[Age and dynamics of the chief blood lipid indices among the adult population of Leningrad].

Variations in the blood levels of total cholesterol (C), triglycerides, low and high density lipoprotein cholesterol ( LDLPC , HDLPC ) and atherogenicity ratio were examined over time in 4841 men and 2323 women living in Leningrad. The mean values of the parameters studied were established for different age groups. Considerable differences were revealed in the blood lipid profile in men versus women. Higher levels of HDLPC and lower concentrations of LDLPC in women under 50 as compared with age-matched men account for a later development and milder course of coronary heart disease in premenopausal women.
