Global Health Observatory (GHO) data repository. Prevalence cut-off values for public health significance Overall, the most vulnerable, poorest and least educated groups are disproportionately affected by iron-deficiency anaemia.Ĭut-off values for public health significance Population groups with greater iron requirements, such as growing children and pregnant women, are particularly at risk. The main risk factors for iron-deficiency anaemia include a low dietary intake of iron or poor absorption of iron from diets rich in phytates or phenolic compounds. Malaria, HIV/AIDS, hookworm infestation, schistosomiasis and other infections such as tuberculosis contribute to the high prevalence of anaemia in some areas. Resource-poor areas are often more heavily affected because of the prevalence of infectious diseases. Anaemia is a global problem affecting all countries. In addition, the negative consequences of iron-deficiency anaemia on the cognitive and physical development of children and on physical performance – particularly the work productivity of adults – are major concerns. Iron-deficiency anaemia reduces the work capacity of individuals and entire populations, with serious consequences for the economy and national development. What are the consequences and implications?Īnaemia is associated with increased risks for maternal and child mortality. The test could be easily integrated into regular health or prenatal visits or household surveys, to capture women of reproductive age, although the cost of the equipment and regular calibration needs to be taken into account.

A few drops of blood obtained by a finger-stick can be used to assess haemoglobin concentrations in the field using a portable haemoglobinometer. Tests to measure haemoglobin levels are easy to administer. WHO defines anaemia in children aged under 5 years and pregnant women as a haemoglobin concentration <110 g/L at sea level, and anaemia in non-pregnant women as a haemoglobin concentration <120 g/L. Anaemia in women of reproductive age and in children are also included in the WHO Global reference list of 100 core health indicators.Īnaemia is defined as a haemoglobin concentration below a specified cut-off point that cut-off point depends on the age, gender, physiological status, smoking habits and altitude at which the population being assessed lives. These indicators are used to monitor progress towards achieving Global Nutrition Target 2, which is a 50% reduction in anaemia among women of reproductive age by 2025. The terms “iron-deficiency anaemia” and “anaemia” are often used synonymously also, the prevalence of anaemia has often been used as a proxy for iron-deficiency anaemia, although the degree of overlap between the two varies considerably from one population to another, according to gender and age.Īnaemia prevalence among pregnant and non-pregnant women are included as primary outcome indicators in the core set of indicators for the Global Nutrition Monitoring Framework. malaria and other infections, genetic disorders, and cancer) can also play a role in anaemia. Iron deficiency is considered to be the most common cause of anaemia other causes include acute and chronic infections that result in inflammation and blood loss deficiencies of other vitamins and minerals, especially folate, vitamin B12 and vitamin A and genetically inherited traits, such as thalassaemia.
The indicator anaemia has a wide variety of causes.
