Sex differences in high density lipoprotein cholesterol among low-level alcohol consumers

The purpose of this study was to examine high density lipoprotein cholesterol (HDL-C) levels in a sample of community-living women and men who consumed 1 drink of alcohol/day or less. Self-reports of alcohol consumption and clinical assessments of plasma lipid and lipoprotein levels were obtained twice, at 12 months apart. Among men, consumption of 1 drink/day or less was unrelated to levels in HDL-C. In contrast, among women alcohol consumption throughout this relatively low consumption range was positively associated with HDL-C levels. These findings indicate that the association of alcohol and higher levels of HDL-C may occur at lower intakes of alcohol in women than in men.
