Prevalence of HIV infection and associated factors among infants born to HIV-positive mothers in health institutions, northwest Ethiopia, 2021

Abstract

Background: Mother-to-child transmission of the HIV remains the main source of HIV infection in children. Targeting pregnant women attending antenatal care follow-up provides a unique opportunity for implementing prevention of mother-to-child transmission programs against HIV infection in newborn babies. Objective: The objective of this study was to assess the prevalence of HIV infection and associated factors among infants born to HIV-positive mothers in the prevention of mother-to-child transmission clinic in the Gondar city health institutions, Northwest Ethiopia, 2021. Methods: Documents were reviewed at the facility. Infants who had been exposed to HIV were enrolled in the study from 1 May–20 June 2021 prevention of mother-to-child transmission service in Gondar health institutions. To collect data from the charts, a structured data extraction tool was developed. The data were entered and analyzed with SPSS version 25 software. Both bivariate and multivariate logistic regression models were fitted to identify factors associated with HIV infection. The crude and adjusted odds ratios with a 95% confidence interval were calculated to determine the significance level. Result: The prevalence of HIV infection among infants born to HIV-positive mothers at the prevention of mother-to-child transmission level was found to be 8.1% (95% confidence interval = 7.3–12.9). Mixed infant feeding practice (adjusted odds ratio = 5.15, 95% confidence interval = 1.82–14.56), mothers’ lack of education (adjusted odds ratio = 3.43, 95% confidence interval = 2.26–5.0), absence of antenatal care follow-up (adjusted odds ratio = 1.82, 95% confidence interval = 1.17–4.02), and home delivery (adjusted odds ratio = 2.24, 95% confidence interval = 2.10–7.45) were statistically significantly associated with infants’ HIV infection. Conclusion: The prevalence of HIV infection in babies born to HIV-positive mothers was found to be high. Significant factors include mixed infant feeding practice, mothers’ lack of education, antenatal care follow-up, and home delivery. We also proposed that skilled delivery care and community education could reduce HIV transmission from mother to child.
