[BDSP. Notice produite par INIST e0xR0x6u. Diffusion soumise à autorisation]. Objectives : Plasma lipoprotein (a) [Lp (a) ] is a risk factor for cardiovascular disease. The purpose of this study is to evaluate the correlation of anthropometric measures, lipids and lipoprotein profiles and serum Lp (a) values among children in Taiwan. We will attempt to find parameters that will be able to predict Lp (a) levels in children. Design and methods : After a probability-proportional-to size, multi-stages sampling procedure, we randomly sampled 1500 schoolchildren from 10 schools in Taipei city. Anthropometric measures including body weight, body height, waist and hip circumference and skinfolds were measured. We used standard methods to measure serum total cholesterol (CHOL), triglycerides (TG), high density lipoprotein-cholesterol (HDL-C), apolipoprotein A1 and B (ApoAl and ApoB) and Lp (a) levels. We also calculated low density lipoprotein-cholesterol (LDL-C) and CHOL/HDL-C ratio (TCHR) by formula. Results : We sampled 1283 children (635 boys and 648 girls) with a mean age of 13.3 years (from 12 to 16 years) in this study. The mean and medium serum Lp (a) levels were 16.8 and 8.8 mg/dl among boys and 20.8 and 11.9 mg/dl among girls. Children in the highest quintile of Lp (a) (mean=49.6 and 58.6 mg/dl for boys and girls, respectively) had higher CHOL, LDL-C. ApoB levels and TCHR than children in the lowest quintile (mean=3.1 and 3.7 mg/dl for boys and girls, respectively). (...)
