RESUMEN

Children who are HIV-exposed and uninfected (CHEU) are at increased risk for poor growth, health, and development compared to children who are HIV-unexposed and uninfected. To support families with CHEU, we assessed the acceptability of engaging family members to support women living with HIV (WLWH) with exclusive breastfeeding (EBF) and antiretroviral therapy (ART) adherence and to engage in responsive infant caregiving. We conducted trials of improved practices, a consultative research approach, that follows participants over time as they try recommended behaviors. We enrolled postpartum women in Lusaka, Zambia, who identified home supporters. At visit 1, WLWH were interviewed about current practices. At visit 2, WLWH and home supporters received tailored EBF, responsive care, and ART adherence counseling. At visit 3, WLWH and home supporters were interviewed about their experiences trying recommended practices for 2-3 weeks. Interview transcripts were analyzed thematically. Participants included 23 WLWH, 15 male partners, and 8 female family members. WLWH reported several barriers to EBF. The most common were fear of HIV transmission via breastfeeding-despite high ART adherence-and insufficient breastmilk. After counseling, WLWH reported less fear of HIV transmission and improved breastfeeding practices. Home supporters reported providing WLWH increased support for EBF and ART adherence and practicing responsive caregiving. Both male and female home supporters appreciated being included in counseling and more involved in caregiving, and WLWH valued the increased support. Families with CHEU need focused support. Tailored counseling and family support for WLWH show promise for improving EBF, responsive caregiving, and ART adherence.
