To understand the prevalence of urinary incontinence (UI) and its related factors so as to develop a three-tier program for prevention of the disease.
A cross-sectional study was carried out in two townships of Jixian county, Tianjin, during July to November 2007. A total of 743 people aged 60 years and over were selected under cluster sampling, and all information were collected with a standardized structured questionnaire by face-to-face interview. All the data were analyzed with multivariate logistic regression method to explore the related factors for UI in the elderly.
The overall prevalence of UI was 33.38 percent among people aged 60 years and over in two townships. Risk factors for UI in men would include older age (OR = 1.39), occupation (OR = 5.00), awareness of UI (OR = 1.91), having in chronic respiratory diseases (OR = 2.23), prostate (OR = 11.47), neurological (OR = 11.76), or motor systems (OR = 2.48), while protective factors would include high educational level (taking primary school or below as control group), OR for the junior middle school group appeared to be 0.35, for senior middle school group it was 0.77, and of undergraduate group it was 0.53. Risk factors for UI in women would include older age (OR = 1.31), constipation (OR = 1.46), awareness of UI (OR = 1.94), increased body mass index (when normal weight group served as control group, OR in the overweight group was 1.03 and in the obesity group OR was 1.54), suffering from chronic respiratory diseases (OR = 4.84), diabetes mellitus (OR = 2.36), or motor system diseases (OR = 1.37), more gravidity (OR = 1.03), more parity (OR = 1.02), suffering from perinea laceration (OR = 1.72) and wound infection during delivery (OR = 1.65), while protective factors would include physical exercises (OR = 0.64).
Prevalence of UI was higher among the elderly people in rural areas of Jixian county, Tianjin. UI in the elderly might have been influenced by various factors which suggesting the intervention strategy should be targeted at those related factors as well as focusing on primary prevention.
了解尿失禁（UI）的患病率及其相关因素，以便制定三级疾病预防方案。
2007年7月至11月期间，在天津市蓟县的两个乡镇开展了一项横断面研究。采用整群抽样法选取了743名60岁及以上的老年人，通过面对面访谈，使用标准化结构化问卷收集所有信息。采用多因素logistic回归方法对所有数据进行分析，以探讨老年人尿失禁的相关因素。
两个乡镇60岁及以上人群中尿失禁的总体患病率为33.38%。男性尿失禁的危险因素包括年龄较大（OR = 1.39）、职业（OR = 5.00）、对尿失禁的认知（OR = 1.91）、患有慢性呼吸系统疾病（OR = 2.23）、前列腺疾病（OR = 11.47）、神经系统疾病（OR = 11.76）或运动系统疾病（OR = 2.48），而保护因素包括高学历（以小学及以下学历为对照组），初中组的OR为0.35，高中组为0.77，本科组为0.53。女性尿失禁的危险因素包括年龄较大（OR = 1.31）、便秘（OR = 1.46）、对尿失禁的认知（OR = 1.94）、体重指数增加（以正常体重组为对照组，超重组的OR为1.03，肥胖组的OR为1.54）、患有慢性呼吸系统疾病（OR = 4.84）、糖尿病（OR = 2.36）或运动系统疾病（OR = 1.37）、妊娠次数较多（OR = 1.03）、分娩次数较多（OR = 1.02）、会阴撕裂（OR = 1.72）和分娩时伤口感染（OR = 1.65），而保护因素包括体育锻炼（OR = 0.64）。
天津市蓟县农村地区老年人尿失禁患病率较高。老年人尿失禁可能受多种因素影响，提示干预策略应针对这些相关因素，并注重一级预防。
