Abstract
Coronary heart disease (CHD) has its origin in childhood. High cholesterol levels measured in children and adolescents are indicative of concurrent atherosclerotic changes and probably predict adult coronary heart disease. We review here the relevance of screening children, adolescents or young adults for serum lipid levels in order to efficiently prevent premature adult coronary heart disease. Data is presented in the light of the large Cardiovascular Risk in Young Finns study and other studies. The authors do not recommend universal screening strategies because of (i) the limited predictive power of serum lipid levels on an individual level, (ii) the limited knowledge on the safety of interventive measures on the growing child, and (iii) the limited knowledge on the ethical aspects of screening (labelling). However, the importance of measuring serum lipids to detect familial dyslipidaemic disorders such as familial hypercholesterolaemia, is stressed. The selection of children or adolescents for serum lipid measurements should be made on the basis of family history of early CHD or dyslipidaemia.
