Prevalence and patterns of anthropometric failure among under-five children in Nigeria: Evidence from the National nutrition and health survey, 2018.

Globally, malnutrition among under-five children remains a public health concern. There is increasing concern at research and policy levels about anthropometric failure and the double burden of child malnutrition across different groups of children. The objective of this study was to describe the magnitude and distribution of various forms of anthropometric failure (AF) among children under age five in Nigeria. We used the 2018 National Nutrition and Health Survey data collected among 19,471 under-five children in Nigeria. The most prevalent AF was stunting only (17.7%) followed by stunting and underweight (13.9%). Wasting, stunting and underweight was found among 3.5% of the sample. Wasting, stunting and underweight was most common in age 6-11 months (7.0%) and 12-23 months (6.9%). Overall, about 1 out of 5 under-five children has multiple anthropometric failure. The peak age group for multiple AFs was between six months and 35 months. Multiple AF was less likely among females compared to males (RR=0.74, CI: 0.69, 0.80). The risk of multiple AF was higher in both North East (RR=2.15, CI: 1.78, 2.59) and North West (RR=2.98, CI: 2.51, 3.55) relative to the North Central. In contrast, the risk was lesser in the South East (RR=0.75, CI: 0.59, 0.95) and other southern regions. The study showed that multiple anthropometric failure is a common problem among children in Nigeria. Programmes that will support prevention and early identification of different types of malnutrition among under-five children across States in Nigeria are recommended.
