DATA IDENTIFICATION


Name
Prevalence of anaemia in women aged 15-49, by pregnancy status (%)
Indicator purpose

The anaemia prevalence for the population is used to classify the public health significance of the problem.

Abstract

Percentage of women aged 15−49 years with a haemoglobin concentration less than 120 g/L for nonpregnant women and lactating women, and less than 110 g/L for pregnant women, adjusted for altitude and smoking.

Other characteristics

Anaemia is highly prevalent globally, disproportionately affecting children and women of reproductive age. It negatively affects cognitive and motor development and work capacity, and among pregnant women iron deficiency anaemia are associated with adverse reproductive outcomes, including preterm delivery, low-birth-weight infants, and decreased iron stores for the baby, which may lead to impaired development. Iron deficiency is considered the most common cause of anaemia, but there are other nutritional and non-nutritional causes. Blood haemoglobin concentrations are affected by many factors, including altitude (metres above sea level), smoking, trimester of pregnancy, age and sex. Anaemia can be assessed by measuring blood haemoglobin, and when used in combination with other indicators of iron status, blood haemoglobin provides information about the severity of iron deficiency.

DATA CONCEPTS and CLASSIFICATIONS



Classification used

Anaemia: a condition in which the concentration of blood haemoglobin falls below established cut-off values.

Iron deficiency state in which there is insufficient iron to maintain the normal physiological function of blood, brain and muscles (ICD-11, 5B5K.0 iron deficiency).

Iron deficiency anaemia: (ICD-11, 3A00, iron deficiency anaemia)

Blood haemoglobin concentration: concentration of haemoglobin in whole blood.

Disaggregation

is by pregnancy status (%). 

Key statistical concepts

The anaemia status of women is assessed using blood haemoglobin concentrations. In surveys, blood haemoglobin concentrations are typically measured using the direct cyanmethemoglobin method in a laboratory or with a portable, battery-operated, haemoglobin photometer in the field that uses the azide-methaemoglobin method.

Limitations

Data for blood haemoglobin concentrations are still limited, compared to other nutritional indicators such as child anthropometry. 

Additionally, it was not possible to incorporate into the analyses of some potentially important predictors of blood haemoglobin concentration, especially dietary iron and iron supplementation, because of limited data.
