Diabetes, Cardiovascular Risks, and Lipoproteins

Objectives. We tested the effectiveness of a community-based, literacy-sensitive, and culturally tailored lifestyle intervention on weight loss and diabetes risk reduction among low-income, Spanish-speaking Latinos at increased diabetes risk. Methods. Three hundred twelve participants from Lawrence, Massachusetts, were randomly assigned to lifestyle intervention care (IC) or usual care (UC) between 2004 and 2007. The intervention was implemented by trained Spanish-speaking individuals from the community. Each participant was followed for 1 year. Results. The participants’ mean age was 52 years; 59% had less than a high school education. The 1-year retention rate was 94%. Compared with the UC group, the IC group had a modest but significant weight reduction (−2.5 vs 0.63 lb; P = .04) and a clinically meaningful reduction in hemoglobin A1c (−0.10% vs −0.04%; P = .009). Likewise, insulin resistance improved significantly in the IC compared with the UC group. The IC group also had greater reductions in percentage of calories from total and saturated fat. Conclusions. We developed an inexpensive, culturally sensitive diabetes prevention program that resulted in weight loss, improved HbA1c, and improved insulin resistance in a high-risk Latino population.
