To evaluate the prevalence of associated risk factors of over active bladder (OAB) in people ≥40 years old in mainland of China.
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).
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 OABdry and 1.1% had OABwet . 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).
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.
评估中国大陆≥40 岁人群中膀胱过度活动症（OAB）相关危险因素的流行情况。
采用随机、基于社区的横断面研究，对中国大陆 10160 名（≥40 岁）居民进行问卷调查。现场填写膀胱过度活动症状评分（OABSS）。采用卡方检验比较不同性别、年龄组、体质指数（BMI）和有/无糖尿病（DM）患者的患病率差异。
共有 9805 名（96.5%）受试者符合最终统计分析的条件。OAB 的总体患病率为 2.1%（209/9805），其中 1.0%为 OABdry，1.1%为 OABwet。60 岁以上男性 OAB 的患病率高于女性（4.6%比 2.6%，P<0.05）。BMI≥25 的 DM 患者 OAB 的患病率明显高于无 DM 患者（P<0.05）。BMI 超过 29 的患者更可能患有 OAB（3.2%比 1.8%，P<0.05）。
在该人群中，OAB 的患病率随年龄增长而增加，且 60 岁以上男性更高。研究还表明，BMI≥25 的糖尿病患者和肥胖患者更易发生 OAB。
