Abstract

We used nondenaturing polyacrylamide gradient gel electrophoresis to examine the associations of age, adiposity, alcohol intake, and exogenous estrogen with high-density lipoprotein (HDL) subclasses in 427 members of 51 principally Mormon kindreds. The absorbency of protein stain was used as an index of mass concentrations at intervals of 0.01 nm within five HDL subclasses: HDL3c (7.2 to 7.8 nm), HDL3b (7.8 to 8.2 nm), HDL3a (8.2 to 8.8 nm), HDL2a (8.8 to 9.7 nm), and HDL2b (9.7 to 12 mm). Age and alcohol intake were obtained from questionnaires, and body mass index was computed from clinic measurements as weight (kg)/height (m)2. The results suggest that HDL3b concentrations were higher after menopause than before. Adult men (> or = 18 years old) had significantly higher HDL3c and HDL3b and significantly lower HDL2b and HDL2a levels than younger boys. Compared with the women, adult men had higher levels of HDL3c and HDL3b and lower levels of HDL2b, HDL2a, and larger-diameter HDL3a particles. There were no significant differences between the HDL profiles of women and younger boys, suggesting that divergence in HDL occurs during puberty. Eighty-eight percent of the increase in HDL associated with estrogen replacement in postmenopausal women occurred within HDL3a and HDL2a. Reported alcohol intake in adult men correlated with two HDL regions: one within the HDL2b region and a second within the HDL3a/2a region, whereas in women the positive correlation between alcohol and HDL levels was within the HDL2b region only. In both men and premenopausal adult women, increasing levels of body mass index were associated with higher levels of HDL3b and lower levels of HDL2b.(ABSTRACT TRUNCATED AT 250 WORDS).
