Hyperlipidemia is an important public health concern because it is frequently associated with conronary heart diseases(CHD). Many researchers have attempted to measure the prevalence and extent of the relationship of hyperlipidemias with CHD.

However, this relationships are based on the statistical data of western populations. We expected that the Korean population nas a different pattern of serum lipid and lipopretein distribution. In this study we hope to provid information on the distribution of serum lipid selected healthy Korean adults and try to find out the factors affecting serum lipidand lipoproteins before we have our nation-wide epidemiologic study for serum lipid distributions in near future.

Total 3101 subjects were entrolled to this collaborative lipid study from 17 ddifferent hospitals, which were located in 7 ddifferent cities; Seoul, Pusan, Taegu, Kwangji, Taejun, Wonju and Choonchon.

The sampling population for this study was composed of those who were scheduled to have annual physical checkup. Most of them were government employee, mannual and clerical workers of industry, and school teachers.

The level of total cholesterol was 185±40mg/dl, HDL cholesterol; 45±13mg/dl, LDL cholesterol; 115±37mg/dl and triglyceride; 127±67mg/dl.

The BMI(body mass index) and age were statistically significant factors in total cholesterol and LDL cholesterol. Also the BMI and smoking were statistically affecting factors in HDL cholesterol and triglyceride.
