Detailed Description:

To design and test the effectiveness of a lifestyle diabetes risk reduction program, Live Well, Be Well, to increase physical activity, decrease weight, and improve diet, offered in community-based settings to primarily lower income, minority persons aged 25 and older at moderate to high risk of diabetes. The design is a randomized controlled trial with the primary outcome being fasting plasma glucose; secondary outcomes are weight, physical activity, blood pressure, and other physiological risk factors as well as health-related quality of life. This project is a partnership between the University of California San Francisco and the City of Berkeley Division of Public Health.
