[The Fuenlabrada study: lipids and lipoproteins in children and adolescents]

Abstract

Lipids and lipoproteins were studied in 2,153 healthy children, of both sexes, aged 0 to 18 years old, of Fuenlabrada, Madrid, population. We determined: Total Cholesterol (TC) and Triglycerides (TG) by automatized enzymatic techniques. C-HDL by precipitation method. C-LDL and C-VLDL were calculated by Friedewald-Fredrickson equation. Our laboratory have previously standardized the techniques of obtention of TC, TG and C-HDL using serums of reference. Mean values were: TC = 166 +/- 36 mg/dl, TG = 63 +/- 39 mg/dl, C-HDL = 53 +/- 13 mg/dl, C-LDL = 102 +/- 34 mg/dl, C-VLDL = 13 +/- 6 mg/dl. In our population 14% had TC greater than or equal to 200 mg/dl, 2.6% TG greater than or equal to 140 mg/dl and 15% C-HDL less than or equal to 40 mg/dl. During adolescence a significant change in the lipid and lipoprotein pattern in both sexes was observed. At the end of the adolescence, males had C-HDL lower and TG, C-LDL and C-VLDL higher than females. Correlations and associations of lipids and lipoproteins were similar in our population than in adult population. The mean finding of this study is the actual high level of TC in our children population.
