女性BMI与子宫肌瘤发病率的相关性研究

Correlation between body mass index and incidence of hysteromyoma

目的探讨女性身体质量指数(BMI)与子宫肌瘤发病率之间的关系。方法采用回顾性病例对照研究方法,选择2016年3月至2017年2月在杭州市妇产科医院妇科门诊查体的2 593例女性为研究对象,根据BMI分成过轻(198例)、正常(1623例)、超重(622例)、肥胖组(150例)四组,分析BMI与子宫肌瘤发病率的相关性。结果在2 593例研究对象中诊断为子宫肌瘤的共663例,占25.57%。不同BMI组别患者子宫肌瘤发病率比较有显著性差异(χ2=21.038,P<0.001),随着BMI增加,子宫肌瘤发病率逐渐增加。Logistic回归分析显示BMI是影响子宫肌瘤发病的独立因素(OR=0.938,P<0.001)。结论超重与肥胖可增加子宫肌瘤的发生率。

Objective To examine the correlation between body mass index（BMI）and the incidence of hysteromyoma.Methods A total of 2 593 women who came to Hangzhou Women＇s Hospital for physical examination were recruited in this retrospective casecontrol study.According to BMI,they were divided into underweight group（n=198）,normal group（n=1 623）,overweight group（n=622）and obesity group（n=150）.The correlation between BMI and the incidence of hysteromyoma was analyzed.Results There were 663 cases（25.57%）diagnosed as hysteromyoma.There was significant difference in the incidence of hysteromyoma among different BMI groups（χ2=21.038,P 0.001）.And the incidence of hysteromyoma was positively correlated with BMI.Logistic regression analysis showed that BMI was an independent factor affecting the incidence of hysteromyoma（OR=0.938,P〈0.001）.Conclusion Overweight and obesity can increase the incidence of hysteromyoma.
