Adequate pelvic floor support for the urethra is crucial for preventing stress urinary incontinence (SUI). Obesity is an established risk factor for SUI. This study aimed to explore the relationship between SUI and body composition, specifically focusing on muscle and fat mass.
This single-center, prospective, cross-sectional study enrolled women who visited the genitourinary clinic of Taipei City Hospital-Zhongxiao Branch between 1 February 2020 and 31 January 2021. SUI severity was classified according to the type of daily activity in which SUI occurred. Potential risk factors for SUI, including age, labor and history of hysterectomy, were also included. All participants underwent a bioelectric impedance analysis of their body composition. Independent t-tests and Pearson's χ-tests were used to compare the differences in continuous and categorical parameters between groups. Logistic regression analysis was used to characterize the predictive value of body composition for severe SUI.
Of the 256 included patients, 37 had severe SUI. The participants with severe SUI were older and were more likely to have undergone a hysterectomy. They also had a considerably higher prevalence of sarcopenia. In the univariate analysis, a sarcopenia diagnosis was associated with severe SUI. Furthermore, a history of hysterectomy correlated with severe SUI, although with borderline significance. In the multivariate analysis, a history of hysterectomy and lower trunk muscle mass index were found to be independent predictors of severe SUI.

尿道获得足够的盆底支持对于预防压力性尿失禁（SUI）至关重要。肥胖是SUI的既定风险因素。本研究旨在探讨SUI与身体成分之间的关系，特别关注肌肉和脂肪量。
这项单中心、前瞻性横断面研究纳入了2020年2月1日至2021年1月31日期间就诊于台北市立联合医院忠孝院区泌尿生殖科的女性。根据SUI发生的日常活动类型对其严重程度进行分类。SUI的潜在风险因素，包括年龄、分娩和子宫切除史也被纳入研究。所有参与者均接受了身体成分的生物电阻抗分析。采用独立t检验和Pearson卡方检验比较组间连续和分类参数的差异。采用逻辑回归分析来描述身体成分对严重SUI的预测价值。
在纳入的256例患者中，37例患有严重SUI。患有严重SUI的参与者年龄更大，更有可能接受过子宫切除术。他们的肌肉减少症患病率也显著更高。在单因素分析中，肌肉减少症的诊断与严重SUI相关。此外，子宫切除史与严重SUI相关，尽管具有临界显著性。在多因素分析中，子宫切除史和下躯干肌肉质量指数被发现是严重SUI的独立预测因素。
