Arms Assigned Interventions
Experimental: 1
Individually administered weight loss intervention, based on the Diabetes Prevention Program, delivered by telephone in primary care practices.
 Behavioral: Individual telephone intervention
Individually administered telephone-based weight loss intervention based on the Diabetes Prevention Program (weekly nurse calls for the first 5 weeks, then monthly, to cover the 16 topics from the Diabetes Prevention Program). In year 1 (after the first 5 weeks), the "coach" will have 3 weekly calls per month with participants. Contact will decrease to monthly in year 2. In year 3 there will be no contact arranged by study staff.
Active Comparator: 2
Group education conference calls to deliver the weight loss intervention, based upon the Diabetes Prevention Program, in primary care practices.
 Behavioral: Group telephone intervention
Group education conference calls administered weight loss intervention based on the Diabetes Prevention Program (weekly nurse calls for the first 5 weeks, then monthly, to cover the 16 topics from the Diabetes Prevention Program). In year 1 (after the first 5 weeks), the "coach" will have 3 weekly calls per month with participants. Contact will decrease to monthly in year 2. In year 3 there will be no contact arranged by study staff.

Detailed Description:

Obesity is related to the rising incidence of type 2 diabetes. Cost-effective interventions leading to sustained weight loss are needed to improve the public health and reverse the alarming rise in diabetes, its cardiovascular complications and other obesity-related illnesses. The Diabetes Prevention Program is identified as a model for a successful weight loss intervention. The proposed study is a randomized controlled trial of 2 active telephone-based interventions based on the Diabetes Prevention Model that will be delivered at primary care sites.
