Facilitators and barriers to adherence to anti-retroviral treatment among pregnant or breastfeeding women living with HIV and perinatally infected infants: A scoping review

Abstract

In 2022, 54% of 1.5 million children (age 0-14) living with HIV had access to anti-retroviral medication (ART). Adherence to ART for pregnant or breastfeeding HIV + women is critical for maintaining their personal health and to prevent mother-to-child-transmission (MTCT). For HIV + infants, adherence is essential to establish early viremic control and is contingent on caregiver administration. We conducted a scoping review to systematically identify and categorize the influences on ART adherence for pregnant or breastfeeding HIV + women and their HIV + infants. We searched databases in June 2023 and employed the Social-Ecological Model (SEM) to organize facilitators and barriers to adherence referenced in published articles. All articles published before 2016 were excluded due to updated guidelines from WHO on MTCT and ART. Our analysis included 52 articles. 50/52 took place in Africa and used cross-sectional and mixed-methods design. Barriers to adherence for pregnant or breastfeeding HIV + women included maternal education, self-efficacy, social support, and social/economic context. Barriers to infant adherence included development, nutrition, age of treatment initiation, disclosure, and ART side effects. Additional facilitators and barriers to adherence are presented at family, extra-familial, and socio-cultural SEM levels. Stigma was the most salient barrier referenced across the entire continuum of HIV care and all SEM levels. This review revealed a dearth of literature focusing on HIV + infants who are dependent on their caregivers for ART adherence and lack of a standard adherence measure. We identified multi-leveled influences on adherence impacting both the mother and infant and are amenable to public health intervention.
