To assess prevalence of Urinary Incontinence (UI) during the late third trimester and three months postpartum period in King Chulalongkorn Memorial Hospital.
The present study population comprised > or = 36 weeks singleton pregnant women attending the ANC at King Chulalongkorn Memorial Hospital between 2009 and 2010. Questionnaire was developed from International Continence Society Questionnaire, which consisted of two parts, (1) socioeconomic demographic, characteristics related to UI, and (2) obstetric characteristic, UI experienced after delivery. Validity and reliability of the questionnaire were tested (Cronbach's alpha = 0.8). Chi-square, t-test, Pearson correlation McNemar test, and Binary logistic regression were used for comparison.
The majority of the participants (93.8%) were aged between 20 and 39 years old. The prevalence of UI during late pregnancy and three months postpartum were 53.8% and 7.8%, respectively. This difference reached statistical significance (p < 0.001). There were 53.5% of stress UI, 20% of urge incontinence, and 7.8% of mixed type UI during late third trimester, whereas only stress UI was found in three months postpartum period. The only risk factor for late antenatal and early postpartum UI was high pre-pregnancy BMI (OR 2.3; 95% CI 1.38-3.85, p < 0.001 and OR 3.3; 95% CI 1.8-6.0, p < 0.001, respectively).
The prevalence of UI was quite high during the late third trimester (53.8%) and decreased significantly three months postpartum (7.8%). Pre-pregnancy BMI is the only risk factor for developing UI in late antenatal and early postpartum period. This may help obstetricians for prediction and prevention of UI during pregnancy and postpartum in high-risk group.
评估朱拉隆功国王纪念医院孕晚期及产后三个月期间尿失禁（UI）的患病率。
本研究人群包括2009年至2010年期间在朱拉隆功国王纪念医院接受产前检查的≥36周单胎孕妇。问卷由国际尿失禁学会问卷编制而成，包括两部分：（1）社会经济人口统计学、与尿失禁相关的特征；（2）产科特征、产后经历的尿失禁。对问卷的效度和信度进行了测试（Cronbach's α = 0.8）。采用卡方检验、t检验、Pearson相关分析、McNemar检验和二元逻辑回归进行比较。
大多数参与者（93.8%）年龄在20至39岁之间。孕晚期和产后三个月尿失禁的患病率分别为53.8%和7.8%。这种差异具有统计学意义（p < 0.001）。孕晚期压力性尿失禁占53.5%，急迫性尿失禁占20%，混合性尿失禁占7.8%，而产后三个月仅发现压力性尿失禁。产前晚期和产后早期尿失禁的唯一危险因素是孕前高体重指数（OR分别为2.3；95%CI 1.38 - 3.85，p < 0.001和OR 3.3；95%CI 1.8 - 6.0，p < 0.001）。
孕晚期尿失禁的患病率相当高（53.8%），产后三个月显著下降（7.8%）。孕前体重指数是产前晚期和产后早期发生尿失禁的唯一危险因素。这可能有助于产科医生对高危人群孕期和产后尿失禁进行预测和预防。
