Investigate the relationship between female pelvic floor muscle (PFM) function and body composition.
Cross-sectional study-participants answered sociodemographic and urogynecological questions. The amount of fat mass was measured by dual-emission X-ray densitometry (DXA), and subcutaneous fat thickness was assessed by abdominal ultrasound. PFM assessment was performed using the Modified Oxford Scale and vaginal manometry. Descriptive analysis, independent t test, spearman correlation, and univariate regression were performed.
Ninety-nine women were included. All body composition variables evaluated, except subcutaneous fat thickness, indicated that women with a higher concentration of fat in the pelvic, android, and visceral region have lower maximum voluntary PFM contraction strength assessed by Modified Oxford Scale and manometry. The univariate model pointed out that the fat concentration increases the chances of reduced PFM strength in the entire body (0.6%), android (5.4%), visceral region (25.3%), and pelvic (89.9%). There was a correlation between the concentration of total, pelvic, and android fat with MVC/average peak.
The accumulation of "total", "pelvic", "android", and "visceral" fat mass is correlated with reduction in PFM strength, and there is an association between MVC and the variables of total and segmented fat. However, pelvic fat concentration is predictive in 89.9% of cases.
研究女性盆底肌肉（PFM）功能与身体成分之间的关系。
横断面研究——参与者回答社会人口统计学和泌尿妇科问题。通过双能X线骨密度仪（DXA）测量脂肪量，通过腹部超声评估皮下脂肪厚度。使用改良牛津量表和阴道测压法进行PFM评估。进行描述性分析、独立样本t检验、斯皮尔曼相关性分析和单变量回归分析。
纳入99名女性。除皮下脂肪厚度外，所有评估的身体成分变量均表明，盆腔、男性型和内脏区域脂肪浓度较高的女性，通过改良牛津量表和测压法评估的最大自主PFM收缩强度较低。单变量模型指出，脂肪浓度增加了全身（0.6%）、男性型（5.4%）、内脏区域（25.3%）和盆腔（89.9%）PFM强度降低的可能性。总脂肪、盆腔脂肪和男性型脂肪浓度与最大自主收缩/平均峰值之间存在相关性。
“总”、“盆腔”、“男性型”和“内脏”脂肪量的积累与PFM强度降低相关，最大自主收缩与总脂肪和分段脂肪变量之间存在关联。然而，盆腔脂肪浓度在89.9%的病例中具有预测性。
