Voiding Dysfunction Analysis of the Risk Factors for Overactive Bladder on the Basis of a Survey in the Community

Purpose: To evaluate the risk factors for overactive bladder (OAB) in a population aged 40 years and over in the community. Materials and Methods: We conducted a community-based survey of OAB in a pop-ulation aged 40 years and over in Guri City and Yangpyeong County, South Korea, by use of the overactive bladder symptom score (OABSS) questionnaire. A total of 926 sub-jects were included in the final analysis. The definition of OAB was more than 2 points for the urgency score and 3 points for the sum of scores. In addition, the subjects were asked about age, dwelling place, marital status, educational status, behavioral factors (smoking, drinking, etc), and medical history. Categorical variables were analyzed by using the logistic regression model and were adjusted for age by using the logistic re-gression model. Results: Overall OAB prevalence was 14.1 % (130/926), made up of 49/403 males (12.2%) and 81/523 females (15.5%). OAB prevalence increased with age (p＜0.0001). Risk fac-tors for OAB were educational status (age-adjusted p=0.0487), stroke (p=0.0414), osteo-porosis (p=0.0208), asthma (p=0.0091), rhinitis (p=0.0008), and cataract. Other factor
