【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更多还原

【Abstract】 Objective To assess the association of obesity, serum lipid levels and insulin resistance with leptin in Nanjing population. Methods One hundred and eighty eight subjects aged 22～81 years in Nanjing were divided into three groups according to BMI and dignosis criteria of diabetes: normal group, obese group and diabetes group. Their weight, height, waist, abdomen and hip circumferences were measured. Total cholesterol, triglycerides, low density lipoprotein cholesterol, high density lipoprotein cholesterol, apoA, apoB, fasting plasma glucose (FPG), true insulin (TI), immunoreactive insulin (IRI) and leptin were also measured. ISI 1=1/(FPG×TI) and ISI 2=1/(FPG×IRI) as insulin sensitivity indexes were used to analyse the relation between leptin and insulin resistance. Results Fasting serum leptin level was associated with sex (four fold as high in women as that in men). BMI was the second strongest determinant of leptin. Leptin was positively correlated with TI (r=0.32, P<0.001), and was negatively correlated with ISI 1 (r=-0.39, P<0.001), none of serum lipid indexes was found to be related to fasting leptin. Multiple linear regression analysis also proved the above results. Conclusion Fasting serum leptin level was associated with sex and body mass index, and strongly related to insulin resistance in Nanjing urban population.更多还原
