Diabetes Prevention Program Generates Promising Results.

Participants in a 24-month lifestyle weight-loss program experienced greater decreases in fasting glucose (−4.35 mg/dL); insulin (−3.01 μU/mL); insulin resistance (−0.97); body weight (−4.19 kg); waist circumference (−3.23 cm); and BMI (−1.40) than participants receiving enhanced usual care. The program, which was based on the Diabetes Prevention Project and was led by community health workers, sought to induce weight loss that would be maintained through decreased caloric intake and increased physical activity. Enhanced usual care involved two visits with a registered dietitian and a monthly newsletter. The findings are published in theAmerican Journal of Preventive Medicine.
