体质量管理对肥胖型多囊卵巢综合征女性的内分泌激素水平和辅助生育结局的影响

目的 探讨体质量管理对肥胖型多囊卵巢综合征（PCOS）不孕症女性的内分泌激素水平和辅助生育结局的影响。方法 收集62例进行辅助生殖技术（ART）治疗的肥胖型PCOS不孕症患者的临床资料,选择接受常规辅助生育治疗的28例患者为对照组,在常规辅助生育治疗的基础上接受定期体质量管理的34例患者为体质量管理组。比较2组患者的内分泌激素水平和辅助生育结局。结果 减重后,体质量管理组肥胖型PCOS患者的体质量、BMI、体脂、腰臀均较减重前以及对照组降低（P均< 0.05）。减重后,体质量管理组肥胖型PCOS患者的空腹胰岛素[（13.2 ± 4.2）mU/L]均较减重前[（21.5 ± 6.1）mU/L]以及对照组[（20.3 ± 5.8）mU/L]降低（P < 0.001）。体质量管理组的人工授精累积临床妊娠率（25% vs. 13%）和首次胚胎移植后的临床妊娠率（61% vs. 39%）略高于对照组,但组间比较差异均无统计学意义（P均> 0.05）。结论 体质量管理可以有效降低肥胖型PCOS不孕症患者的BMI、空腹胰岛素水平,可能潜在地改善其辅助生育的妊娠结局。

Effect of weight loss on endocrine hormonal levels and assisted reproductive outcomes of obese PCOS women

Objective To investigate the effect of weight loss on the endocrine hormonal levels and assisted reproductive outcomes of women with obese polycystic ovarian syndrome （PCOS）. Methods Clinical data of 62 obese women with PCOS receiving assisted reproductive techniques （ART） were collected. All women were divided into the control （n = 28） and weight loss groups （n = 34）. In the control group, routine ART was given, and routine ART combined with regular weight loss interventions were delivered in the weight loss group. The endocrine hormonal levels and assisted reproductive outcomes were statistically compared between two groups. Results After weight loss, body weight, body mass index （BMI）, body fat and waist-to-hip ratio of obese PCOS women were significantly reduced compared with those before weight loss and those in the control group （all P < 0.05）. In the obese PCOS women, the fasting insulin level after weight loss was （13.2±4.2） mU/L, significantly lower compared with （21.5±6.1） mU/L before weight loss and （20.3±5.8） mU/L in the control group （both P < 0.001）. The accumulated clinical pregnancy rates after intrauterine insemination （25.0% vs. 13.3%） and clinical pregnancy rates after the first embryo transfer （61.1% vs. 38.5%） in the weight loss group were slightly higher than those in the control group without statistical significance （both P > 0.05）. Conclusion Weight loss can significantly reduce the BMI and fasting insulin level, and might potentially improve assisted reproductive outcomes in obese PCOS women.
