Abstract: Background: Maternal HIV infection is known to be associated with adverse pregnancy outcomes, including low birth weight (LBW) and perinatal mortality, based on several studies. However, the conflicting effect of antiretroviral therapy (ART) on these outcomes has not been thoroughly examined. Understanding this association is crucial for guiding policy makers in developing more effective interventions to prevent mother-to-child HIV transmission. The study aimed to assess the effect of maternal HIV infection on birth weight and perinatal mortality, as well as investigate the impact of ART on these outcomes in HIV-infected women. To address possible confounders, matching methods were employed. Method: In this study, we analyzed the effect of HIV infection on maternal health, birth outcomes, and infant health using two contemporary cohorts of pregnant women: HIV-uninfected and HIV-infected. Search and Selection: Findings consistently indicated that infants born to HIV-positive mothers face increased risks, emphasizing the need for urgent attention to improve neonatal health. Results: A total of 12 articles were critically appraised for this review. The articles were categorized into research (n=9) and non-research (n=3) articles. Each article was scored using the John Hopkins critical appraisal tools for research and non-research evidence, respectively. The scoring was calculated by dividing the number of correct answers by the total number of answers and multiplying by 100. Out of the 12 articles, 11 scored above 60%, meeting the cut-off of 55%, while one article scored 58%. All 12 articles met the inclusion criteria. Key findings included: - Antiretroviral therapy (ART) emerged as a crucial intervention in reducing the risk of adverse outcomes. - Implementing expanded access to ART and routine prenatal HIV testing can identify and treat HIVpositive pregnant women, minimizing mother-to-child transmission during childbirth. - Despite efforts to promote testing and treatment, a significant proportion of HIV-positive pregnant women remain undetected, highlighting the need for enhanced screening programs. - Improved obstetric care plays a vital role in optimizing neonatal outcomes, reducing complications during childbirth and positively impacting both maternal and neonatal health. Discussion: The interventions mentioned aim to ensure that newborns have a healthy start, free from the adverse effects of maternal HIV infection. The study's findings underscore the importance of understanding the impact of maternal HIV infection on neonatal outcomes and advocate for comprehensive strategies to enhance neonatal health. Public health interventions should prioritize expanded access to ART, routine prenatal HIV testing, and improved obstetric care to mitigate the adverse effects of maternal HIV infection on newborns. By addressing these factors, we can contribute to improved maternal and child health outcomes, reducing the burden of adverse pregnancy outcomes, and promoting the overall well-being of neonates. Conclusion: In conclusion, our review emphasizes the significance of understanding the impact of maternal HIV infection on neonatal outcomes. Through the implementation of expanded access to ART, routine prenatal HIV testing, and improved obstetric care, we can mitigate the adverse effects of maternal HIV infection on newborns and enhance overall neonatal health. These findings hold important implications for public health interventions aimed at improving maternal and child health outcomes.
