High density lipoprotein and coronary artery disease risk factors in children with different lipoprotein profiles: Bogalusa Heart Study.
Serum high density lipoprotein-cholesterol (HDL-C) and apoprotein A-1 (apo A-1) profiles were examined in subgroups of children (n = 338), initially aged 2-14 years, whose earlier beta-lipoprotein cholesterol (beta-LPC) and pre-beta-lipoprotein cholesterol (pre-beta-LPC) measurements were in extreme percentiles of values from a biracial community. Relationships of HDL-C and apo A-1 to serum lipoprotein lipids, apoprotein B (apo B), subscapular skinfold thickness, fasting and 1/2 hr postglucose plasma insulin, and fasting and 1 hr postglucose plasma glucose and free fatty acids were examined. Clustering of several coronary artery disease risk factors in these children was observed. HDL-C levels tended to be low in children having high pre-beta-LPC levels and apo A-1 levels were low in boys having high pre-beta-LPC levels. Within beta- and pre-beta-LPC strata, differences were also observed with respect to race, but not sex, in the mean levels of both HDL-C and apo A-1. HDL-C and apo A.1 were related inversely to subscapular skinfold thickness and plasma insulin levels in all children except those with low levels of both beta-LPC and pre-beta-LPC. Ratios of low density lipoprotein-cholesterol/HDL-C and of apo B/apo A-1 were related positively with other coronary artery disease risk factors except in children having low levels of both beta-LPC and pre-beta-LPC. The magnitude of these associations was greater in whites than in blacks. These observations may help to identify, at an early age, children at high risk of developing coronary artery disease in adulthood.
