MedicalResearch.com: What is the background for this study?
Dr. Kriska: The Diabetes Prevention Program (DPP) was a well administered national research study primarily supported by the National Institutes of Health (NIDDK) that demonstrated that lifestyle intervention with weight loss and physical activity goals can prevent type 2 diabetes in diverse, high risk US adults. The importance of physical activity in preventing diabetes development in the DPP until now was thought to be due to its role in achieving weight loss and weight maintenance but activity was not considered a strong key factor alone.
The lifestyle group had a significantly greater increase in physical activity and decrease in weight than the other two groups. They also had a 58% decrease in diabetes incidence compared to the control group. The successful decrease in T2D held across all age, sex, baseline BMI and ethnicity/race subgroups.
Despite the fact that the lifestyle intervention was then offered to all participants, in the follow-up years, the lifestyle participants still maintained a lower cumulative diabetes incidence that could not be explained by differences in weight loss.
