1利用腰围身高比预测有雄激素缺乏症的老年男性体内血清睾酮水平显示文摘老年男性血清睾酮的下降可能部分是由肥胖引起的,但是,还不能确定哪些肥胖相关的参数与睾酮水平最密切相关。我们研究过伴有雄激素缺乏症但健康状况良好的老年男性的年龄、肥胖和睾酮水平的关系。本研究中,我们从社区中募集了54岁以上无痛症或其他严重疾病的非吸烟男性做横向研究分析,测定身高,体重和腰围,并计算体质指数(BMI)和腰围身高比(WHt)。收集两个早上的血液样本,测量总睾酮,性激素结合球蛋白和促黄体激素。计算游离睾酮(cFT)。并对上述指标与肥胖参数之间的关系进行多元线性凹归分析。207名54-86岁之间的男性参与了此次研究。单因素分析结果表明腰围身高比与睾酮和游离睾酮的相关性明显高于体重和腰吲或体质指数。另外,对总睾酮和游离睾酮来说,体重和腰围以及身高都有重要意义(所有的P均小于0.05),身高值中加入体重和腰围值后,导致体重和腰用以及身高的回归系数都增加了,其中腰围呈负相关,身高呈正相关。总之,腰围身高比是预测健康但有雄激素缺乏症的老年男性的睾酮和游离睾酮最好的体质指标。Carolyn A Allan Roger E Peverill Boyd JG Strauss Elise A Forbes Robert I McLachlan 2011Asian Journal of Andrology2011,13,3:3
