A culturally adapted, social support-based, diabetes group visit model for Bangladeshi adults in the USA: a feasibility study

BACKGROUND: Interventions focused on weight loss can prevent, delay, and improve management of type 2 diabetes (T2D). However, implementation of these programs is challenging in diverse populations. South Asians have higher risk for T2D, yet to date, there have been limited programs for this community in the USA. The aim of this project was to develop and test the feasibility of a tailored group visit model for Bangladeshis with type 2 diabetes (T2D) or prediabetes based in primary care. DESIGN: Mixed-methods single-arm feasibility study. SETTING: An academic health center-based primary care clinic in Atlanta, Georgia. PARTICIPANTS: Bangladeshi adults > 18 years old with T2D or prediabetes METHODS: In conjunction with a community-academic board, we conducted focus groups to tailor an existing evidence-based curriculum to a culturally acceptable intervention. Fourteen participants enrolled in the 16-week program focusing on healthy diet, exercise, and weight loss. The primary feasibility outcomes were number of sessions attended and participant satisfaction with the intervention. Weight, blood pressure, cholesterol, and HbA1C were measured at beginning and end of study. Participants were asked to evaluate each session on level of satisfaction. One tailed paired t tests were used to test significance of pre-post changes in outcomes. RESULTS: Key themes from the formative focus groups (n = 50) were closely tied to sociocultural beliefs and included: dietary patterns, physical activity perceptions, and healthcare access concerns. In the intervention, 10 of 14 participants had baseline and follow-up data. Participant attendance averaged 50%. Statistically significant reductions in mean weight (− 2%, 95%CI: − 3.1, 0.2 kg), systolic/diastolic blood pressure (− 12.7 mmHg [95%CI: − 23.2, − 2.2]/− 3.7 mmHg [95%CI: − 7.6, − 0.1], respectively), and triglycerides (− 62.6 mg/dl, 95%CI: − 123.1, − 2.0) were noted. Overall, participants reported high levels of satisfaction with the program. CONCLUSION: A lifestyle program based in primary care is feasible and acceptable for Bangladeshi immigrants. Larger studies testing the effectiveness of group programs, in primary care, to improve cardiometabolic factors are important. TRIALS REGISTRATION: ClinicalTrials.gov; NCT03861546.
