About
Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV infection but requires high levels of medication adherence, particularly among women. The purpose of this proposal is to evaluate the clinical impact and mechanisms of a family-based storytelling intervention (vs. couples counseling) to improve PrEP adherence and retention among at-risk pregnant/lactating women and their HIV-infected male partners in rural Mozambique. This potentially high impact intervention provides the opportunity to test a culturally relevant approach to PrEP engagement; if proven feasible and effective, family-based storytelling for PrEP engagement could be adopted to reduce HIV incidence among pregnant/lactating women and eliminate mother-to-child transmission (MTCT).
Full description
Project Summary: Pregnancy and the postpartum period are associated with an increased risk of HIV acquisition. HIV acquisition is of particular concern during pregnancy and while the mother is breastfeeding given the associated increased risk of mother-to-child transmission (MTCT). Approximately 10% of pregnant women attending antenatal care (ANC) in Mozambique are in serodiscordant relationships (HIV-negative woman/ HIV-positive man). High rates of MTCT (14%; 12,000 infants/ year) may be affected by the high rate at which pregnant women seroconvert after their first ANC visit. Beginning in 2018, pre-exposure prophylaxis (PrEP) was available to serodiscordant couples, yet only 44% of pregnant women were retained in care at 3 months.
Our current R01-funded project, Partners-based HIV Treatment for Seroconcordant Couples (R01MH113478), is testing a couple-based intervention for HIV-positive expectant parents living in extremely rural communities. Our Men for Health intervention ("Homens para Saúde+"- HoPS+) consists of (1) couple-based HIV care and treatment; (2) couple-centered education; and (3) expert-patient support. Preliminary data the HoPS+ study suggest that couple-based counseling and education is more successful at reducing maternal depression than individual care. However, couple-based sessions have not led to significantly greater improvements in HIV knowledge or social support. Given the importance of these factors on treatment adherence, this grant would allow us to revise the peer engagement strategy to increase knowledge transfer and engender partner support.
The investigators propose testing the impact of a peer-delivered oral storytelling intervention to increase retention in, and adherence to, PrEP/ART among expectant serodiscordant couples. People are 7 times more likely to remember a story compared to facts alone. Couples are also highly influenced by their immediate and extended families; >95% of patients disclose their HIV status to members of their family. The investigators hypothesize that the use of oral storytelling will facilitate learning and encourage family support and advocacy. The investigator will compare this model to couple-based education and counseling. This innovative intervention tests a culturally relevant approach to improve ART/PrEP delivery. The investigators propose a rigorous individually randomized controlled trial at one of our current HoPS+ sites where 11% of expectant couples were serodiscordant in 2018. The investigators will randomize 70 HIV-uninfected pregnant women and 70 of their HIV-infected partners (total 140) to either the intervention or control condition.
The Specific Aims of this study are: (1) Compare the effect of a storytelling intervention (vs. couples-based counseling) on participant knowledge, motivation, and behavioral skills associated with PrEP retention and adherence; and (2) Evaluate the impact of a storytelling intervention on adherence to PrEP/ART medications. Our team of Mozambican and U.S. investigators has a proven record of international HIV research success, specific recent experience with partner-based HIV and PrEP delivery, and experience with the use of theater/storytelling to change HIV-related behaviors.
