摘要
目的 探讨江苏南京地区人群中体重指数、腰臀比、腹围这 3种人体测量值以及脂代谢指标、糖代谢指标与瘦素的相关性。方法 将 188名南京地区长期居住汉族成人按BMI及糖尿病诊断标准分为正常组、肥胖组和糖尿病组 ,均检测身高、体重、腰围、腹围、臀围 ,并测定空腹血清胆固醇、甘油三酯、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、载脂蛋白A、载脂蛋白B和空腹血糖 (FPG)、真胰岛素 (TI)、免疫反应性胰岛素 (IRI)和瘦素 ,以ISI1=1/ (FPG×TI)和ISI2 =1/ (FPG×IRI)作为胰岛素敏感指数 ,对瘦素与 3种人体测量值和脂代谢指标及胰岛素抵抗的相关性进行分析。结果 对空腹血浆瘦素水平起决定作用的是性别的差异 (女性为男性的 4倍 ) ;其次是体重指数 (r =0 .5 7,P<0 .0 0 1) ;真胰岛素与瘦素呈现显著正相关 (r =0 .32 ,P <0 .0 0 1) ,ISI1与瘦素呈现显著负相关 (r =- 0 .39,P <0 .0 0 1) ,未发现血脂指标与瘦素有任何相关性。结论 南京地区人群中 ,空腹瘦素水平是由性别、肥胖程度 (主要是体重指数 )决定的 ,同时与胰岛素抵抗密切相关
