[Correlation of lipid profiles and anthropometric variables with serum lipoprotein(a) levels in childhood].
The aim of the present study was to evaluate lipoprotein(a) distribution in children and to assess its association with lipid profile and anthropometric variables. We studied 98 children (44 girls and 54 boys) with ages ranging from 6 to 7 years, who were included in an epidemiological study on the prevalence of hypercholesterolemia in children in the province of Biscay. The following parameters were determined: weight and height, body mass index, lipoprotein(a), and lipid profile. Lipid profile included total cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglycerides, apolipoprotein B, and apolipoprotein A1. The mean and median serum lipoprotein(a) levels were 13.07 and 5.56 mg/dl respectively and were 11.43 and 3.92 mg/dl for boys and 15.09 and 8.32 mg/dl for girls. Lipoprotein(a) concentrations > 30 mg/dl were found in 7.4% of the boys and in 11.4% of the girls. The mean values and prevalences of lipoprotein(a) > 30 mg/dl were lower in boys than in girls but these differences were not statistically significant. A positive correlation was found between lipid profile (LDL-cholesterol, apolipoprotein B and LDL-cholesterol/HDL-cholesterol index) and lipoprotein(a) levels. When evaluating anthropometric variables, we found a statistically significant inverse correlation between weight and lipoprotein(a). In view of the cumulative effect of cardiovascular risk factors and the results of this study, we believe that lipoprotein(a) determination should be considered in children with an unfavorable lipid profile.
