目的:探讨老年2型糖尿病患者体重指数(BMI)与胰岛β功能状态及胰岛素抵抗(RI)的关系。方法:调查对象为2006年4月~2008年7月入我接受健康体检的成都地区离退休干部。采用1999年WHO糖尿病诊断标准,以129例已确诊T2DM患者为观察对象,根据体重指数(BMI)分为两组:肥胖组(含超重)(BMI≥25)66例,均为男性;非肥胖组(BMI lt;25)63例,其中3例为女性(无统计学意义),并与19例正常对照组进行对比研究。以氧化酶法测定空腹血葡萄糖(FBG),酶联免疫法测胰岛素(INS)及C肽(CP)水平等参数。用HOMA公式计算胰岛素抵抗(IR)和β细胞功能指数(BCI)。采用SPSS软件进行方差分析(ANOVA),分析3组间各指标的差异显著性x-±S表示。结果:三组经HOMA 公式计算的IR值为对照组(3.0±1.3)、非肥胖组(4.6±4.0)、肥胖组(5.2±6.2)依次递增,但各组间无显著性差异。HOMAβ细胞功能指数为非肥胖组(82.06±84.1)、肥胖组(138.4±179.6)、对照组(226.5±236.8)依次递增,各组间均有显著性差异(P lt;0.01~0.05)。 结论:老年2型糖尿病患者普遍存在β细胞功能减退,尤其是非肥胖组;同时也具有胰岛素抵抗,主要是肥胖组。表明BMI对老年糖尿病患者胰岛β细胞功能有影响,肥胖患者β细胞分泌能力加强,负担加重,功能受损,胰岛素抵抗明显。
