The healthy living partnerships to prevent diabetes and the diabetes prevention program: a comparison of year 1 and 2 intervention results

Transl Behav Med. 2017 Jun;7(2):371-378. doi: 10.1007/s13142-016-0447-z.


A number of research studies have attempted to translate the behavioral lifestyle intervention delivered in the Diabetes Prevention Program (DPP). To compare the active interventions of two trials, Diabetes Prevention Program DPP and Healthy Living Partnerships to Prevent Diabetes (HELP PD), after 1 and 2 years of intervention. DPP included 3234 adults with prediabetes randomized to intensive lifestyle intervention, metformin, troglitazone, or placebo. The lifestyle intervention, professionally delivered to individuals in a clinical setting, focused on diet and increased physical activity. HELP PD, a community-based translation of DPP, included 301 adults randomized to receive intensive lifestyle intervention or enhanced usual care. Mean weight-losses at 1 year (6.9 kg in DPP, 6.4 kg in HELP PD) and 2 years (5.5 kg in DPP, 4.4 kg in HELP PD) were similar across studies. Reductions in glucose were also similar across studies at both time points (5.2 mg/dL in DPP and 4.1 mg/dL in HELP PD at 1 year; 1.8 mg/dL and 1.6 mg/dL at 2 years). HELP PD participants achieved larger reductions in triglycerides at 1 and 2 years (38.4 mg/dL and 34.9 mg/dL, respectively) than DPP participants (24.8 mg/dL and 22.4 mg/dL). High-density lipoprotein decreased in HELP PD participants at year 1 (-0.6 mg/dL) and increased in DPP (1.2 mg/dL) but there were no significant differences in year 2. HELP PD, a community model for diabetes prevention, was similar to DPP in reducing body weight and lowering blood glucose, both important risk factors that should be controlled to reduce risk for developing type 2 diabetes.
