The association between pelvic girdle pain and urinary incontinence among pregnant women in the second trimester

摘要

Objective: To examine the association among pelvic girdle pain (PGP), urinary incontinence (UI), and pelvic floor muscle (PFM) function in pregnant women in the second trimester. Methods: Fifty-five pregnant women (29 with PGP and 26 without) were enrolled. Urinary incontinence was measured via the International Consultation on Incontinence Questionnaire-Short Form. Vaginal examination assessed PFM contract-relax patterns and muscle strength. Results: Overall, 51 women (26 with PGP and 25 without) were included in the final analyses. After controlling for PFM muscle strength, women with PGP were significantly more likely to have UI (P = 0.03). After controlling for pain status, having little or no PFM contraction was significantly associated with UI (P = 0.03). There was no association between PGP and PFM weakness. Conclusion: There was an association between PGP and UI and between UI and PFM weakness among the study participants. Lack of PFM weakness in women with PGP during pregnancy may reflect acuity of pain or measurement error.
