Background: Asians comprise a rapidly increasing group of first generation immigrants in the United States, and Chinese immigrants comprise the fastest growing subgroup of Asian immigrants. Our prior studies indicated a high prevalence of impaired fasting glucose for Chinese immigrants. Adaptation of the Diabetes Prevention Program (DPP) lifestyle intervention to create an implementation model for urban Chinese immigrants is urgently needed.

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.
