目的了解2型糖尿病(T2DM)家族史对代谢健康超重/肥胖(metabolically healthy overweight/obese,MHO)人群的胰岛素敏感性及胰岛β细胞功能的影响。方法自2004年1月至2007年12月从2058名T2DM家系成员中选取既往无血糖异常的一级亲属435名以及无T2DM家族史、无血糖异常的配偶116例。根据体质指数[BMI(18.5 kg/m2≤BMI<25 kg/m2)和超重及肥胖(BMI≥25 kg/m2)]及代谢异常情况将受试者分为一级亲属中代谢健康的正常体重组(A组)、超重肥胖组(B组)和代谢异常超重肥胖组(C组),配偶中代谢健康的正常体重组(A1组)、超重肥胖组(B1组)和代谢异常超重肥胖组(C1组)。以稳态模型(HOMA)胰岛素抵抗指数(HOMA?IR)评估胰岛素敏感性,葡萄糖处置指数(DI)评估胰岛β细胞功能[DI 1=HOMA?β/HOMA?IR,DI2=ΔI30/ΔG30/HOMA?IR,其中ΔI30/ΔG30为葡萄糖耐量试验(OGTT)中胰岛素30 min和空腹时的差值(ΔI30)与血糖30 min和空腹的差值(ΔG30)的比值]。正态分布数据采用独立样本t检验分析,偏态分布数据用非参数检验(Mann?Whitney U检验)分析,通过协方差分析校正年龄因素的影响。结果(1)比较一级亲属各组,B组[3.11(1.11,5.49)]的HOMA?IR高于A组[2.42(0.67,5.99)],但低于C组[3.80(0.50,16.02),均P<0.05]。B组DI1[47.17(29.83,88.93)]低于A组[56.07(30.00,197.90),U=1582,P<0.05],但高于C组[38.27(2.46,225),U=2041,P<0.05]。B组的DI2[5.02(1.83,22.51)]与A组之间差异无统计学意义,但显著高于C组[2.90(0.07,25.21),U=1817,P<0.01]。(2)比较一级亲属与配偶组,与B1组[2.02(1.44,6.10)]、A1组[2.28(1.07,7.44)]相比,B组[3.11(1.11,5.49)]的HOMA?IR高于前二者(U=22、495,均 P<0.05),DI1[47.17(29.83,88.93)]低于 A1组[60.00(30.00,130.81),U=22,P<0.05]。结论 T2DM家族史可能会降低代谢健康超重肥胖人群的胰岛素敏感性。

Objective To investigate the impact of family history of type 2 diabetes mellitus (T2DM) on pancreatic β-cell function and insulin sensitivity in metabolically healthy overweight/obese individuals. Methods A total of 435 first?degree relatives of patients with T2DM and 116 spouses without family history of T2DM or impaired glucose tolerance were selected. The individuals were divided into six groups: metabolically healthy normal weight of first-degree relatives (group A), metabolically healthy overweight/obese of first?degree relatives (group B), at?risk overweight/obese of first?degree relatives (group C), metabolically healthy normal weight of spouses (the control group, group A1), metabolically healthy overweight/obese of spouses (group B1), at?risk overweight/obese of spouses (group C1) according to body mass index (BMI) and metabolic status. We used homeostasis model assessment (HOMA?IR) and glucose disposition index (DI1 and DI2) to evaluate insulin sensitivity and pancreatic β?cell function, respectively. T?test was used to measure normal ditribution date, while Mann whitney U test was used to test Skewness <br> distribution data. Covariance analysis was used to exclude the influence of age. Results (1) In the group B, HOMA-IR(3.11(1.11,5.49)) was higher compared to the group A(2.42(0.67,5.99), P<0.05), and lower compared to the group C(3.80(0.50,16.02), P<0.05). Simultaneously, DI1(47.17(29.83,88.93)) was lower compared to the group A(56.07(30.00,197.90), P<0.05) and higher compared to the group C(38.27(2.46, 225)). DI2(5.02(1.83,22.51)) was higher significantly when compared to the group C(2.90(0.07,25.21), P<0.01), but no statistical significance compared to the group A. (2) When comparing with the B1(2.02(1.44, 6.10)) and A1(2.28(1.07,7.44)) groups, HOMA-IR in the group B (3.11(1.11,5.49)) was higher (P<0.05). However, no statistical significance was found in DI2, and DI1(47.17(29.83,88.93)) was only found significant when comparing with the A1 group(60.00(30.00,130.81)). Comparing the group A and A1 group, there were no statistical significance in HOMA?IR, DI1 or DI2. Conclusion Family history of T2DM may decrease insulin sensitivity of MHO individuals.
