The purpose of the present study was to test the effects of a culturally sensitive, health empowerment-focused, community-based health promotion program tailored to adult patients with type 2 diabetes on these patients' body mass index (BMI), blood pressure, and self-reported blood glucose levels, treatment adherence, and stress levels. Study participants (N = 130) consisted mostly of African Americans (70%) and Hispanic/Latinos (22.3%) who were divided almost evenly between an intervention group and wait-list control group. The tested health promotion program is informed by Health Self-Empowerment Theory. At post-test, program participants in the intervention group as compared to those in the control group demonstrated significantly lower levels of BMI, diastolic blood pressure, and physical stress. Implications of these study findings for future similar programs and research are discussed.
