Screening for serum total cholesterol (Ch), triglyceride (Tg) and HDL-Ch levels was performed in 3 Hungarian rural areas among 3-14-year-old children, divided into three groups: 3-6, 6-10 and 10-14-year-old, respectively. The mean levels as well as the 85, 90 and 95 percentile values of the investigated lipids are given. The serum HDL-Ch levels were very low in all three groups: 0.96 mmol/l in group I. (3-6 years), 0.99 mmol/l in group II. (6-10 years) and 1.04 mmol/l in the group III. (10-14 years). We did not found any correlation between the age and lipid parameters of the children. Significant positive correlation was detected between the serum Ch and HDL-Ch levels, and a significant negative correlation was observed between the serum Tg and HDL-Ch concentrations. Our data represent the normal lipid values (Ch, Tg, HDL-cholesterol) for 3-14-year-old children, living in rural area.
