jamii bora: a home-based couples intervention

Conditions: Human Immunodeficiency Virus

Summary: the purpose of the study is to develop and pilot-test a home-based intervention to facilitate sate hiv testing and disclosure within pregnant couples in order to increase use of prevention-of-mother-to-child-transmission (pmtct) and family health services in kenya.

despite the potential for anti-retroviral therapy (art) to ensure maternal health and reduce vertical hiv transmission to as low as 1%, hiv-related maternal deaths and hiv infection among infants remain unacceptably high across sub-saharan africa. prevention of mother-to-child transmission (pmtct) requires a complex series of interventions throughout pregnancy and after birth, and only an estimated 15-30% of eligible women complete this "pmtct cascade". drop-offs can occur in the pmtct cascade if women refuse hiv testing, do not disclose their hiv status, or avoid essential health services because they fear negative consequences for their relationship with their male partner. engaging both partners of a couple during pregnancy has the potential to enhance health decisions, increase healthcare utilization, and ultimately improve maternal, paternal, and infant health. the goal of this study is to develop and pilot a home-based couples intervention that includes safe hiv testing and disclosure for couples, alongside information and counseling for family health during the perinatal period. the investigators will adapt existing evidence-based couples hiv counseling and testing (chct) protocols for the special needs of pregnant women and their male partners, and train pairs of lay health workers (one female and one male) to deliver this service as part of home visits in rural kenya. as men rarely attend antenatal clinics in kenya, a home-based strategy can reach the couple in a safe and convenient space and give them unprecedented access to family health information, chct services, and linkage to care. this intervention, based on an interdependence model of communal coping and behavior change, is expected to help couples to communicate, plan, and take action around hiv and family health. building on our team's preliminary studies in this rural kenyan setting, the investigators collected further formative data and translated our findings into a viable intervention model with input from local stakeholders. the investigators will then conduct a pilot study of the home-based couples intervention, in which the investigators will randomize pregnant women at two antenatal clinics to the intervention or standard care arms of the study, and follow them and their male partners until three months after the expected delivery date of the baby. the investigators will preliminarily assess the effects of the intervention on uptake of chct by couples, repeat hiv testing during pregnancy for hiv-negative women, and utilization of pmtct and hiv services for hiv-positive women and men. the investigators will also explore the roles of potential mediators for these effects suggested by our interdependence conceptual framework (such as measures of couple relationship dynamics). results from this study will provide evidence of the preliminary impact, acceptability, and feasibility of the intervention and the study methods that will allow our team to develop a larger-scale efficacy trial. engaging pregnant couples in family health and pmtct is an essential step towards reducing hiv-related maternal mortality and eliminating new hiv infections among children in sub-saharan africa.
