Factors associated with childhood underweight among orphaned preschool children: A community-based analytical cross-sectional study in Southern Ethiopia

BACKGROUND: Childhood underweight is one of the major public health problems in Ethiopia. In Ethiopia, most of the available evidence is related to the general community children, which had different risk and severity levels than orphan children. Even though under-five orphan children have a higher risk of being underweight, they are the most neglected population. OBJECTIVE: The study aims to determine the prevalence and factors associated with childhood underweight among orphaned preschool children in Southern Ethiopia. METHODS: A community-based analytical cross-sectional study was conducted among 367 orphans. The burden of childhood underweight was assessed using World Health Organization standard cutoff points below −2 SD using z-scores. All variables with a p-value of < 0.25 during binary logistic regression analysis were entered into a multivariate logistic regression analysis to identify predictor variables independently associated with underweight at a p-value of 0.05 with 95% CI. RESULTS: In this study, the prevalence of underweight among orphan children was 27.4%. The main factors associated with underweight were female child (adjusted odds ratio (aOR) = 5.29, 95% confidence interval (CI) (2.83–9.92)), adult food as type of first complementary food (aOR = 2.47; 95% CI (1.24–4.94)), food insecurity (aOR = 1.98; 95% CI (1.23–3.21)), and child age from 24–59 months (aOR = 7.19; 95% CI (3.81–13.60)). CONCLUSION: Childhood underweight is a public health problem in the study area. The sex of a child, type of first complementary food, household food security status, and child age were the major predictors of underweight. Therefore, appropriate dietary interventions, nutrition education, and increased food security status of orphan children are highly recommended.
