This study sought to examine the effect of the appendicular skeletal muscle index (ASMI) and trunk muscle index (TMI) on the likelihood of stress urinary incontinence (SUI) among female adults.
This investigation utilized data from the National Health and Nutrition Examination Survey from 2001 to 2006 and 2011-2018. To evaluate the impact of ASMI and TMI on the likelihood of SUI, the study utilized restricted cubic splines (RCS) and weighted multivariable logistic regression models. Subgroup and interaction analyses were conducted to investigate how other covariates influenced their relationship.
In total, 11,168 female adults participated in the analysis. Multivariable logistic regression analysis revealed that high TMI was associated with a decreased likelihood of SUI (OR = 0.34; 95% CI: 0.16-0.75; = 0.013). ASMI was not correlated with the likelihood of SUI. RCS analysis demonstrated a linear correlation between TMI and SUI risk, showing a decreasing trend in SUI risk as TMI increases ( for overall <0.001, for nonlinearity = 0.73).
Our study results showed that there was no association between ASMI and the risk of SUI, while a high TMI reduced the risk of SUI. This suggested that the ratio of muscle mass and BMI in different body regions has varying effects on SUI.
本研究旨在探讨女性成年人中四肢骨骼肌指数（ASMI）和躯干肌肉指数（TMI）对压力性尿失禁（SUI）发生可能性的影响。
本研究使用了2001年至2006年以及2011年至2018年的国家健康与营养检查调查数据。为评估ASMI和TMI对SUI发生可能性的影响，本研究采用了受限立方样条（RCS）和加权多变量逻辑回归模型。进行亚组分析和交互分析以研究其他协变量如何影响它们之间的关系。
共有11168名女性成年人参与了分析。多变量逻辑回归分析显示，高TMI与SUI发生可能性降低相关（OR = 0.34；95% CI：0.16 - 0.75；P = 0.013）。ASMI与SUI发生可能性无关。RCS分析表明TMI与SUI风险之间存在线性关系，显示随着TMI增加SUI风险呈下降趋势（总体P < 0.001，非线性P = 0.73）。
我们的研究结果表明，ASMI与SUI风险之间无关联，而高TMI降低了SUI风险。这表明不同身体部位的肌肉量与BMI之比对SUI有不同影响。
