Engaging People in Medically Underserved Areas in the Community-Based Healthy Eating and Active Living to Reverse Diabetes (HEAL Diabetes) Program

Background/Objectives: Recruiting and retaining low-income participants in community-based diabetes interventions remains a persistent challenge, particularly in medically underserved areas. This study describes engagement strategies and lessons learned recruiting for a 12-month pilot of a community-based, medically tailored nutrition program for diabetes remission and weight loss. Methods: A descriptive, exploratory mixed-methods study was performed to assess the effectiveness of recruitment and engagement strategies in the HEAL Diabetes program and identify areas for improvement. Recruitment and enrollment data were tracked utilizing recruitment logs and field notes. Descriptive statistics were used to analyze recruitment activity and retention rates, while qualitative analysis of fieldnotes identified key barriers and facilitators. Results: Among 83 eligible participants, 63 (75.9%) completed the in-person screening and 35 (55.6% enrollment rate) enrolled. Retention was high, with 30 completing the study. Participants were largely African American (97.1%), female (70.6%), average age of 59.8 years, with a household income below USD 49,000 (74.3%). Recruitment cycles achieved 87.5% of the target before budget constraints halted enrollment. Recruitment was hindered by limited clinical integration, social barriers and life demands, while facilitators to recruiting included trust, flexibility, and tangible support for participation. Conclusions: Conventional recruitment methods, including registry-based approaches, were insufficient for engaging underserved populations. Participant-centric strategies, emphasizing trust, practical support, and structural and cultural relevance, can help enhance enrollment and retention. Effective engagement in community-based diabetes interventions requires multifaceted approaches that address clinical, social, and structural barriers to participation.
