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/m²). 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.
