Lessons learned in recruiting and retaining Black men in behavioral diabetes intervention research

Black men experience disproportionately high rates of type 2 diabetes (T2D) and its complications, yet remain underrepresented in diabetes intervention research. Culturally tailored, community-based interventions that prioritize trust and address structural barriers are essential for improving recruitment and retention in this population. This article provides insights from the Michigan Men's Diabetes (MenD I and II) Projects, a peer-led diabetes self-management intervention tailored to Black men with T2D. MenD I and MenD II used Diabetes Self-Management Education (DSME) and Peer-Led Diabetes Self-Management Support (PLDSMS) sessions delivered virtually to meet participants' needs. Recruitment efforts engaged trusted community organizations, healthcare providers, and targeted outreach. Retention strategies emphasized trust-building, flexible scheduling, and culturally resonant support mechanisms, such as fostering a sense of community, providing personalized check-ins, and incorporating time for informal interactions and relationship-building. Data collected from pre- and post-intervention assessments and participant feedback illustrate the effectiveness of these approaches in addressing barriers and sustaining engagement. Despite challenges like medical mistrust, systemic inequities, and competing responsibilities, the MenD studies demonstrate that well-designed peer-led interventions can effectively engage Black men. These findings highlight the importance of culturally tailored adaptations and strong community partnerships in overcoming barriers to participation. Insights from MenD I and II offer valuable guidance for reducing health disparities and improving diabetes outcomes for Black men.
