Plasma high-density lipoprotein cholesterol comparisons in black and white populations. The Lipid Research Clinics Program Prevalence Study.


High-density lipoprotein (HDL) cholesterol distributions were compared among 191 black and 1341 white males and 233 black and 1088 white females, ages 5-44 years, examined in five of the Lipid Research Clinic (LRC) population-based surveys. Mean HDL cholesterol was higher in blacks than whites in each 5-year age group for males and in seven of the eight age groups for females. The black-white mean HDL cholesterol difference was greater for males than females at each age studied. Mean HDL cholesterol was 4.8 mg/dl higher in black than white males ages 5-19 years, after statistical adjustment for age, Quetelet index and plasma total cholesterol differences between blacks and whites (p < 0.001); mean HDL cholesterol was 9.5 mg/dl higher in black than white adult males ages 20-44 years. Adjustment for levels of plasma triglyceride, which were lower in blacks than whites, reduced but did not eliminate the magnitude of the statistical significance in black-white differences: The adjusted means were 2.9 mg/dl higher in black children and 7.9 mg/dl higher in black adults. The finding of higher levels of HDL cholesterol in black males persisted after additional adjustment for alcohol consumption, smoking and educational levels. Adult U.S. black males have lower and black females have higher coronary heart disease mortality rates than their white peers. The magnitude of the black-white difference in HDL cholesterol for males in the LRC studies was within the range associated with coronary heart disease incidence reported in other studies.
