The risk factors for urinary incontinence in female adults with chronic cough

BACKGROUND: Female patients with chronic cough are more likely to suffer from urinary incontinence (UI). However, there are few data in regard of risks related with UI in female adults with chronic cough. METHOD: We recruited female adult patients with chronic cough from the cough specialist clinic. Demographic information and clinical characteristics including age, BMI, duration of cough, severity of cough, nature and timing of cough, cough triggers, concomitant symptoms, comorbidities and UI condition were collected. The demographics and clinical features of patients with UI and those without UI were compared. RESULT: A total of 700 female patients with the main symptom of chronic cough were included, of whom 351 (50.1%) presented with UI. As compared with patients without UI, patients with UI showed a longer mean age (years) (49.5 vs. 42.4, p < 0.001), a more severe cough symptom (median of cough Visual Analogue Scale: 65 vs. 50, p < 0.001), a higher prevalence of chronic sinusitis (17.6% vs. 8.6%, p = 0.002), and combined with a higher incidence of abdominal muscle pain due to cough (39.6% vs. 18.7%, p < 0.001).In addition, patients in UI group whose cough were more easily triggered by exercise (28.2% vs. 17.2%, p = 0.048). Multivariate logistic regression analysis indicated the above five variables were risk factors for UI in female adult patients with chronic cough. CONCLUSION: Urinary incontinence is a common complication in female patients with chronic cough. Older age, severe cough, combing with a higher proportion of chronic sinusitis and abdominal muscle pain, a cough easily triggered by exercise are identified as risk factors for urinary incontinence. We should pay more attention to female chronic coughers with these risk factors in clinics.
