Technical Note: Age-adjustment of child anthropometry estimates

Background: The standard age group for reporting prevalence estimates of child nutritional status is 0 – 59 months (children under five years of age). However, many national household surveys, including Demographic and Health Surveys (DHS) in the earlier 1990s, only collected anthropometry information for children under three years of age or under four years of age, thus making the reported estimates non‐standard and incomparable with estimates of children under five years of age. Such estimates are included in UNICEF global database of child anthropometry and reported as is in the annual State of World’s Children (SOWC) publications. In addition, these estimates are age‐adjusted to represent children under five so that they are comparable and included in any country and regional trend analysis.
