Evaluation of a Community-based Translation of the National Diabetes Prevention Program for Latinos

In an effort to address rising rates of diabetes among Latinos, we implemented a community-based translation of the National Diabetes Prevention Program (NDPP) conducted in partnership between the University of Colorado and community organization CREA Results. We followed the CDC-championed NDPP curriculum and yearlong format of 16 weekly/biweekly group sessions followed by 6 monthly group sessions. Sessions were led by trained CREA Results promotoras and conducted in English or Spanish based on participant preference. We recruited in community settings, including churches, schools, and community health fairs. Eligibility was based on 2015 Diabetes Prevention Recognition Program (DPRP) guidelines (≥18 yo, BMI ≥24, and diabetes risk based on abnormal glucose, history of gestational diabetes, or CDC diabetes risk test). Evaluation metrics were based on DPRP guidelines, including 6-month goals of ≥9 sessions attended and 5% average weight loss. Of 521 individuals who attended ≥1 sessions over the 1-year evaluation period, 81% (n=424; 45 ± 12 yo, 85%F/15%M, 98% Latino) met DPRP eligibility criteria. Most attended sessions in Spanish (90%), and there were no differences in attendance or weight change based on language.  Among the 98% who attended ≥4sessions, average attendance during first 6 months was 13 sessions and mean weight loss was 3%. Attendance goal of ≥9 sessions was achieved by 80%, and goal of 5% weight loss was achieved by 27% of participants. While we demonstrated high attendance rates, additional work is needed to identify barriers to weight loss among Latinos participating in lifestyle intervention programs like the NDPP.
