- BACKGROUND
The prevalence of obesity is increasing in Korea, including rural areas. We examined the changes in the prevalence of metabolic syndrome (MetS), defined by revised National Cholesterol Education Program (NCEP) or International Diabetes Federation (IDF) criteria, in a rural area of Korea during the past 6 years. METHODS: A total of 1,119 subjects (424 men and 695 women) aged > or = 30 years were initially recruited in 1997. Baseline clinical data and various laboratory values were obtained. Six years later, we performed a follow-up study in 814 subjects (316 men and 498 women) of which 558 were original participants and 256 subjects were new. The prevalence of MetS was assessed by the criteria of NCEP or IDF. RESULTS: The prevalence of central obesity and impaired fasting glucose increased in both sexes during the period between 1997 and 2003. The prevalence of MetS according to the IDF criteria also increased. In men, the age-adjusted prevalence of MetS was 10.9% in 1997 and 23.3% in 2003. In women, it was 42.2% in 1997 and 43.4% in 2003. However, the prevalence of MetS according to the NCEP criteria increased only in men. CONCLUSION: There have been increases in the prevalence of central obesity and MetS according to the IDF criteria during the recent 6 years in a rural area of Korea.

- BACKGROUND
Insulin resistance syndrome (IRS), a clustering of hypertension, impaired glucose tolerance, low HDL cholesterol and high triglyceride, is prevalent in Korea. We studied the correlational structure of IRS using factor analysis to evaluate whether a single process underlies in the clustering of these risk factors. METHODS: Factor analysis was performed using data from 1,018 non-diabetic subjects (388 men and 630 women) who participated in the Jungup epidemiological study. RESULTS: Factor analysis reduced 9 correlated risk factors to 4 independent factors, each reflecting a different aspect of IRS: hypertension factor (increased systolic and diastolic blood pressure), glucose intolerance factor (increased fasting and postload glucose), obesity factor (increased body mass index, waist circumference, and increased insulin), and dyslipidemia factor (increased trigly- cerides and decreased HDL cholesterol). Increased insulin was also loaded into dyslipidemia factor in men and glucose intolerance factor in women. These factors explained about 70% of the total variance in the data. Three factors such as the glucose intolerance factor, the dyslipidemia factor and the obesity factor, were linked through mutual association with hyperinsulinemia, while hypertension factor was not associated with hyperin- sulinemia. Age-adjusted mean BP by BMI tertile and fasting insulin level tertile for men and women increased progressively with increase in BMI in men and women. There was no significant elevation of mean BP according to increase in fasting insulin level. In contrast to premenopausal women in whom hyperinsulinemia show mutual association with the glucose intolerance factor, the dyslipidemia factor, and the obesity factor, hyperinsulinemia was only loaded into obesity factor in postmenopausal women. CONCLUSION: These results suggested that more than one process underlies the clustering of IRS. In sulin resistance alone did not seem to be the single underlying mechanism of IRS. Especially, hypertension was not correlated with hyperin- sulinemia.

- BACKGROUND
It has been suggested that adipose tissue releases leptin, a satiety factor, which circulates in blood and acts on the hypothalamus to suppress appetite. However, serum leptin concentration in obese human subjects is higher than that in lean subjects, suggesting leptin resistance. Although there have been several studies investigating serum leptin concentrations in Korean subjects, there has been no population-based study. This study was undertaken to investigate serum leptin concentration and associated factors in diabetic and non-diabetic subjects living in a rural area of Korea. METHOD: Among 898 subjects originally included in the Jung-up epidemiologic study, 119 men and 124 women with varying degrees of glucose tolerance were randomly selected. Serum leptin concentration was measured by radioimmunoassay. RESULTS: In agreement with previous studies, women had significantly higher serum leptin concentration than men. Serum leptin concentration in Korean men and women was apparently lower than in other populations, even after adjustment for BMI. Leptin concentration was not different among the three groups of glucose tolerance (normal glucose tolerance, impaired glucose tolerance and diabetes). Serum leptin concentration was positively correlated with serum true insulin, proinsulin and BMI in non-diabetic subjects. Serum leptin concentration was also significantly related with serum proinsulin/true insulin ratio in non-diabetic women. CONCLUSION: Serum leptin concentration in Korean subjects was lower than that reported in other populations. Serum leptin concentration was associated with BMI, serum true insulin and proinsulin levels in non-diabetic subjects, but not in diabetic ubjects.

- BACKGROUND
Microalbuminuria is associated with increased cardiovascular mortality in type 2 diabetic patients and non-diabetic subjects. This study was undertaken to determine the prevalence ot microalbuminuria among diabetic and non-diabetic subjects in Korea and to determine the factors associated with microalbuminuria. METHOD: A sample of 1,791 subjects aged > 40 years living in Jungup district were selected from the 28,380 inhabitants using a random cluster sampling method. Among these subjects, 1,006 of them (56.1%) underwent the 75 g oral glucose tolerance test that was also part of the timed overnight urine collection. 46 subjects were excluded because they had signs of urinary tract infection (n=41) or overt proteinuria (n=5). Microalbuminuria was defined as urinary albumin excretion rate (UAER) between 20 and 200 pg/min. RESULTS: Subjects with microalbuminuria had a higher weight and body mass index (BMI), abdominal circumference, systolic and diastolic blood pressure (BP), fasting and 2hr plasma glucose, fasting semm insulin and proinsulin concentrations than subjects without microalbuminuria. The prevalence of micro- albuminuria increased as the glucose tolerance worsened[6.0% in normal glucose tolerance, 11.8% in impaired glucose tolerance (IGT) and 21.8% in diabetes, respectively; x trend=25.9, p<0.(0001]. Mean UAER of subjects with hypertension was greater than that of subjects without hypertension (7.8+0.9ug/min vs. 9.6+0.7ug/min, p<0.001). Univariate analysis revealed that the UAER was significantly (p<0.05) correlated with weight and BMI, abdominal circumference, systolic and diastolic BP, fasting and 2hr plasma glucose, fasting serum insulin and proinsulin after sex-adjustment. Multiple regression analysis revealed that weight or BMI, diastolic BP, 2hr plasma glucose and fasting serum insulin were independently associated with UAER in non-diabetic subjects. CONCLUSION: The present study demonstrates that the prevalence of microalburninuria is higher in patients with glucose intolerance. The association of the UAER with BMI, diastolic BP, 2hr plasma glucose and fasting serum insulin suggest that microalbuminuria is a feature of the insulin resistance syndrome.

- 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.
