The aims of this study were to determine recruitment and retention feasibility, changes in self-efficacy for diet and exercise, and weight and fasting insulin level change after a lifestyle intervention in a community park. A randomized wait-list control design was used to recruit 50 Filipino American participants into a flexible eight-week curriculum. The retention rate was 88%. A weight loss of 1.52 kg (p < .05) and a waist reduction of 5.46 cm (p < .05) were found in the intervention group. Significant predictors for weight loss were gender and marital status. The intervention showed promise for this community program.
