The pathogenesis of vaginal wind remains unclear. This study was aimed at assessing the association between functional constipation and vaginal wind in women at 6 weeks postpartum.
This is a multicenter cross-sectional study. We collected data, such as baseline demographic, clinical characteristics, pelvic organ prolapse quantification score. and surface electromyography parameters of pelvic floor muscles, of women at 6 weeks postpartum who visited the postpartum rehabilitation clinic between May 2022 and September 2022. The cohort data were from women who visited the postpartum rehabilitation clinic of the First Affiliated Hospital of Gannan Medical University and the Women and Children's Health Care Hospital of Yudu County. Follow-up for the control and study cohorts was conducted until 6 weeks postpartum.
Among the 377 women, 101 (26.79%) reported vaginal wind. Multivariate regression analysis showed that postpartum women with functional constipation were at a higher risk for vaginal wind than women without functional constipation (odds ratio [OR], 2.41). The results remained stable across the propensity score analyses (OR, 1.86-2.30). In addition, we found age, body mass index, mode of delivery, changes in the anatomical location of Bp points, urinary incontinence, pelvic floor muscle strength, and birth weight of the neonate were not associated with increased odds of vaginal wind in women at 6 weeks postpartum.
Vaginal wind is common among women at 6 weeks postpartum and is associated with functional constipation. Functional constipation may serve as a reference for the pathogenesis, prevention, and treatment of vaginal wind.
阴吹的发病机制尚不清楚。本研究旨在评估产后6周女性功能性便秘与阴吹之间的关联。
这是一项多中心横断面研究。我们收集了2022年5月至2022年9月期间到产后康复门诊就诊的产后6周女性的基线人口统计学、临床特征、盆腔器官脱垂定量评分以及盆底肌肉表面肌电图参数等数据。队列数据来自赣南医学院第一附属医院和于都县妇幼保健院产后康复门诊的女性。对对照组和研究队列进行随访直至产后6周。
在377名女性中，101名（26.79%）报告有阴吹。多因素回归分析显示，有功能性便秘的产后女性发生阴吹的风险高于无功能性便秘的女性（比值比[OR]，2.41）。在倾向得分分析中结果保持稳定（OR，1.86 - 2.30）。此外，我们发现年龄、体重指数、分娩方式、Bp点解剖位置变化、尿失禁、盆底肌肉力量和新生儿出生体重与产后6周女性阴吹几率增加无关。
阴吹在产后6周女性中很常见，且与功能性便秘有关。功能性便秘可能为阴吹的发病机制、预防和治疗提供参考。
