would be to use the same indicators in all places and at all times in order to have the benefit of common experience regarding collection and analysis, so that direct comparisons can be made.
In practice, however, concepts on indicators evolve steadily with the progress of knowledge, leading to the dilemma of being unable to carry out comparisons either with older series of indicators or with what is being done elsewhere.
Comparability within time is obviously a priority in the case of monitoring. Preference will thus be given to indicators that, although not necessarily identical, are comparable, in other words give a similar type of information.
The issue of the comparability of data from different sources has been the subject of studies especially in the field of health indicators. Whenever traditional indicators seem inadequate or insufficient in capturing the phenomenon or situation under consideration, the value of "innovative" and potentially promising indicators with excellent basic characteristics should not be neglected - although it is important to make sure that they have been validated for circumstances similar to those under study.
Since such innovative indicators usually have to be collected "actively", especially at the community level, the decision often depends on their technical feasibility as a guarantee of the sustainability of collection. In a context of dietary transition, an indicator expressing the structure of food consumption for example the percent of energy from fat is more subject to major changes than the average consumption level expressed in calories, while also providing important information on the future health of the population considered.
In contrast, data on food habits tend not to change rapidly, unless an education programme is specifically developed for this purpose; the repeated collection of the corresponding indicators is thus of little use for purposes of short- or medium-term monitoring of the situation.
Slowness in collection and in getting the data back to user level are key factors to be considered, for many information systems are paralyzed by this problem, while timely information is often needed for decision-making or for adjusting the programme or the intervention e. From this point of view, the nature of potential sources of data for these indicators or the direct availability of these indicators at the level where they are needed can be decisive for their selection.
In practice, data collected to produce indicators need to be compared to a reference or to a "cut-off value". These can based on an international consensus within the scientific community or the political world, thus avoiding disagreement on interpretation and allowing comparisons between countries and regional extrapolations. Even so, the information is still sometimes insufficient; moreover, there are no international references for several categories of indicators.
In such cases, the value of the same variable at a previous date will be taken as a point of reference. Interpretation of changes in an indicator can be carried out only on the basis of our knowledge of the original situation; knowing a baseline therefore forms part of the information value of a number of indicators. For instance, was it better or worse before? The only information it supplies as such is the difference from a reference situation in a country without any major problem of undernutrition defined as a prevalence of 2.
The impact of a programme cannot be measured without knowledge of the situation at baseline. The existence of chronological series for an indicator will be considered when choosing among several indicators, because such series allow a rapid interpretation of impact in terms of trends.
When previous data are old, an effort is made to assess their present level by projection, as is usually done for major demographic or economic indicators.
In a certain number of cases, a preliminary survey is needed in order to establish the present level of various indicators. Many countries undertook national surveys of their nutritional situation prior to establishing their policies and programmes, so that they could decide on the type or scope of the programme, and could subsequently evaluate the impact.
Such surveys are not cheap, but their cost must be examined in regard to that of the programme to be developed, and of the potential cost linked to the lack of evaluation of a programme that fails to yield the expected results. When passive collection of data from existing sources does not provide the necessary indicators in an appropriate form, active collection should be considered through surveys among the population with an appropriate level of disaggregation.
This may also be needed when the administrative coverage of the population, particularly of groups at risk, is insufficient. Firstly, it is important to consider that the preferred level of expression of the indicators varies by discipline individuals for the expression of epidemiological risks, households for the level of food security, administrative units for an economist, etc.
The statistical units of measurement vary accordingly. These three expressions of the same situation cannot be treated in the same way statistically. Data that have been collected at different levels, must be analyzed accordingly. Depending on the type of indicator required, quantitative or qualitative survey techniques will be used, each based on specific methodologies.
A good understanding of the limitations of the data thus collected in terms of their interpretation, representativeness, accuracy and precision is crucial. Well-known guides written by specialists in each sphere are generally available.
For the collection of data on the nutritional status of a population, for example, the WHO and FAO have published guides describing the procedures to be followed for sampling, collecting and interpreting anthropometric measurements in the context of cross-sectional surveys WHO, ; FAO, There is also a guide for the main types of surveys on food consumption Cameron and van Staveren, and publications on household food security indicators and how to measure them Maxwell and Frankenberger, ; Delaine et al.
Appropriate methods have also been developed in the fields of demographics, health WHO, and economics, in order to establish rough indicators when most of the usual sources are lacking. These qualitative methods, developed and commonly used in the social sciences, especially anthropology, are now widely used in economics and agronomy Chambers, in combination with more traditional quantitative surveys, but those working in the food and nutrition sector are not always familiar with them.
