There is limited information on the association between metabolic syndrome components including body mass index (BMI) and type 2 diabetes mellitus in elderly Chinese population. Therefore, we investigated whether components of metabolic syndrome are associated with type 2 diabetes mellitus in elderly.
A total of 479 hospitalized patients (aged 65-95 years) with recently diagnosed type 2 diabetes mellitus were studied retrospectively in a cross-sectional study and compared with 183 subjects with prediabetes and 62 subjects without glucose metabolism abnormalities.
BMI (24.69±3.59 versus 23.92±3.08 and 23.56±3.25 kg/m), blood pressure, cholesterol, triglyceride, liver enzymes and prevalence of fatty liver were higher in patients with type 2 diabetes mellitus as compared with elderly subjects with prediabetes or normal glucose metabolism separately (all <0.05). Multivariable regression analysis showed that BMI was associated positively with insulin resistance and inversely with insulin sensitivity in type 2 diabetes mellitus group (all <0.05).
Higher BMI was associated with increased insulin resistance and decreased insulin sensitivity in elderly Asian population with type 2 diabetes mellitus.
关于包括体重指数(BMI)在内的代谢综合征各组分与中国老年人群2型糖尿病之间关联的信息有限。因此,我们调查了代谢综合征各组分是否与老年人的2型糖尿病相关。
在一项横断面研究中,对479例近期诊断为2型糖尿病的住院患者(年龄65 - 95岁)进行回顾性研究,并与183例糖尿病前期患者和62例无糖代谢异常的受试者进行比较。
与糖尿病前期或糖代谢正常的老年受试者相比,2型糖尿病患者的BMI(24.69±3.59 vs 23.92±3.08和23.56±3.25kg/m)、血压、胆固醇、甘油三酯、肝酶及脂肪肝患病率均更高(均P<0.05)。多变量回归分析显示,在2型糖尿病组中,BMI与胰岛素抵抗呈正相关,与胰岛素敏感性呈负相关(均P<0.05)。
在患有2型糖尿病的亚洲老年人群中,较高的BMI与胰岛素抵抗增加及胰岛素敏感性降低相关。
