Associated factors of malnutrition status among children and adolescents living with HIV in Tanzania: Individual-level analysis and marginal effect estimation
This study aimed to identify individual-level factors that affect malnutrition outcomes among children and adolescents living with HIV/AIDS in Tanzania.
Methods
We used data from the National AIDS Control Programme. 70,102 participants aged 5 to 19 years attending care and treatment clinics between January to December 2021 were included. Nutritional assessments were performed by anthropometric measurement. Logistic regression models were used to evaluate risk factors. We further estimated marginal prevalence and adjusted predictions by marginal effects. Supplementary analysis assessed the accuracy of the final fitted model.
Results
Prevalence of malnutrition for stunting, underweight, wasting, and anthropometric failure (CIAF) were 36.0%, 28.9%, 13.0%, and 48.0%, respectively. Several individual-level factors were significant determinants of malnutrition. Boys, participants aged 15-19 years, those switched to second- or third-line antiretroviral therapy (ART), initiated ART at ages of 5-14 years, ART duration less than 3 years, and were in advanced stages of WHO HIV clinical status had increased adjusted odds ratios and marginal prevalence. The larger AUC values for all models implied importance of identified factors accounted for malnutrition.
Conclusions
On long-term ART, nutritional interventions should be context-specific guidelines to improve growth, especially at ART initiation, ART regimen, and ART duration reckoning with age and sex.
