Abstract
The lipoprotein components were studied in connection with a population study concerning the state of health and living habits of the elderly people in Turku, Finland. Serum levels of total cholesterol, high density lipoprotein (HDL) cholesterol, triglycerides, apolipoprotein A1 (apo A1) and apolipoprotein B (apo B) of the 347 elderly people (aged 65 years or over) were measured and those of low density lipoprotein (LDL) cholesterol were calculated. The levels of total cholesterol, LDL cholesterol and apo B were significantly higher in females than in males, and the concentrations decreased with advancing age. The concentrations of HDL cholesterol and apo A1 were significantly higher in females than in males but age had no effect. Serum triglycerides behaved differently in males and females; in females age had a significant increasing effect whereas in males no age effect was observed. The apo A1/apo B ratio did not differ between males and females. Reference values of serum lipids, lipoproteins and apolipoproteins of the elderly are suggested.
