[Lipid content in the blood serum of children and adolescents]

Content of lipids was studied in blood serum of 350 practically healthy children and teen-agers of both sexes at the age of 5-14 living in Moscow. The mean content of cholesterol was 169 mg per 100 ml in blood serum of the children; it did not depend on the age and sex. The upper level of the normal cholesterol content was about 205 mg/100 ml. Concentration of triglycerides was gradually increased in children blood serum with an increase in age from 51 mg/100 ml in 5-9 year old children up to 68 mg/100 ml at the age of 10-14 years and did not depend on sex. The increase in concentration of triglycerides correlated with an elevation in pre-beta-lipoprotein fraction in blood serum. The mean content of triglycerides was 60 mg/100 ml in 5-14 year old children. The upper level of normal triglyceride content was 115 mg/100 ml of blood serum for children of the age group studied.
