Abstract

Background & Aim: Under-nutrition is the underlying cause of child morbidity and mortality in Nigeria, accounting for more than 50% of deaths among under-five year old children. This study examined socioeconomic-related inequalities in child under-nutrition in Nigeria using the decomposition approach. Methods: The study analyzed data from the Nigeria Demographic and Health Survey (NDHS) 2003 to 2013. Trends in child under-nutrition were examined against socioeconomic factors. The outcome variables were stunting (HAZ<2 SD), wasting (WHZ<2 SD) and underweight (WAZ<2 SD) among children 0-59 months. The magnitude of child under-nutrition was estimated via a concentration index, and the inequality was decomposed to ascertain the contribution of socioeconomic factors to child under-nutrition over time. Results: Socioeconomic inequality in child under-nutrition increased between 2003 and 2013. The decomposition of the concentration index showed that the consistent contributing factors to the increase in socio-economic inequalities in child under-nutrition were: Child�s age (0-23 months), maternal education (no education), household wealth index (poorest household), type of residence (rural) and geopolitical zone (North East, North West). Conclusions: This result suggests the need for a multifaceted nutrition intervention that involves improving maternal education and the adoption of social protection policies, to reduce inequalities in child under-nutrition especially among socioeconomically disadvantaged groups in Nigeria. This would set the country on its path to achieving the post-2015 sustainable development goals of improving children�s health.
