[Levels of cholesterol, HDL-cholesterol, LDL cholesterol and triglycerides in blood serum of children from Silesia].

In order to estimate the mean and borderline total cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride levels, a group of 1151 children aged 7 to 15 years was examined. They were randomly chosen from elementary schools in Katowice, the capital city of Silesia. Significantly lower total cholesterol levels were found in 14-15 year old boys and girls than in children from the younger age groups. The highest borderline total cholesterol level was found in children aged 10 years. Older children had the lowest borderline HDL-cholesterol values. As the prevention of coronary disease should already start in childhood, it is necessary to assess the mean and borderline lipoprotein levels in school children. The present work, together with the previously published papers from different parts of Poland, may contribute to establishing normal values for our country.
