Objective: The objective of this study was to investigate the association between chronic back pain (CBP) and urinary incontinence (UI) in women.
Study Design: This study was a cross-sectional, observational study.
Background: There are numerous factors associated with the development of back pain, yet little consideration has been given to the pelvic floor musculature and dysfunction of this musculature, which may also cause UI. Currently, limited research exists evaluating the relationship between back pain and UI.
Methods and Measures: Data from a sample of 2341 women from the Kentucky Women's Health Registry were used for analysis. The primary variables of interest were self-reported CBP and stress UI (SUI), with SUI serving as the primary dependent variable. Simple comparisons were performed using chi-square tests and 2-sample t tests, and multivariable associations were assessed using binary logistic regression.
Results: Reports of SUI were higher in women reporting CBP than those not reporting CBP (49.0% vs 35.2%, P < .01). After controlling for potential confounders, the adjusted SUI odds ratio for CBP versus not was 1.44 (95% confidence interval: 1.11−1.86).
Conclusion: Women who report CBP have an increased odds of having SUI. Therefore, clinicians must consider this association and the relationship of relevant trunk muscles, including pelvic floor musculature, in patients presenting with CBP and/or UI.
