Abstract
Objective: To evaluate the efficacy of the group program PREDIAS for diabetes prevention.
Research design and methods: PREDIAS consists of 12 lessons and aims at lifestyle modification. The control group received written information about diabetes prevention. In this study, a total of 182 persons with an elevated diabetes risk participated (aged 56.3 +/- 10.1 years, 43% female, and BMI 31.5 +/- 5.3 kg/m(2)).
Results: After 12 months, weight loss was significantly higher (P = 0.001) in PREDIAS than in the control group (-3.8 +/- 5.2 vs. -1.4 +/- 4.09 kg). There were also significant effects (P = 0.001) on fasting glucose (control group 1.8 +/- 13.1 mg/dl vs. PREDIAS -4.3 +/- 11.3 mg/dl), duration of physical activity per week (control group 17.9 +/- 63.8 min vs. PREDIAS 46.6 +/- 95.5 min; P = 0.03), and eating behavior.
Conclusions: PREDIAS significantly modified lifestyle factors associated with an elevated diabetes risk.
Trial registration: ClinicalTrials.gov NCT00707447.
