Community Engagement for Effective Recruitment of Black Men at Risk for Hypertension: Baseline Data From the...

Black men are underrepresented in hypertension trials, even though this population has higher prevalence and more adverse sequelae from hypertension, compared to other groups. In this article, we present recruitment and community engagement strategies for the Community-to-Clinic Linkage Implementation Program (CLIP), a cluster-randomized trial on hypertension prevention among Black men.

Using a 2-stage recruitment process, (i) we enrolled Black-owned barbershops from zip codes with high hypertension prevalence and (ii) recruited Black male participants who fulfilled the eligibility criteria and were customers of the barbershops. Barbershop and participant recruitment was conducted by a partner community-based organization.

The study met the recruitment goals for barbershop enrollment (N = 22) and individual participants. Of eligible individuals (N = 461), 430 enrolled in the study (93% consent rate, exceeding the original enrollment goal of N = 420 participants). Throughout recruitment, the study team conducted 101 unique engagements (41 prior to recruitment and 60 during recruitment), totaling engagement with 180 partners across all events, including individual and group meetings, attendance at community events, and educational presentations. In addition to a primary partner community organization, the study team collaborated with a Community Advisory Council, comprised of residents, and civic and community leaders, and with the local health department and varied other organizations.

In CLIP, a high number of academic-community engagement encounters and close collaboration with community partners contributed to successful recruitment of Black men at risk for hypertension and with adverse social determinants. Our experience may serve as to inform investigators focused on recruiting underserved populations in hypertension research trials.
