A Randomized Trial of Diabetes Prevention Through Lifestyle Change in India

People from the Indian subcontinent are more likely to get diabetes, even at younger ages. The Diabetes Community Lifestyle Improvement Program (D-CLIP) will test in a randomized trial if a culturally specific, community-based lifestyle and metformin (for individuals who do not respond to lifestyle change alone) intervention for men and women living in Chennai, India can effectively prevent type 2 diabetes in high-risk individuals. Lifestyle interventions are programs that seek to prevent disease by promoting changes in health behaviors, improved diet, increased physical activity, and weight loss. The results of this program will be used to make policy and public health recommendations, which will result in broader diabetes prevention efforts. The research team hypothesizes that this program will result in improvements in health (diabetes prevention, weight loss, and improvements in other markers of chronic disease) for intervention participants compared to participants in the control arm of the study.
