Differences between black and white men in correlates of high density lipoprotein cholesterol.
Although socioeconomic status has been positively related to levels of high density lipoprotein (HDL) cholesterol in white Americans, limited evidence suggests that an inverse association may exist among blacks. These associations were further examined using data collected in 1985-1986 from 3,562 white and 500 black men who ranged in age from 31 to 45 years. Overall, mean levels of HDL cholesterol were 8 mg/dl higher among blacks than among whites and, in each group, levels were related positively to alcohol consumption and negatively to Quetelet index and cigarette smoking. A statistically significant interaction, however, was observed between race and educational achievement: no association was seen between educational achievement and levels of HDL cholesterol among white men, but there was an inverse association among blacks. For example, a 13 mg/dl (55 vs. 42 mg/dl) difference in levels of HDL cholesterol was observed between black and white men who did not complete high school, but only a 3 mg/dl black excess (47 vs. 44 mg/dl) was seen among college graduates. About 40 percent of this reduction could be attributed to the effects of cigarette smoking, alcohol consumption, and relative weight. These results indicate that the higher levels of HDL cholesterol frequently found among black men in the United States may not apply to all social strata. Other characteristics, such as physical activity and diet, may account for the differing race-specific associations with educational achievement.
