This study evaluated the effectiveness of participation in the National Diabetes Prevention Program (NDPP) for weight reduction in a sample of prediabetic individuals in an urban medically underserved community. The NDPP was developed from research demonstrating a reduced risk for diabetes in prediabetic individuals who participated in an intensive lifestyle intervention program aimed at reducing weight and improving lifestyle habits. The NDPP was integrated into existing services within a medically underserved urban community health center to provide this evidence-based program targeted to high-risk prediabetic patients. The participants received weekly group sessions aligning with the 2012 NDPP curriculum. Study data was obtained through the 16-session core program of the NDPP. Pre-test, post-test paired group t-tests were completed to evaluate the change in mean weight and body mass index (BMI) at the beginning and end of the core program. Correlational analyses were completed to evaluate the association between weight change, age, gender, number of sessions attended, and total minutes of physical activity. Twelve participants initiated the program, and eight completed at least four of the 16 sessions. The mean weight loss for all participants was 5.3 pounds, and 7.4 pounds for those who completed at least four sessions. There was a significant difference in pre-weight, post-weight and BMI (p < 0.05) for all participants and those who completed a minimum of four sessions. Weight loss was independent of age and gender. A significant positive correlation was found between weight loss and both number of sessions attended (p < 0.05) and total minutes of physical activity (p < 0.05). Participation in the core portion of the NDPP significantly reduced weight and BMI in a group of prediabetic individuals in an urban medically underserved community, with weight loss unrelated to age and gender. A greater level of weight loss was associated with higher levels of program participation through session attendance and physical activity. There was an observable discrepancy between the final program weight and the lowest weight attained, suggesting the importance of considering weight fluctuations in evaluating program effectiveness in communities where medical and psychosocial impacts on weight loss are likely to occur.
