Global Antimicrobial Resistance Surveillance System (GLASS)
Active surveillance systems are most appropriate for epidemics or where a disease has been targeted for elimination. Techniques of public health surveillance have been used in particular to study infectious diseases.
Many large institutions, such as the WHO and the CDC , have created databases and modern computer systems public health informatics that can track and monitor emerging outbreaks of illnesses such as influenza , SARS , HIV , and even bioterrorism , such as the anthrax attacks in the United States. Many regions and countries have their own cancer registry , one function of which is to monitor the incidence of cancers to determine the prevalence and possible causes of these illnesses.
Other illnesses such as one-time events like stroke and chronic conditions such as diabetes , as well as social problems such as domestic violence, are increasingly being integrated into epidemiologic databases called disease registries that are being used in cost-benefit analysis in determining governmental funding for research and prevention. Systems that can automate the process of identifying adverse drug events, are currently being used, and are being compared to traditional written reports of such events.
Issues in regard to healthcare improvement are evolving around the surveillance of medication errors within institutions. Syndromic surveillance is the analysis of medical data to detect or anticipate disease outbreaks. According to a CDC definition, "the term 'syndromic surveillance' applies to surveillance using health-related data that precede diagnosis and signal a sufficient probability of a case or an outbreak to warrant further public health response.
Though historically syndromic surveillance has been utilized to target investigation of potential cases, its utility for detecting outbreaks associated with bioterrorism is increasingly being explored by public health officials. The first indications of disease outbreak or bioterrorist attack may not be the definitive diagnosis of a physician or a lab. Syndromic surveillance systems monitor data from school absenteeism logs, emergency call systems, hospitals' over-the-counter drug sale records, Internet searches, and other data sources to detect unusual patterns.
When a spike in activity is seen in any of the monitored systems disease epidemiologists and public health professionals are alerted that there may be an issue. An early awareness and response to a bioterrorist attack could save many lives and potentially stop or slow the spread of the outbreak.
The most effective syndromic surveillance systems automatically monitor these systems in real-time, do not require individuals to enter separate information secondary data entry , include advanced analytical tools, aggregate data from multiple systems, across geo-political boundaries and include an automated alerting process.
A syndromic surveillance system based on search queries was first proposed by Gunther Eysenbach , who began work on such a system in More flu -related searches are taken to indicate higher flu activity. The results closely match CDC data, and lead it by 1—2 weeks.
The results appeared in Nature. Influenzanet is a syndromic surveillance system based on voluntary reports of symptoms via the internet. Residents of the participant countries are invited to provide regular reports on the presence or absence of flu related symptoms.
The system has been in place and running since in the Netherlands and Belgium. 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.
National health accounts - World Health Statistics, http: Human development report http: Core health indicators http: Human development report indicator glossary for indicator 3. 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.

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: This surveillance system captures any disease, condition, or event that could represent an international risk. In the United States, disease reporting is mandated by state law, and the list of reportable diseases which is updated regularly by the Council of State and Territorial Epidemiologists and the CDC vary by state.
Routine surveys are surveillance tools especially useful for monitoring chronic diseases and health-related behaviors. Two of the national surveys conducted in the U.
The YRBS and the BRFSS ask high school students and adults respectively, about health-related behaviors such as substance use, nutrition, sexual behavior, and physical activity. Results from these surveillance systems can be used to monitor trends in health behaviors, plan public health programs, and evaluate public health policies at national and state levels.
This is a population-based surveillance that involves collecting data from a sample of reporting sites sometimes called sentinel sites. For example, one of the most common sentinel surveillance systems used in the United States is for influenza. Selected health care providers report the number of cases of influenza-like illness to their state health department on a weekly basis.
This surveillance allows states to monitor trends using a relatively small amount of information. Zoonotic surveillance system diseases found in animals that can be transmitted to humans involves a system for detecting infected animals.
Mosquitoes and blood were collected and tested for WNV in 10 counties. In addition, veterinarians were asked to test horses with neurologic symptoms consistent with WNV. Health care providers were reminded of reporting and diagnostic criteria for possible human cases of WNV Blackmore As a result, detection of WNV led to public health control measures, such as advising the public to protect against mosquito bites and intensifying mosquito abatement efforts. The purpose of this system is to gather information about negative effects experienced by people who have received approved drugs and other therapeutic agents.
Reports came from health care providers, including physicians, pharmacists, and nurses, as well as members of the general public, such as patients or lawyers, and manufacturers.
