探讨女性压力性尿失禁(stress urinary incontinence，SUI)发生与多种危险因素的关系。

采用整群抽样的方法，对634例不同年龄和不同职业的女性进行问卷调查。将219例压力性尿失禁发生的女性(SUI组)和415例正常对照女性(对照组)的人口学特征、妊娠、分娩损伤、泌尿生殖系统疾病，以及某些慢性病等因素资料，进行多因素非条件logistic回归分析。

对本组资料进行多因素非条件logistic回归分析发现，独立危险因素包括：第1胎体重、急产史、需使用雌激素治疗、饮酒、泌尿生殖系统感染史和子宫脱垂，与女性压力性尿失禁的发生呈正相关，且差异有显著意义。

第1胎胎儿过重、有急产史、雌激素缺乏、饮酒、有泌尿系统感染史和存在子宫脱垂，可能为广州地区女性压力性尿失禁发生的危险因素。
