摘要
目的探讨非肥胖型和肥胖型多囊卵巢综合征(PCOS)患者的糖代谢特征。方法回顾性分析2008年3月至2011年7月就诊的118例PCOS患者的临床资料,以及糖耐量、胰岛素释放试验的结果,按体质量指数(BMI)分为非肥胖组65例(BMI〈25kg/m^2)和肥胖组53例(BMI≥25kg/m^2),比较两组患者口服糖耐量试验(OGTT)结果,以及空腹血糖调节受损(IVC)、糖耐量减低(IGT)和2型糖尿病的发生率。结果(1)血糖水平:空腹及服糖后30、60、120、180min,非肥胖组分别为(5.2±1.1)、(8.5±2.8)、(8.1±2.4)、(6.3±2.0)、(4。8±1.5)mmoL/L,肥胖组分另U为(5.4±0.9)、(9.1±1.8)、(9.3±0.6)、(7.6±1.0)、(5.4±0.8)mmol/L,两组各时间点血糖水平比较,差异均有统计学意义(t值分别为-6.125、-4.005、-6.074、-6.751、-4.512,P均〈0.01)。(2)胰岛素水平:空腹及服糖后30、60、120rain,非肥胖组分别为(8±4)、(55±21)、(65±14)、(45±18)mU/L,肥胖组分别为(13±8)、(85±30)、(105±54)、(76±46)mU/L,两组各时间点比较,差异均有统计学意义(t值分别为-17.024、-12.540、-15.791、-16.149,P均〈0.01);但服糖后180min两组胰岛素水平比较,差异无统计学意义(P〉0.05)。(3)糖代谢异常发生率:非肥胖组和肥胖组分别为13.85%(9/65)和24.53%(13/53),两组比较差异有统计学意义(X^2=18.446,P〈0.01);非肥胖组和肥胖组2型糖尿病发生率分别为1.54%(1/65)和7.55%(4/53),两组比较差异也有统计学意义(X^2=16.005,P〈0.01)。结论肥胖型较非肥胖型PCOS患者更易发生糖代谢紊乱。
Objective To investigate characteristics of glucose metabolism of non-obese and obese women with polycystie ovary syndrome(PCOS). Methods From March 2008 to July 2011,118 PCOS patients were enrolled in this study and were divided into 53 cases (body mass index(BMI) ≥25 kg/m^2) in obese group and 65 cases (BMI 〈25 kg/m^2) in non-obese group. Participants' clinical data,glucose tolerance and insulin release test results were retrospectively reviewed. The prevalence of type 2 diabetes mellitus (T2DM), results of oral glucose tolerance test, impaired fasting glucose ( IFG), impaired glucose tolerance (IGT) were compared between the two groups. Results (1)Blood glucose levels:at the time points of 30,60,120 and 180 minutes, the levels of fasting glucose were ( 5. 2 ± 1.1 ), ( 8. 5 ± 2. 8 ), ( 8. 1±2.4 ), ( 6. 3 ± 2.0 ) and ( 4. 8 ± 1.5 ) mmol/L in non-obese group and ( 5.4±0. 9 ), (9. 1 ± 1.8 ), (9. 3 ± 0. 6), (7. 6±1.0) and (5.4 ± 0. 8 ) mmol/ L in obese group. Statistical difference was observed between obese and non-obese groups at each time point (t = -6. 125, -4. 005, -6. 074, -6. 751 and -4. 512 respectively,P 〈0.01). (2)The level of insulin:at the time points of 30,60 and 120 rain,the level of fasting insulin were ( 8 ± 4 ), ( 55 ± 21 ), ( 65 ± 14 ) and ( 45 ± 18 ) mU/L in non-obese group and ( 13 ± 8 ), (85 ± 30), ( 105 ± 54) and (76 ± 46 ) mU/L in obese group. There were significant statistical difference between the two groups at each time point (t = -17. 024, -12. 540, - 15. 791 and - 16. 149 respectively, P 〈 0. 01 ). However, at the time point of 180 minutes, the level of insulin did not exhibit significant difference between obese and non-obese groups ( P 〉 0. 05 ). ( 3 ) The prevalence of abnormal glucose metabolism: The rates of IGT were 13.85% (9/65) in non-obese group and 24. 53% ( 13/53 ) in obese group, which also showed remarkable difference ( X^2 = 18.446, P 〈 0. 01 ). The rates of T2DM were 1.54% (1/65) in non-obese group and 7. 55% (4/53) in obese group,which reached significant difference (X^2= 16. 005, P 〈 0.01 ). Conclusion Abnormal glucose metabolism was observed more freauently inoverweight or obese PCOS women.
