Time to nutritional recovery and its determinants among children aged 6 to 59 months with severe acute malnutrition admitted to stabilization centers of WagHimra Zone, Northeast Ethiopia

Severe acute malnutrition is a life-threatening condition that contributes to over half of under five deaths in developing countries. Urgent and specialized treatment to improve the time to recovery and recovery rate is very important. However, data regarding time to nutritional recovery is limited in Ethiopia. Hence, this study aimed to determine the average time to recovery and its determinants among children aged 6 to 59 months admitted with SAM to the stabilization centers of Wag Himra zone, northeast Ethiopia. A retrospective cohort study was conducted on 501 patients charts of children with severe acute malnutrition (SAM) admitted to stabilization centers (SCs) from September 2014 to August 2017. The charts were selected using the systematic random sampling technique. Data were extracted from the charts of each child using a pretested standard checklist and entered using Epi data version 3.1 and analyzed by STATA 14. A Cox proportional-hazard regression analysis was carried out to identify determinants of time to recovery. Any statistical test was considered significant at P-values < 0.05. In this study, the overall recovery rate from SAM was 80.4% (95% Confidence Interval [CI]: 76, 84) with the median nutritional recovery time of 11 (Inter Quartile Range [IQR]: 8-18) days. Patients aged 6-23 months (Adjusted Hazard Ratio [AHR] = 0.74, 95%CI: 0.60, 0.92), and had pneumonia (AHR = 0.44; 95% CI: 0.32, 0.59), anemia (AHR = 0.65; 95% CI: 0.52, 0.81) and vomiting (AHR = 0.63, 95% CI: 0.49, 0.82) at admission were less likely to recover quickly compared to those who did not have these conditions or were in other age categories, whereas edematous malnourished children (AHR = 2.85; 95% CI: 2.28, 3.56) were positively and significantly associated with early recovery. The median nutritional recovery time fell within the recommended international standards. However, the length of stay was significantly longer among children with severe wasting, aged 6-23 months, and had vomiting, pneumonia, and anemia at admission than their counterparts. Therefore, interventions should focus on young children with severe wasting, pneumonia, vomiting, and anemia to prevent prolonged stay in the SCs without recovery. Retrospectively registered
