[Cholesterol values in a cohort of adolescents in Sør Trøndelag]

Over a four-year period total serum cholesterol values were obtained from all 7th grade lower secondary school students (age 13) in a municipality in Norway. The 139 girls included in the survey had a mean value of 4.24 mmol/l (95% CI 4.12-4.37), and the 160 boys 4.11 mmol/l (95% CI 3.98-4.23), which is slightly lower than other Nordic surveys. Some students from one year were also measured in the 9th and 11th grades. One student was found to have familial hyper-cholesterolemia, and this value was excluded from the reference material. Screening for this disease among students is not recommended.
