There is a growing need to improve health management strategies for the middle-aged generation to ensure their health in future. The aim of this study was to identify specific risk factors for urinary incontinence (UI) in middle-aged women. In 2014, we randomly selected 800 women between 50 and 64 years from the officially-registered resident database of City A in Japan. Each selected individual was sent a self-administered questionnaire targeting 28 factors, including fundamental attributes, health condition, medical history, present illness, exercise habits, and activities. Participants also received the International Consultation on Incontinence Questionnaire-Short Form (ICIQ - SF). Self-reported UI was defined as frequent UI occurring at least once a week. In total, we analyzed the responses of 173 women. Within this cohort, the self-reported prevalence of UI was 34.1%. There were statistically significant associations of UI with walking time and body weight. Our future studies will aim to conduct a follow-up survey to further clarify the risk factors of UI in middle-aged women.
