Serum cholesterol and triglyceride levels in Norwegian adolescent school children.

The frequency distribution of serum cholesterol and triglycerides in 172 boys and 232 girls, 13--16 years, from four elementary schools in Oslo has been determined. The cholesterol values were significantly higher for girls 15--16 years than for boys of the same age group. In the case of triglycerides boys 15--16 years had significantly higher values than boys 13--14 years. Otherwise no statistically significant differences with regard to sex and age were observed. The 85th percentiles have been suggested as appropriate upper normal limits. In all groups the 85th percentile for plasma cholesterol was slightly below 6 mmol/l. The corresponding plasma triglyceride value was below 2 mmol/l.
