PrEP Intervention in Prince George's County, Maryland

Официальное название

A Community-based Intervention to Increase PrEP Initiation in Prince George's County, Maryland: Reducing HIV Stigma and Increasing Social Support

Обзор

The goal of the proposed research is to design a peer-based community intervention focused on addressing HIV stigma, and peer support to increase PrEP initiation in Prince George's County, MD. Participants will attend intervention events focused on stigma reduction and building community. Researchers will compare intervention and control group participants to see if there in a difference in PrEP initiation and adherence.

Подробное описание

Black gay, bisexual, and other Black sexual minority men (BSMM) are a priority population and experience the highest rate of new HIV infections in the United States. Maryland (MD) is an HIV epicenter and ranks 4th in AIDS cases nationally; the state has several hotspots of HIV and AIDS cases in geographically distinct areas, including urban, suburban, and rural settings. Prince George's (PG) County is a majority Black suburban county (63% Black) bordering Washington, DC, with the highest per capita income for Black people in the nation, yet the second highest incidence and prevalence of HIV in the DC greater metropolitan area. It is an understudied region in the "Ending the Epidemic" initiative to end HIV in the United States. Despite the availability of PrEP for prevention and overall economic resources in this area, uptake among BSMM remains low. Greater understanding of factors impacting PrEP utilization among BSMM in this population and region of the U.S. are necessary for successful HIV prevention for BSMM. Additionally, extant literature specific to PrEP use in PG county is extremely limited.

Internalized stigma is an important and understudied factor that can deter PrEP use among BSMM, similar to the well documented associations between internalized stigma and several HIV risk behaviors among SMM. Research has consistently shown the impact of stigma on several HIV-related outcomes among SMM, including HIV stigma that deters uptake of HIV prevention. In contrast, social support can facilitate HIV prevention behaviors. Internalized stigma and peer social support are potentially modifiable factors that may directly impact PrEP acceptability and PrEP stigma; the associations between internalized stigma and PrEP use are still notably understudied. Despite this, interventions promoting PrEP use have largely not addressed internalized stigma as a potential barrier to uptake.

The goal of the proposed research is to design a peer-based community intervention focused on addressing HIV stigma, HIV knowledge, and peer BSMM support to increase PrEP initiation in Prince George's County, MD. The investigators will adapt the MPowerment peer-based model: This is a CDC-developed evidence-based intervention originally designed to reduce sexual risk and improve peer support through the use of peer-led activities and discussions, often in a drop-in center. There have been several successful adaptations of the MPowerment model in different settings. The investigators are adapting the model to focus on improving PrEP initiation through focusing on peer support, and reducing internalized stigma, including HIV stigma, through peer-led events and activities. The following are our aims:

Aim 1. Using ethnographic methods (participant and direct observation), study peer-peer interactions/exchanges and HIV prevention communications in two ongoing MPowerment programs, one in Falls Church, VA (suburban) and the other in Washington, DC (urban).

Aim 2. Conduct 32 in depth interviews to inform adapting an MPowerment intervention to reduce internalized stigma and increase PrEP uptake among BSMM in PG County. This would inform intervention site selection, promotion materials, and design of events and activities.

Aim 3. Pilot test a community-based pretest-posttest intervention (n=130) to increase PrEP uptake in PG County, based on the MPowerment model, with a focus on reducing internalized HIV stigma and increasing social support and resilience.

Вмешательства

• Поведенческое MPowerment PrEP Promotion Intervention
  In-person events will focus on five specific goals: Fostering a sense of community acceptance and social connection, promoting self-acceptance of sexual identity, teaching skills for navigating healthcare, reducing PrEP stigma, and providing education on HIV risk. In accordance with the MPowerment model, In collaboration with the PI, the core group and volunteers would lead the development, implementation, and evaluation of all intervention events. Both peer leaders and the primary investigator
