摘要
目的探讨更年期妇女血清雌二醇(E_2)与胰岛素抵抗和卵巢功能衰退的关联。方法本研究选取2017年5-10月期间该院收治的80例更年期妇女为研究对象,根据血清E_2水平分组,将血清E_2水平<80 pmol/L的受试者33例纳入低E_2组,将血清E_2水平≥80 pmol/L的受试者47例纳入高E_2组。比较两组卵巢功能指标、胰岛素抵抗指数、血清单胺氧化酶(MAO)活性以及更年期症状。结果低E_2组受试者E_2水平明显低于高E_2组,卵泡刺激素(FSH)水平明显高于高E_2组、黄体生成素(LH)水平明显高于高E_2组(P<0. 05)。低E_2组受试者胰岛素抵抗指数明显高于高E_2组受试者(5. 28±0. 63 vs.4. 02±0. 55,P<0. 05)。两组受试者体重、BMI指数、绝经年龄及绝经时间差异均无统计学意义(P>0. 05)。低E_2组受试者潮热出汗、失眠、容易疲乏、暴躁易怒、胸闷心悸、性欲减退、外阴不适评分以及更年期症状总评分均明显高于高E_2组(P<0. 05)。低E_2组受试者MAO活性明显高于高E_2组(39. 68±6. 17 vs. 28. 42±3. 85,P<0. 05)。多因素Logistic回归分析结果显示,更年期妇女血清E_2表达水平与胰岛素抵抗指数、FSH与LH水平及MAO活性相关(P<0. 05),与BMI指数、绝经年龄、绝经时间及体重无显著相关性(P>0. 05)。结论更年期妇女血清E_2水平与胰岛素抵抗及卵巢功能衰退密切相关。
