Chronic Undernutrition and Associated Factors Among Children Aged 6 to 59 Months in South Ari, South Omo Zone, Ethiopia: A Community-Based Cross-Sectional Study.

Background: Chronic undernutrition (stunting) among children is associated with an increased risk of morbidity and mortality. The global community is committed to end all forms of malnutrition by 2030. Regardless of this, children are suffering from some form of malnutrition but the reason is unclear. This study thus was intended to identify stunting and associated factors among children aged 6 to 59 months in the South Ari Woreda of South Omo Zone.

Methods: A community-based cross-sectional study was conducted in South Ari Woreda from 1, January 2022 to 30, February 2022, and 409 children participated. A simple random sampling technique was used to identify study participants, and mothers/caregivers were interviewed. Data on sociodemographic, economic, and environmental determinants were collected by trained professional nurses using interviewer-administered questionnaires and anthropometric data were collected via weighting and measuring the height/length of the child. Emergency Nutrition Assessment for Standardized Monitoring and Assessment of Relief and Transitions 2020 software was used to generate an anthropometric index, and a child with a height for age index below -2standard deviations of the standard population was considered stunted. Factors of stunting were assessed using multivariate binary logistic regression at a 5% significance level.

Results: The study revealed that 44.0% (95% confidence interval (CI) = 39.19%-48.81%) of children were stunted in the study area. Household's wealth status (the poorest; adjusted odds ratio (AOR) = 4.14 [95% CI = 2.08-8.22] and poor; AOR = 3.31 [95% CI = 1.60-6.82]), improper solid waste management practice of the household (AOR = 2.67 [95% CI = 1.56-4.55]), and the children sleeping under insecticide-treated bed nets (ITN) (AOR = 0.37 [95%CI = 0.22-0.60]) were statistically significantly associated with stunting status of the children.

Conclusion: Stunting among the children in the study area was very high. Improving household's (HH) economy, safe management of domestic solid waste, and ensuring that the children are sleeping under ITNs are expected to reduce stunting.
