Undernutrition and its determinants among children aged 6–59 months in Southern Ethiopia

Malnutrition is responsible for over one-third of deaths among children under the age of five in low-and middle-income countries, including Ethiopia, and is largely preventable. The objective of this study was to determine the prevalence of undernutrition and its contributing factors among children aged 6–59 months in the Gedio zone of Southern Ethiopia. A community-based cross-sectional study design was used, and data were collected from 403 children and their mothers selected through random sampling technique. Anthropometric measures were converted to Z-scores using WHO-Anthro version 3.2.2 software. The prevalence of underweight, wasting, and stunting were 19.7% (95% CI 16-24%), 10% (95% CI 7–13%), and 49% (95% CI 44–54%) respectively. Low birth weight (AOR = 2.8, 95% CI (1.585–4.895), feeding non-diversified diet (AOR = 1.9, 95% CI (1.036–3.497), and being unvaccinated (AOR: 2.0; 95%CI (1.013–4.197) were significantly associated with being underweight. Family size of ≥ 5 (AOR = 4.4, CI (1.274–5.059), meal frequency of
