Serum Lipid and Lipoprotein Concentrations in a Norwegian Population Sample

Serum lipids and electrophoretically determined lipoprotein concentrations have been analysed in 168 healthy subjects (118 males and 50 females) belonging to two different age groups. An increase in serum lipid and lipoprotein levels with age was seen. No difference was found between the concentrations in young males and females. Higher concentrations of β‐ and pre‐β‐lipoproteins and lower level of α‐lipoproteins were found in males than in females in the age group 40–59. Serum cholesterol values were determined in a series of 828 males and 382 females of different ages (15–69 years). In males the mean cholesterol values increased from 197 mg/100 ml in the age group 15–19 to 280 mg/ 100 ml in the age group 40–49. Means close to the latter age value were found also in the higher age groups. In females, mean cholesterol value increased throughout life from 208 mg/100 ml in young females to 337 mg/ 100 ml in those aged 60–69.
