The prevalence, associated factors, and impact of urinary incontinence in pregnant and postpartum women in Nanjing, China: A cross-sectional study

OBJECTIVE: Urinary incontinence (UI) is highly prevalent in antenatal and postnatal women while the prevalence of UI varied largely from 3.84% to 38.65%. This study was to assess the prevalence of UI, the associated factors, and the impact of UI on daily life in pregnant and postpartum women in Nanjing, China. METHODS: The prevalence of UI and the impact of UI on life were assessed by the validated Chinese version of International Consultation on Incontinence Questionnaire-urinary incontinence-short form and the validated Chinese version of urinary incontinence quality of life. The associated factors were estimated by using logistic regression analysis. RESULTS: UI affected 37.80% of pregnant women and 16.41% of postpartum women of the study population. Among the pregnant participants, the prevalence rates of stress UI, urge UI, and mixed UI were 25.77%, 4.47%, and 7.10%, respectively. Among the postpartum women, the prevalence rates of stress UI, urge UI, and mixed UI were 11.15%, 1.92%, and 2.69%, respectively. In both pregnant women and postpartum women, vaginal delivery had significantly increased the odds of reporting UI (p=0.007, p=0.003, respectively). The impact of UI on daily life was significantly greater in postpartum women compared to pregnant women especially in social embarrassment (p=0.000). CONCLUSION: The prevalence rates of UI were high in pregnant women in Nanjing, China. Vaginal delivery significantly increased odds of reporting UI. UI has a great impact on pregnant and postpartum women's life, especially in social embarrassment.
