Detailed Description:

Diabetes is common and rapidly increasing, because of obesity, unhealthy eating habits, and physical inactivity in Korea. Many studies reported that lifestyle modification related in the primary prevention of diabetes in multiethnic populations. The aim of this study is to determine whether internet-based interventions in those at high risk may delay the development of T2DM, and thereby reduce the incidence of cardiovascular diseases and strokes in Korean populations. In January 2008, participant recruitment began in Chung-ju city, a rural area in Korea. The subjects with IGT or elevated fasting plasma glucose concentrations were selected from initial screening and then randomized to either a control or intensive lifestyle group to carry out intervention over 4 years. The primary outcome of this study is the development of diabetes by ADA criteria. To confirm the onset of diabetes, all subjects have an OGTT at the interim 6-month and each annual visit. Also, systematic evaluation examination will be done at the same time. The proportion of subjects developing diabetes in each group and the factors relating the progression will be estimated using statistical analysis.
