• Interventions: Behavioral: Intensive Lifestyle Intervention

• Registration Number: NCT00848757
• Lead Sponsor: Yale University

Brief Summary

The purpose of this research collaboration between Dr. William Tamborlane, Deputy Directory of the Yale Center for Clinical Investigation (YCCI) and Fair Haven Community Health Center's (FHCHC) Diabetes Prevention Team is to determine the efficacy of an intensive life-style intervention (ILI) program that has been developed and implemented at the FHCHC to prevent the development of diabetes.

Detailed Description

This project is a clinical outcome study that merges the expertise of a senior Yale clinical investigator, the clinical and translational research resources of YCCI, the clinical and community expertise of the FHCHC Diabetes Team, and the high-need patient population of FHCHC. In addition to determining the efficacy and cost-effectiveness of an ILI for diabetes prevention in an inner-city community health center setting, this project will evaluate the effectiveness of pooling academic expertise with direct clinical services to disadvantaged, at-risk populations.
