Association of Socioeconomic Status With Childhood Anemia Among Infant, Toddler, and Preschool Children in Bangladesh

Abstract

ObjectivesThis study aims to delineate the association between economic inequality, along with other confounders, and anemia among infants, toddlers, and preschool children. MethodsFrom the 2011 Bangladesh Demographic Health Survey, a cross-sectional population sample comprising 2068 children between ages 6 and 59 months were selected for this study. Analyses were performed with a proportional odds model and finally stratified with the child age groups. ResultsInfants belonging to a low and medium socioeconomic status (SES) have approximately a 3-fold higher chance of being affected by mild, moderate, or severe anemia compared with infants of high SES (odds ratio [OR] 2.94; 95% CI 1.09-7.91; P=.03 and OR 2.76; 95% CI .87-8.82; P=.08, respectively). Preschool children from low and medium SES households are 2.73× (95% CI 1.20-6.18; P=.02) and 2.47× (95% CI .99-6.14; P=.04) more likely to be anemic compared with their counterparts from higher SES households. The place of residence and childhood stunting are associated with childhood anemia (urban vs rural: OR 1.27; 95% CI .21-.35; P = .04; and stunted vs normal: OR 1.34; 95% CI 1.11-1.63; P = .003). Besides, vitamin A supplementations appear to serve as protective agents against the occurrence of the childhood anemia (OR 1.18; 95% CI .99-1.41; P = .06). ConclusionUrgent preventive measures are needed to control the impending childhood anemia among infants and preschool children, especially in the low and medium SES households (ClinicalTrials.gov Identifier: NCT03126253).
