Aims To evaluate the effectiveness and feasibility of implementing a linguistically and culturally tailored Diabetes Prevention Program among Chinese immigrants with prediabetes living in New York City. Methods A total of 60 Chinese immigrants with prediabetes were randomized into either a Diabetes Prevention Program lifestyle intervention (n=30) consisting of 12 bi-weekly core sessions and six monthly post-core sessions or the control intervention (n=30), consisting of quarterly mailing of diabetes prevention information. Each Diabetes Prevention Program intervention session lasted 1.5–2 h and covered topics such as healthy eating, physical activity, stress reduction and problem-solving skills. Outcomes such as percent change in weight, BMI, and HbA1c concentration 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. Data were collected in the period 2012–2013 and analysed in 2014. Results The participant attrition rate was < 5% (2 out of 60) at 12 months. There was a significantly greater percent weight loss in the intervention group (−3.5 vs. −0.1%; P=0.0001) at 6 months, which was largely maintained at 12 months (−3.3 vs. 0.3%; P=0.0003). Conclusions Participants in a Diabetes Prevention Program-based intervention achieved greater weight loss and improvements in HbA1c concentration than control participants. Evaluation of the Chinese Diabetes Prevention Program curriculum in a larger trial is warranted.

BackgroundBetter techniques are needed to help consumers make lower calorie food choices. This pilot study examined the effect of menu labeling with caloric information and exercise equivalents (EE) on food selection. Participants, 62 females, ages 18-34, recruited for this study, ordered a fast food meal with menus that contained the names of the food (Lunch 1 (L1), control meal). One week later (Lunch 2 (L2), experiment meal), participants ordered a meal from one of three menus with the same items as the previous week: no calorie information, calorie information only, or calorie information and EE.ResultsThere were no absolute differences between groups in calories ordered from L1 to L2. However, it is noteworthy that calorie only and calorie plus exercise equivalents ordered about 16% (206 kcal) and 14% (162 kcal) fewer calories from Lunch 1 to Lunch 2, respectively; whereas, the no information group ordered only 2% (25 kcal) fewer.ConclusionsMenu labeling alone may be insufficient to reduce calories; however, further research is needed in finding the most effective ways of presenting the menu labels for general public.
