Abstract
BACKGROUND: In the era of highly active antiretroviral therapy, vertical HIV transmission has been decreased. This may increase fertility desire of HIV infected women and an increasing number of HIV exposed infants as a result. A high probability of mortality among HIV exposed infants was reported across different countries. However, few studies are found on mortality of HIV exposed infants, in particular, no study was conducted before in the current study area. METHODS: Institution based retrospective cohort study from July 2013 to December 2017 was conducted. A total of 408 HIV exposed children were selected through simple random sampling technique. Data were extracted from registration book by using data extraction tool, which is adapted from the Ethiopian Federal Ministry of Health HIV exposed infant follow-up form. Kaplan-Meier survival curve was used to show the probability of mortality rate. Bivariable and multivariable cox regression models were used to identify predictors of mortality. RESULTS: Overall mortality rate was found to be 8.88 (95% CI: 6.36-12.36) per 100 child-year. Infant with death of at least one parent (AHR = 3.32; 95% CI: 1.503-7.32), non-exclusive breastfeeding (AHR = 0.10; 95% CI: 0.037-0.302), growth failure (AHR = 2.9; 95% CI: 1.09-8.09), presence of sign and symptom of HIV infection (AHR = 2.99; 95% CI: 1.33-6.74), and low birth weight (AHR = 2.6; 95% CI: 1.007-6.78) were found to be predictors of infant mortality. CONCLUSIONS: Mortality of HIV exposed infants was high in Ethiopia. Prevention of the occurrence of HIV infection symptom, growth failure, and low birth weight is essential and further treat early whenever they occurred. Still, behavioral change interventions on mother who practice non-exclusive breastfeeding are indicated. Especial care for orphan infants is required due to their nature of vulnerability to varieties of health problem.
