OBJECTIVE--To determine the prevalence of diabetes and impaired glucose
tolerance (IGT) in Yonchon County of South Korea and to investigate their
associated factors. RESEARCH DESIGN AND METHODS--We performed a
population-based cross-sectional study with random cluster sampling of
residents > or = 30 years of age. Among the 3,804 residents sampled, a
total of 2,520 participants had a standard 75-g oral glucose tolerance test
and answered a detailed questionnaire. We also collected standard
anthropometric data. RESULTS--If the data for participants in the age range
of 30-64 years were adjusted to the standard world population, the
prevalence of diabetes was 7.2% and the prevalence of IGT was 8.9%. It was
observed that the significant factors associated with diabetes were
waist-to-hip circumference ratio, serum triglyceride levels, age, systolic
blood pressure, family history of diabetes, and locality. CONCLUSIONS--The
prevalence of diabetes in Yonchon County was substantially higher than was
previously suggested. The risk of diabetes increased with the increased
central obesity and metabolic disturbances associated with insulin
resistance.
