SERUM-LIPID AND LIPOPROTEIN PATTERNS OF BEIJING POPULATIONS FROM BIRTH TO SENESCENCE

The physiologic variations of serum lipids inthe residents in urban districts of Beijing from birth to senescence were studied by standardized me- thods. 15 208 were profiled for serum total choles- terol and 5 585 for high-density lipoprotein choles- terol and triglyceride. The average serum lipids of neonates were similar to those reported by other authors over the world. The characteristic sex and age differences of total and low-density lipoprotein cholesterol showed a striking similarity to those re- ported by the Lipid Research Clinic, USA, but the mean values were much lower in Beijing residents. However, Beijing boys and men had higher high- density lipoprotein cholesterol than American coun- terparts. The cholesterol and triglyceride reached top levels at age 60-80 and declined after 80. The nonagenarians had similar lipid levels as middle- aged adults. The definition of hypercholesterolemia was discussed briefly. The lipid risk level for coro- nary heart disease of Beijing populations was es- timated.
