| Abstract: |
Background We randomly sampled a healthy community to evaluate the prevalence and associated risk factors of urinary incontinence.
Methods The survey was performed in Fuzhou, China. Of women over twenty years of age in the city, 3.0% were randomly selected and 4684 evaluated by Bristol Female Urinary Tract Symptoms Questionnaire.
Results Of the women in Fuzhou, 19.0% had urinary incontinence. The prevalence of stress incontinence, urge incontinence and mixed incontinence was 16.6% (n=777), 10.0% (n=468), 7.7% (n=360) respectively. The prevalence of the three types of urinary incontinence increased significantly with age (P<0.01). In multiple logistic models, age (OR, 1.3, 95%CI, 1.1－1.4), vaginal delivery (3.0, 1.9－4.7), parity >2 (2.1, 1.5－2.9), hypertension (2.7, 1.4－5.6), constipation (2.6, 1.8－3.8), alcohol consumption (4.7, 1.1－20.2), episiotomy (1.7, 1.4－2.0), higher body mass index (BMI, 1.8, 1.5－2.2) and unskilled worker (0.7, 0.5－0.8) were potential risk factors for stress incontinence. Urge incontinence was associated with age (OR, 1.3, 95%CI, 0.9－1.3), menopause (1.6, 1.1－2.4), Caesarean delivery (0.2, 0.1－0.5), parity >2 (2.6, 1.8－3.8), constipation (2.3, 1.4－3.7), foetal birthweight (1.7, 1.1－2.4), episiotomy (1.4, 1.1－1.8), higher BMI (1.5, 1.2－2.0) and unskilled worker (0.7, 0.5－0.9).
Conclusions The prevalence of urinary incontinence and its subtypes in Chinese women is lower than that of occidental women. In China, age, vaginal delivery, parity, hypertension, constipation, alcohol consumption, episiotomy, higher BMI are potential risk factors for stress incontinence. Urge incontinence is associated with age, menopause, Caesarean delivery, parity, constipation, foetal birthweight, episiotomy, higher body mass index.

Urinary incontinence (UI) and associated lower urinary tract symptoms are widespread and troubling conditions affecting 11% to 57% of the adult women and it can severely compromise their social life.［1,2］ Urinary incontinence is defined by the International Continence Society as “the complaint of involuntary leakage of urine”.［3］ Urinary incontinence is increasingly recognized as a health and economic problem, which affects the physical, psychological, social and economic wellbeing of individuals and their families and poses a substantial economic burden on health and social services.［4,5］ The trend in studying urinary incontinence is to place more emphasis on primary health care, because prevention is much less costly than cure.［6］ Understanding the prevalence, the natural history and the risk factors of urinary incontinence may help direct treatment resources and provide preventive steps in the future.
