Diabetes Prevention Program (DPP) translation for diabetes risk reduction in Chinese immigrants in New York City
Objective: We received a NIH R34 funding to evaluate the acceptability and feasibility of implementing a modified and culturally-appropriate DPP program in pre-diabetic Chinese immigrants living in New York City. Presented here are preliminary findings of the study.
Methods: Sixty participants were randomized into either lifestyle intervention (n=30) where they received 12 bi-weekly group sessions or control group (n=30) where they received health information via mail quarterly. Each intervention session lasted about 1 to 1.5 hours and covered topics such as healthy eating, physical activity, stress reduction and problem solving skills. Additionally, intervention participants also received six monthly post-core sessions including supermarket tours, ping-pong, karaoke and walking to city parks. Outcomes such as change in weight, BMI, hemoglobin A1c were assessed at baseline, 6 and 12 months. A mixed-effects linear regression was applied to test the intervention effect at months 6 and 12. Significance level was set at p < 0.05.
Results: Participant attrition rate was less than 5% (2 out of 60) at 12 months. The intervention had a significant overall effect on percent weight loss (-3.5% vs.-0.1%, p=.0001) at month 6, which was largely maintained at month 12. Changes in hemoglobin A1c at month 12 were also significant (0.1% vs. 3.8%, p<.05).
Discussion/Conclusions: the pilot study strongly indicated to the superiority of the intervention. Testing of the translated DPP curriculum in a larger trial is warranted.
