Iron-rich food consumption and associated factors among children aged 6-23 months in sub-Saharan Africa: A multilevel analysis of Demographic and Health Surveys

Abstract

Introduction Anemia remains a major public health problem for children in sub-Saharan Africa (SSA). Iron-rich foods consumption has a determinant role on the anemia status. Hence, this study aimed to determine the prevalence of good consumption of iron-rich foods and its associated factors among children aged 6-23 months in SSA. Materials and methods The recent Demographic and Health Survey data sets of thirty-five SSA countries were used. Data were analyzed using STATA/MP version 16.0 and all statistical analyses were done after weighting the data. A generalized linear mixed model using Poisson regression with robust error variance was used to determine factors associated with good consumption of iron-rich food. Association of variables was declared at a p-value of .0.05 and adjusted prevalence ratio (aPR) ratio with its 95% confidence interval (CI) was calculated for each variable. Results The total weighted samples of 77,001 children aged 6-23 months were included. The prevalence of consumption of iron rich foods was 42.1% (95% CI: 41.78-42.48). Children with age of 12-17 (adjusted prevalence ratio (aPR) = 1.96, 95% CI: 1.89-2.04) and 18-23 months (aPR = 2.05, 95% CI: 1.97-2.14), who took drugs for intestinal parasites (aPR = 1.30, 95% CI: 1.26-1.34), with postnatal check within 2 months (aPR = 1.09, 95% CI: 1.06-1.13), and children from women with ANC visit of 1-3 (aPR = 1.31, 95% CI: 1.24- 1.37) and ≥4 (aPR = 1.41, 95% CI: 1.34-1.48) had higher prevalence of good consumption of iron rich foods. Moreover, the prevalence of consumptions of iron rich foods was higher among children from; family with rich (aPR = 1.36, 95%CI: 1.30-1.42) and middle (aPR = 1.14 95% CI: 1.09-1.19) wealth index, and mother with media exposure (aPR = 1.26, 95% CI: 1.22-1.31). Conclusion The prevalence of good consumption of iron-rich foods among children aged 6-23 months in SSA countries is low. Child factors, family factors, and community-level factors were significantly associated with consumption of iron rich foods. Strategies to increase the consumption of iron-rich foods during this critical stage of growth and development should be designed in SSA.
