Abbreviated Name:
Anaemia prevalence in women of reproductive age
Indicator Name:
Anaemia prevalence in women of reproductive age
Domain:
Health determinants and risks / Risk factors
Related Terms:
Nutritional disorders
Definition:
Percentage of women aged 15-49 years with a haemoglobin level less than 120g/L for non-pregnant women and lactating women, and less than 110g/L for pregnant women, adjusted for altitude and smoking
Measurment Method:
The anaemia status of women is assessed using blood haemoglobin concentrations. Blood haemoglobin concentrations are typically measured in surveys using the direct cyanmethemoglobin method in a laboratory or with a portable, battery-operated, haemoglobin photometer (using the azide-methaemoglobin method) in the field.
Numerator:
Number of women aged 15-49 years with haemoglobin levels below the indicated cut-off, adjusted for altitude and smoking
Denominator
Total number of women aged 15-49 years with haemoglobin levels assessed during a specified period.
Estimation method:
Data on the prevalence of anaemia and/or mean haemoglobin in women of reproductive age, collected between 1995 and 2019 were obtained from 408 population-representative data sources from 124 countries worldwide. A Bayesian hierarchical mixture model was used to estimate haemoglobin distributions and systematically address missing data, non-linear time trends, and representativeness of data sources.
