[A study from Navarra. Hyperlipidemias. Avarage scores and percentiles for lipids and lipoproteins in a population of children and adolescents. Correlation with anthropometric parameters].

As part of an epidemiological study on cardiovascular risk factors among children and adolescents in Navarra, the following parameters: total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides and C/HDL and LDL/HDL risk quotients were determined in 5,829 children. These children, of both sexes and between the ages of 4 and 17 years, were selected at random from the school population in our community. Average values and percentiles of these parameters were obtained for each group according to age and sex as a previous step to define the health condition or "lipid risk" in our population. When determining the correlation of these biochemical parameters with the anthropometrical parameters of BP, age, weight, height, Quetelet Index, body mass surface, skinfold thickness and the percentage of subcutaneous fat (after the necessary logarithmic transformations, adjusted to each age and sex group by Z-scores) we find that none of the correlation coefficients are significant. The triglycerides and the HDL-cholesterol have a low, but significant. The triglycerides and the HDL-cholesterol have a low, but significantly, correlation with the other lipid parameters. The lipid risk quotient (C/HDL, LDL/HDL) shows a higher correlation with LDL-cholesterol than with total cholesterol.
