Prevalence and risk factors of overactive bladder syndrome in Fuzhou Chinese women

Authors


Abstract

Aims

We randomly sampled a community-based, healthy population to evaluate the prevalence and associated risk factors of overactive bladder (OAB) syndrome by using the International Continence Society (ICS) definition.

Methods

We randomly sampled 6,066 women (3.0% of registered female residents aged 20 years and older in Fuzhou) and mailed Bristol Female Lower Urinary Tract Symptoms questionnaire for women self-completion. Women (4,684; 77.2%) with evaluable data were included in this study.

Results

The prevalence of OAB was 8.0% (n = 377), OABdry 2.4% (n = 114), and OABwet 5.6% (n = 263), hence 30% had OABdry and 70% OABwet. The prevalence of OAB and OABwet demonstrated an significant increasing with advancing age (P < 0.01). A multiple logistic regression analysis showed menopause, parity >2, constipation, episiotomy, and higher BMI were potential risk factors for OAB, constipation increased the occurrence of OABdry. OABwet was associated with menopause, parity >2, higher fetal birthweight, episiotomy, while cesarean delivery protected against the development of OABwet.

Conclusions

The prevalence of OAB in chinese women is lower than that of most reports in Occidental women, and increases with advancing age. Many potential risk factors increase the occurrence of OAB. Neurourol. Urodynam. 25:717–721, 2006. © 2006 Wiley-Liss, Inc.
