Abstract 862: A Latino Community Intervention for the Prevention of Diabetes: The Lawrence Latino Diabetes Prevention Project
Background Diabetes is an important risk factor for CHD, and Latinos have a high prevalence of diabetes. The Diabetes Prevention Program (DPP) demonstrated that an intensive lifestyle intervention reduced the incidence of diabetes by 58% versus usual care. We designed a less-intensive group-based program utilizing a community-based approach to lifestyle change in a low socioeconomic status, low education Latino population.
Methods Three hundred and twelve Latino participants from Lawrence, Massachusetts were randomized into lifestyle intervention (IC) and usual care (UC) conditions. Participants had a ≥30% probability of developing diabetes in the next 7.5 years as judged by a predictive algorithm. The IC utilized 3 individual home visits and 13 group visits, and was implemented by Spanish-speaking individuals from the community with training and supervision by a registered dietitian and a behavioral psychologist. Each participant was followed for one year.
Results The average age of participants was 52 years, 58.6% had less than a high school education, 44% were married, and 43% were employed. The one-year study retention rate was 93%. Reductions in glycosylated hemoglobin (HbA1c) (−0.10 versus −0.04%), and weight (−2.6 versus −0.86 lbs) were significantly greater in the IC condition as compared to the UC condition, p=0.009 and 0.004 respectively. Greater reductions in percent calories from total and saturated fat were also observed in the IC compared to UC condition (−1.89 versus 0.05, −0.79 versus −0.04, respectively). Overall session attendance rate significantly predicted weight loss. Median weight loss with 7 sessions or less was 0.125lbs but with >7 sessions was 4.75lbs (p<0.0001).
Conclusions The DPP can be successfully translated into a community-based intervention in a low-income Latino population, albeit with a lesser degree of weight loss but a similar one-year HbA1c change.
