Waist circumference and abdominal adipose tissue distribution: influence of age and sex Export

@article{citeulike:2211528, abstract = {Background: The influence of age and sex on the distribution of abdominal adipose tissue for a given waist circumference (WC) is unclear. Objective: The objective was to investigate the influence of age and sex on total (TAAT), visceral (VAT), and abdominal subcutaneous (ASAT) adipose tissue for a given WC. Design: Body composition was assessed by whole-body magnetic resonance imaging in 147 younger men (< 50 y), 83 older men, 171 younger (premenopausal) women, and 80 older (postmenopausal) women with a wide range (16-40; in kg/m2) of body mass indexes. Results: Within each sex, the regression lines between WC and TAAT were not significantly different (P > 0.1) between younger and older groups. Collapsed across age groups, women had more TAAT for a given WC than did men; however, this difference was significantly reduced with increasing WC (P < 0.05). Within each sex, regression lines derived for WC and ASAT were not significantly different between younger and older groups (P > 0.1). Collapsed across age groups, women had 1.8 kg more ASAT for a given WC (P < 0.05) than did men across the range of WCs. Within each sex, older men and women had a significantly greater increase in VAT for a given WC (P < 0.05) than did younger men and women. Furthermore, independent of age group, the slopes for WC and VAT were significantly higher (P < 0.05) in men than in women. Conclusions: There are significant sex differences in TAAT, VAT, and ASAT for a given WC. Furthermore, the relation between WC and VAT is substantially influenced by age.}, author = {Kuk, Jennifer L. and Lee, Sojung and Heymsfield, Steven B. and Ross, Robert}, citeulike-article-id = {2211528}, citeulike-linkout-0 = {http://www.ajcn.org/cgi/content/abstract/81/6/1330}, citeulike-linkout-1 = {http://view.ncbi.nlm.nih.gov/pubmed/15941883}, citeulike-linkout-2 = {http://www.hubmed.org/display.cgi?uids=15941883}, day = {1}, journal = {Am J Clin Nutr}, keywords = {adipose, ageing, distribution, fat}, month = {June}, number = {6}, pages = {1330--1334}, posted-at = {2008-01-09 17:45:55}, priority = {2}, title = {Waist circumference and abdominal adipose tissue distribution: influence of age and sex}, url = {http://www.ajcn.org/cgi/content/abstract/81/6/1330}, volume = {81}, year = {2005} }
