Title: Population frequency distributions of HDL, HDL(2), and HDL(3) cholesterol and apolipoproteins A-I and B in healthy men and women and associations with age, gender, hormonal status, and sex hormone use: the Stanford Five City Project. Author: Gardner CD, Tribble DL, Young DR, Ahn D, Fortmann SP. Journal: Prev Med; 2000 Oct; 31(4):335-45. PubMed ID: 11006058. Abstract: BACKGROUND: The purpose of this study is to present population-based frequency distribution data for several lipoprotein-related variables and to examine their associations with gender, age, menopausal status, and sex hormone use. METHODS: High-density lipoprotein cholesterol (HDL-C), HDL(2)-C, HDL(3)-C, apolipoprotein (Apo) A-I, and Apo B were measured in a population-based sample of 1, 027 healthy adults from four California cities who participated in the 1989-1990 survey of the Stanford Five City Project. These data were examined cross-sectionally with sociodemographic and other related variables. RESULTS: Relative to men, all of the HDL-related parameters-HDL-C, HDL(2)-C, HDL(3)-C, Apo A-I-were significantly higher and Apo B levels were significantly lower among women (P < 0. 001). Menopausal status was not associated with HDL-related parameters, but Apo B levels were higher in post- versus premenopausal women (P < 0.001). Among women, HDL-C and Apo A-I levels were higher in oral contraceptive and estrogen replacement therapy users (P = 0.003). Most of the significant findings remained statistically significant after adjusting for age, body mass index, smoking, energy expenditure, and alcohol intake. CONCLUSIONS: These population-based data indicate that gender, menopausal status, and the use of sex hormones among women are associated with differential levels of one or more of HDL-C, HDL(2)-C, HDL(3)-C, Apo A-I, and Apo B, independent of age and a broad set of lifestyle factors.[Abstract] [Full Text] [Related] [New Search]
