This report describes the age-race specific distribution of fatty acids in samples of adipose tissue taken from both the perirenal and buttock areas of 406 men autopsied in a community pathology study. This analysis of fatty acid composition of adipose tissue is part of a comprehensive investigation of atherosclerosis and coronary heart disease in a community setting. The findings from analysis of fatty acids are expressed as mass percentage of all fatty acids in adipose tissue triglyceride. For each age-site subgroup, white men tended to have higher mean percentages of myristic acid and palmitoleic acid than did black men. The converse was found for stearic acid. In the younger age groups only, the whites showed a higher mean percentage of linoleic acid than the blacks in adipose tissue from both sites. Age was associated with a decrease in mean percentage of stearic acid and an increase in mean percentage of oleic acid and palmitoleic acid in both races. The older age group had a lower mean percentage of linoleic acid than the younger age groups. The mean percentages of myristic, palmitic, and stearic acids were higher in perirenal tissue, while the mean percentages of palmitoleic and oleic acids were higher in buttock adipose tissue in both races.
本报告描述了在一项社区病理学研究中对406名男性尸体进行尸检时，从肾周和臀部区域采集的脂肪组织样本中脂肪酸的年龄-种族特异性分布情况。对脂肪组织脂肪酸组成的这一分析是社区环境中动脉粥样硬化和冠心病综合调查的一部分。脂肪酸分析结果以脂肪组织甘油三酯中所有脂肪酸的质量百分比表示。对于每个年龄-部位亚组，白人男性的肉豆蔻酸和棕榈油酸平均百分比往往高于黑人男性。硬脂酸的情况则相反。仅在较年轻年龄组中，白人在两个部位的脂肪组织中亚油酸平均百分比高于黑人。年龄与两个种族中硬脂酸平均百分比降低以及油酸和棕榈油酸平均百分比增加有关。老年组亚油酸平均百分比低于年轻年龄组。两个种族中，肾周组织中肉豆蔻酸、棕榈酸和硬脂酸的平均百分比更高，而臀部脂肪组织中棕榈油酸和油酸的平均百分比更高。
