<p><b>OBJECTIVE</b>To investigate the serum levels of cholesterol, triglyceride and high density lipoprotein cholesterol in children aged 3-14 years and its influencing factors.</p><p><b>METHODS</b>The cross-sectional survey study population was a representative sample from Guangdong province obtained by multi-stage randomized cluster sampling. Serum lipids in 6188 children aged > or = 3 years were assayed using automatic biochemical instrument. The data of social and demographic status were collected by face-to-face interview, and height and weight were obtained by physical examination.</p><p><b>RESULTS</b>The age-standardized and region-weighted means of serum total cholesterol (TC), triglyceride (TG), and high density lipoprotein cholesterol (HDL-C) were 0.80 mmol/L, 3.50 mmol/L and 1.28 mmol/L, respectively. For the mean of TG, there was no difference between metropolitan and middle city, nor between rich county and poor county. For TC, it was the highest in metropolitan, and there was no difference between rich and poor county. For HDL-C, the difference existed between every two regions. The age-standardized and region-weighted prevalence of high TG, high TC and low HDL-C were 2.2%, 2.1% and 8.0%, respectively. Metropolitan, rich county, low weight and age between 7.0-9.9 years are protecting factors for high TG, and the number of family between 3-4, age between 7.0-9.9, metropolitan, middle city and poor county are risk factors for high TC. Male, family income per year between 800-9999 RMB, middle city, rich county are protecting factors for low HDL-C.</p><p><b>CONCLUSION</b>The prevalence of abnormal serum lipid was still low compared with other regions in China. The region, number of family member, age and sex may be the important factors influencing on serum lipid levels.</p>
