The most common and severe cause of morbidity and mortality among HIV- positive children is opportunistic infections (OIs). All HIV-infected children are at risk of developing a variety of OIs. Healthcare workers, programmers, and other stakeholders are in doubt about using the onset and predictors of OIs among schoolchildren on antiretroviral therapy (ART) due to the presence of conflicting results found in the primary studies. Hence, this study was conducted to provide a single figure of onset and specific predictors of OIs by overcoming the existing heterogeneity in Ethiopia.
The included studies were searched from different national and international databases systematically. The included studies were cohort in design and published in English between 2015 and 2022. The data were extracted using a validated Microsoft Excel tool after the quality of the included studies was assured. The extracted data were exported to Stata Version 17.0 for further management and analysis. The presence of heterogeneity across studies was checked using the Chi-square test and quantified using the
Eleven studies were included in this systematic review and meta-analysis. The onset of OIs among schoolchildren on ART in Ethiopia was 5.58 (95% CI: 4.50, 6.67) per 100 children-years of OI-free observations. Those children who had no parents had a 1.41 (95% CI: 1.10, 1.80) times higher chance of getting OIs when compared with those children having one or both parents. Children who had poor ART adherence had a 2.96 (95% CI: 1.66, 5.29) times higher chance of experiencing OIs than children who had good ART adherence. Finally, the chance of experiencing OIs among rural children was 2.15 (95% CI: 1.63, 2.83) times higher than their counterparts in Ethiopia.
Three in every 33 schoolchildren on ART developed OIs in Ethiopia. Predictors of OIs included schoolchildren without parents, those with poor adherence to ART, and rural residents. This suggests that social support, medication adherence, and access to healthcare services may play important roles in preventing and controlling OIs among schoolchildren living with HIV in rural areas.
