Background: Nearly 20 million under-five children are affected by severe acute malnutrition rnworldwide. In Africa, more than 14.0 million under-5 children are wasted, of which 4.1rnmillion children are severely wasted. Ethiopia is one of the countries with highest under-fivernchild mortality rate, with malnutrition underlying to 28% of all children deaths.rnAccording to world health organization and the SPHERE project, at least 75% of childrenrnadmitted due to SAM should be recovered and they should be recovered in less than or equalrnto 28 days. rnObjective: The main objective of this study was to assess recovery time from severe acuternmalnutrition and associated factors among under-5 children admitted and treated in Yekatit 12rnHospital.rn Method: A retrospective cohort study was conducted in Yekatit 12 hospital. The studyrnpopulation was under-5 children with severe acute malnutrition who have been managed atrnYekatit 12 hospital therapeutic feeding unit. The total sample size was 423 and quantitativernpretested data abstraction format was used. Kaplan Meier analysis was used to estimate time tornnutritional recovery; Log rank was used to test whether the observed difference of recoveryrntime between different groups of predictor variables is significant or not; and Coxrnproportional-hazard regression analysis was carried out to determine independent predictors.rnResult: The nutritional recovery rate was 81.3% and the median recovery time was 15 daysrn(95% CI: 13.608-16.392). By controlling other factors, age, daily weight gain per Kg,rnvaccination status, comorbidities like pneumonia, stunting, shock, and deworming werernsignificant predictors of nutritional recovery time.rnConclusion:rnIn conclusion, the overall death rate in this study is poor compared to sphere project referencernvalue. However, recovery rate, default rate and nutritional recovery time were in thernacceptable range of SHHERE project reference value. Daily Wt gain of ≥8g/Kg, fullrnvaccination, and deworming with albendazole/mebendazole were proven to reduce nutritionalrnrecovery time. Conversely, older age, the presence of pneumonia, the presence of stunting, andrnthe presence of shock as comorbidities were proven to increase nutritional recovery time.
