Aims To evaluate the prevalence of associated risk factors of over active bladder (OAB) in people ≥40 years old in mainland of China. Methods A randomized community‐based, cross‐sectional study was performed on 10,160 residents (≥40 years old) in the mainland of China using a questionnaire. The overactive bladder symptom score (OABSS) was filled upon site. The chi‐square test was used to determine the differences of prevalence between sex, age groups, body mass index (BMI) and people with and without diabetes mellitus (DM). Results A total of 9,805 (96.5%) subjects qualified for the final statistical analysis. The overall prevalence of OAB was 2.1% (209/9,805), of whom 1.0% had OAB dry and 1.1% had OAB wet . The prevalence of OAB was more common in men than in women over the age of 60 (4.6% vs. 2.6%, P < 0.05). The prevalence of OAB in subjects with DM was significantly higher than those without DM in patients with BMI ≥ 25 ( P < 0.05). The subjects with a BMI over 29 were more likely to have OAB (3.2% vs. 1.8%, P < 0.05). Conclusions In this population, the prevalence of OAB increased with age for both sexes, but was higher for males over 60 years of age. The study also showed that diabetics with BMI ≥ 25 and people suffering from obesity are more likely to have OAB. Neurourol. Urodynam. 33:387–391, 2014 . © 2013 Wiley Periodicals, Inc.
