BACKGROUND
The clustering of hypertension, impaired glucose tolerance, low HDL cholesteml and high triglyceride is known as insulin resistance syndrome (IRS). We studied the prevalence of insulin resistance syndrome among subjects living in Jungup district, Korea. METHODS: Among a total of 151,000 subjects over 40 years of years living in Jungup district, a sample of 1,791 was selected using a random cluster sampling method. Oral glucose tolerance test revealed 1,018 subjects with normal or impaired glucose tolerance. The IRS was defined as the coexistence of two or more components of triad; hypertension, impaired glucose tolerance and dyslipidemia (triglycerides >= 200mg/dL and HDL <45 mg/dL for woman, HDL < 35 mg/dL for men). RESULTS: Twenty-one percent of men and 45% of women were obese and 50.8% and 61.9% were hypertensive. Eleven percent of men and 16 percent of women were found to have dyslipidemia. The prevalence of impaired glucose tolerance was 10.2% for men and 15.7% for women. The prevalence of IRS in the Jungup population was 12.8% for men and 19.6% for women. The prevalence of IRS increased according to the plasma level of insulin. There was a positive correlation between the number of components of IRS and the level of fasting plasma insulin. CONCLUSION: We conclude that the prevalence of IRS is high in Korean subjects. The close correlation between the IRS components and fasting insulin level suggests that cardiovascular risk is associated with insulin resistance.

BACKGROUND
Similar to other countries that underwent industrialization in recent years, the prevalence of diabetes has increased dramatically in Far East Asian countries. While the prevalence of diabetes in South Korean adults was estimated to be less than 0.5% in 1960s, a recent study from Yonchon County showed a dramatic increase to 7.2%. This was the only study performed in population-based subjects. We studied the prevalence of diabetes and impaired glucose tolerance(IGT) among subjects living in Jungup clistrict, Chonlabuk-do, South Korea. METHODS: Among a total of 28,380 subjects aged over 40 years living in Jungup district a sample of 1,791 subjects living in six villages was selected using a random cluster sampling method. Among these subjects, 1,108 subjects(61.9%) completed 75g oral glucose tolerance test(OGTT). RESULTS: When the WHO criteria were used, the prevalence of diabetes and IGT were 7.1% and 8.5%, respectively, after correction for Segi's standard world population. Among the diabetic subjects, 62% of the patients did not know that they had diabetes previously. When the 1997 ADA criteria after OGTT were employed, the prevalence of diabetes and IGT/IFG(impaired fasting glucose) was 8.5% and 11.1%, respectively. The mean body mass index(BMI) of whole subjects was 22.9+2.7 for men and 24.3+3.2kg/m for women. Among subjects with normal glucose tolerance, IGT and diabetes, 31.5%, 42.3% and 50.0% of subjects were currently obese(BMI >25kg/m), respectively. The prevalence of both diabetes and IGT increased with inereasing waist-to-hip ratio(WHR) in men and women. On the other hand, the prevalence of diabetes and glucose intolerance increased with increasing BMI only in women but not in men. CONCLUSION: The prevalence of diabetes and IGT in the present study was quite similar to that in the previous Yonchon study. This prevalence of diabetes is higher than or similar to that reported in the Caucasian(~ 3% 8%), even though mean BMI of this community population(23.9 kg/m) is lower than that in the Caucasian (24.5~28.0 kg/m). It can be speculated that Far East Asian penple are more prone to develop diabetes for their degree of obesity.
