This is a cross-sectional study to evaluate the serum lipid levels of children living in Pusan in 1996. The distribution of age is from 2 years old to 12 years old. In female children mean total cholesterol is 171.4+/-26.2mg/dl, triglyceride is 104.7+/-50.6mg/dl, HDL-cholesterol is 54.4+/-14.8mg/dl, and LDL-cholesterol is 95.4+/-32.9mg/dl. In male children mean total cholesterol is 167.9+/-25.2mg/dl, triglyceride is 90.6+/-45.5mg/dl, HDL-cholesterol is 55.4+/-11.7mg/dll, and LDL-cholesterol is 94.4+/-23.6mg/dl. The percentile of serum lipid levels is measured in children. The 95th percentile of serum total cholesterol is 210mg/dl in male children, and 214mg/dl in female children. And, the 95th percentile of serum triglyceride is 184mg/dl in male children, and 191mg/dl in female children. And, the 95th percentile of LDL-cholesterol is 133mg/dl in male children, and 135mg/dl in female children. Serum total cholesterol is positively related to age(r=0.18), height(r=0.08), weight(r=0.17), obesity index(r=0.12), and negatively related to father's education level(r=-0.13), mother's education level(r=-0.13). Serum triglyceride is positively related to weight(r=0.23), age(r=0.31) and negatively related to father's education level(r=-0.12), mother's education level(r=-0.18). Serum HDL-C was positively related to mother's education level(r=0.07) and negatively related to height(r=-0.12), weight(r=-0.09). Conclusively, the serum lipid levels of children living in Pusan is generally so high that the family and school must try to control the serum lipid levels.