A description of these methodologies, adapted to different uses, can be found in various publications Maxwell and Frankenberger, ; Chambers, ; Den Hartog and van Staveren, ; Kidima, Scrimshaw and Hurtado, Examples of application and comments on limits of interpretation also appear in the work by IFPRI already cited Von Braun and Puetz, and in Scrimshaw and Gleason Finally, a recent study presents an analysis of a substantial number of experiences in various fields Cornwall and Pratt, These surveys are based on observations or interviews, either open or structured and of varying lengths, concerning beliefs, perceptions, knowledge, behaviours or practices of individuals or social groups, with varying degrees of precision, triangulation or participation, and with results expressed in various forms diagrams, maps, calendars, case studies.
The main difficulty is to synthesize the information in order to reach a conclusion, so that the information collected can be used, without converting it inappropriately into reductive numerical data. Not every survey can, however, deal satisfactorily with everything. It is therefore important in this case to check that periodicity, level of collection, representativeness and confidence intervals are relevant for each indicator, otherwise it is better to undertake a separate survey suited to the indicator considered.
Surveys on sub-samples often save time and resources. It must also be ensured that the results can later be aggregated at an adequate level and in a coherent manner. Two classical approaches are inevitably opposed when survey procedures are defined: Should a food consumption survey be based on the "frequency method" allowing a large sample to be surveyed, or should the "weighing technique" be used, providing more precise estimates but on a smaller sample because the method is cumbersome?
These choices, which reflect initial objectives, must be made at the conception stage of the programme and not later, on the basis of resources available and skills of local field-workers. In developed countries and in many urban areas in developing countries, skilled care at delivery is usually provided in health facilities. Births do, however, take place in various other appropriate places, from home to tertiary referral centres, depending on availability and need.
WHO does not recommend a particular setting for giving birth. Home delivery may be appropriate for normal births, provided that the person attending the delivery is suitably trained and equipped and that referral to a higher level of care is an option, however this may lead to an overestimation of births attended by skilled personal as infants delivered outside of a health facility may not have their birth method recorded.
All women should have access to skilled care during pregnancy and at delivery to ensure the detection and management of complications. One woman dies needlessly of pregnancy-related causes every minute, representing more than half a million mothers lost each year, a figure that has improved little over the past few decades.
Another 8 million or more suffer life-long health consequences from the complications of pregnancy. The lack of progress in reducing maternal mortality in many countries often reflects the low value placed on the lives of women and their limited role in setting public priorities. The lives of many women in developing countries could be saved by reproductive health interventions that people in rich countries take for granted, such as the presence of skilled health personnel at delivery.
Improved sanitation facilit ies and drinking-water sources. What do these indicators tell us? These indicators are the percentage of population with access to an improved drinking-water source and improved sanitation facilities. 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.

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. As the lead organization in global public health, the WHO occupies a delicate role in global politics.
It must maintain good relationships with each of the many countries in which it is active. As a result, it may only report results within a particular country with the agreement of the country's government. Because some governments regard the release of any information on disease outbreaks as a state secret, this can place the WHO in a difficult position. The WHO coordinated International Outbreak Alert and Response is designed to ensure "outbreaks of potential international importance are rapidly verified and information is quickly shared within the Network" but not necessarily by the public; integrate and coordinate "activities to support national efforts" rather than challenge national authority within that nation in order to "respect the independence and objectivity of all partners".
The commitment that "All Network responses will proceed with full respect for ethical standards, human rights, national and local laws, cultural sensitivities and tradition" ensures each nation that its security, financial, and other interests will be given full weight. Testing for a disease can be expensive, and distinguishing between two diseases can be prohibitively difficult in many countries.
One standard means of determining if a person has had a particular disease is to test for the presence of antibodies that are particular to this disease.
In the case of H5N1, for example, there is a low pathogenic H5N1 strain in wild birds in North America that a human could conceivably have antibodies against. Similar difficulties are common, and make it difficult to determine how widely a disease may have spread.
There is currently little available data on the spread of H5N1 in wild birds in Africa and Asia. Without such data, predicting how the disease might spread in the future is difficult. Information that scientists and decision makers need to make useful medical products and informed decisions for health care, but currently lack include:. Surveillance of H5N1 in humans, poultry, wild birds, cats and other animals remains very weak in many parts of Asia and Africa.
Much remains unknown about the exact extent of its spread. H5N1 in China is less than fully reported.
