Insights
Severe acute malnutrition stabilization in Ethiopian children took a median of 11 days, longer than recommended. Key predictors include immunization status, pneumonia, hospital infections, and vitamin A supplementation, highlighting areas for intervention to improve outcomes.
Area of Science:
- Pediatrics
- Public Health
- Infectious Diseases
Background:
- Over 65% of deaths from complicated severe acute malnutrition (SAM) occur within the first week of treatment due to medical complications.
- Early stabilization is critical for reducing mortality in SAM cases, but evidence on optimal stabilization time in Ethiopia is limited.
Purpose of the Study:
- To assess predictors of time to stabilization among under-five children admitted with severe acute malnutrition (SAM) to stabilization centers in Ethiopia.
Main Methods:
- A retrospective follow-up study analyzed data from 543 children admitted to hospitals in Western Oromia between January 2020 and December 2024.
- Statistical analysis involved Kaplan-Meier curves, log-rank tests, and multivariable Weibull regression to identify predictors of stabilization time.
- Data were collected using kobotoolbox and analyzed using STATA version 17.
Main Results:
- The median time to stabilization from severe acute malnutrition (SAM) was 11 days, with an 86.39% stabilization rate.
- Predictors of stabilization time included immunization status (protective), pneumonia (increased time), hospital-acquired infections (increased time), and vitamin A supplementation (protective).
Conclusions:
- The study identified a median stabilization time of 11 days for severe acute malnutrition (SAM), which is longer than the Ethiopian national protocol recommends.
- Addressing predictors such as immunization status, pneumonia, hospital-acquired infections, and vitamin A supplementation is crucial for health professionals and stakeholders to achieve quicker stabilization.
Background:
Due to their fragile physiologic functions, Over 65% of deaths from complicated severe acute malnutrition occur in the first week of treatment, primarily due to medical complications. To reduce this, early stabilization is crucial, and there is limited evidence regarding stabilization time in Ethiopia.
Objective:
To assess predictors of time to stabilization among under-five children admitted with severe acute malnutrition to stabilization centers in Ethiopia.
Method:
A retrospective follow up study was conducted from January 20 to February 29, 2025 on 543 sampled children selected by a simple random sampling from severely malnourished children admitted to selected hospitals in Western Oromia between January 2020 and December 2024. After collecting data using kobotoolbox, it was exported to STATA version 17 for analysis. Kaplan Meier curve and log-rank test were used to estimate the stabilization rate and presence of statistically significant difference in survival and hazard rate between categories of explanatory variables. Proportional hazard assumption was checked using schoenfeld residual test and log-log survival curve. After performing model comparison, the Weibull model was selected and variables with p < 0.25 on bi-variable regression was selected for multivariable weibull regression. Estimating adjusted hazard ratio with their respective 95% confidence interval, P-value of less than 0.05 was used to declare statistically significant association with stabilizing time.
Result:
Over 5600 child-days of observation, the median time to stabilize from severe acute malnutrition was 11 days, with 86.39% rate of stabilization and 86.6/1000 incidence of stabilization (95% CI: (74.45-89.44)). Immunization status (AHR: 0.66, 95% CI (0.54-0.8)), pneumonia (AHR: 2.17, 95% CI (1.74-2.70)), hospital acquired infections (AHR: 1.34 95% CI (1.09-1.65)) and vitamin A supplementation (AHR: 0.61, 95%CI (0.49-0.77)) were predictors of stabilization time.
Conclusion:
This study found prolonged time to stabilization of 11 days compared to the recommendation of Ethiopian national management protocol of severe acute malnutrition. To achieve quicker stabilization, health professionals, hospital managers, and all stakeholders must collaboratively address and reduce the burdens stemming from identified predictors.
