The prevalence and risk factors of different degrees of stress urinary incontinence in Chinese women: A community-based cross-sectional study

Abstract

Aim: To investigate the prevalence of SUI and explore the factors that could influence the severity of SUI in adult females.

Design: A cross-sectional study.

Methods: A total of 1178 subjects were assessed using a risk-factor questionnaires and International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) and then divided into no SUI group, mild SUI group and moderate-to-severe SUI group according to the ICIQ-SF score. Univariate analysis between adjacent groups and ordered logistic regression models in three groups were then performed to analysis the possible associated factor with the progressive of SUI.

Results: The prevalence of SUI among adult women was 22.2% of them; 16.2% and 6% had mild SUI and moderate-to-severe SUI, respectively. Moreover, logistic analysis revealed that age, BMI, smoking, position preference for urination, urinary tract infections, urinary leaks during pregnancy, gynaecological inflammation and poor sleep quality were independent risk for the severity of SUI.

Conclusion: SUI symptoms were mostly mild among Chinese females, specific risk factors such as unhealthy living habits and urination behaviours increased the risk of SUI and the aggravation of symptoms. Therefore, targeted interventions should be formulated for women to delay disease progression.
