Background Acute malnutrition is a major global public health problem, particularly in low and middle-income countries. A targeted supplementary feeding program is an approach recommended to address moderate acute malnutrition in food insecure settings. Preventing and treating moderate acute malnutrition requires identifying factors shown to affect the treatment outcome and duration of stay on treatment. This study aimed to determine the treatment outcome and predictors of recovery time from moderate acute malnutrition among children 6–59 months of age in Darolebu district, Eastern Ethiopia. Methods A retrospective cohort study design was conducted on 540 children with moderate acute malnutrition. A Kaplan–Meier survival analysis was used to estimate the recovery time. Cox proportional hazard regression model was used to determine the association between the independent and the outcome variables. The proportional hazard assumption of the model was checked graphically and statistically. Any violation of the proportional hazard assumption of the model was also considered and adjusted in the analysis. Finally, a variable with a P-value <0.05 in the multivariate cox regression model was considered statistically significant. Results The overall recovery rate was 73% (95% CI 69.4–76.4%) with the median time to recovery of 16 weeks. Being between the ages of 24 and 59 months (AHR = 1.24, 95% CI: 1.01–1.54), having a mid-upper arm circumference (MUAC) at admission between 11.5 and 11.9 cm (AHR = 1.27, 95% CI: 1.34–2.61), walking for an hour or less to receive services (AHR = 1.2, 95% CI: 1.02–1.89), using ready-to-use supplementary food (AHR= 1.8, 95%CI: 1.38–2.39) were significant predictors of recovery time. Conclusion The recovery rate was slightly below the accepted minimum international standard, suggesting that further work is needed to improve the treatment outcomes and mortality and morbidity associated with moderate acute malnutrition.
