青春期子宫异常出血的影响因素分析

目的探讨湖北省荆州地区青春期子宫异常出血的影响因素,为降低青春期子宫异常出血发生率提供流行病学数据。方法选择2012年11月至2013年5月在荆州地区13所中学随机抽取年龄为12-16岁的初中在校女生5 000名（受试者）及其所填写的问卷为研究对象。采用自行设计的《青春期女生月经情况和一般情况调查表》,对受试者的基本信息（年龄、家庭地址、身高、体质量）,月经情况（月经初潮时间、月经周期、月经量）及其他因素（居住环境、经期护理、健康状况）等内容进行调查。此外,另自行设计《心理因素对青春期子宫异常出血影响调查表》,对因心理因素导致青春期子宫异常出血单独进行问卷调查。结果本调查问卷共计发放5 000份,剔除436名月经未来潮者所填写的问卷,回收有效问卷4 564份,问卷有效回收率为91.28%。根据本研究设定的子宫异常出血判断标准,子宫异常出血者为2 177名（47.69%）,月经正常者为2 387名（52.31%）。不同居住环境女生的子宫异常出血发生率比较,差异无统计学意义（χ^2=4.08,P〉0.05）;青春期女生不同身体健康状况（经期是否有感染史、结核、其他疾病与无疾病）、经期护理情况（护理良好与护理不良）及心理因素得分（≥35分与〈35分）的子宫异常出血发生率比较,差异均有统计学意义（χ^2=13.39,12.82,10.43;P〈0.05）。健康状况、经期护理及心理压力是子宫异常出血的危险因素（OR=3.65,95%CI：2.53-4.34,P〈0.05;OR=0.97,95%CI：0.86-1.09,P〈0.05;OR=0.57,95%CI：0.33-0.64,P〈0.05）。结论适量运动、均衡营养、良好心态和经期护理得当均能促进女性生理卫生健康。
