Abstract: | We investigated potential risk factors, including factors related to lower urinary tract symptoms (LUTS), for falls and fractures at night among outpatients and inpatients in a general hospital, via a questionnaire. The questionnaire included items to record the age, sex, number of consulting doctors, history of 11 particular medical diseases, LUTS, sleep, and falls and fractures at night. We distributed the questionnaire to 1,334 patients 51 years old or older in our hospital. Of the questionnaires completed, 96.9% were valid for analysis. Multivariate analyses revealed that "drinking water before bedtime or while in bed" was the strongest risk factor (odds ratio=7.499) for bone fractures while "postural syncope" was the strongest risk factor (odds ratio=5.041, except past medical history) for falls. In terms of LUTS, urge incontinence was a significant risk factor for falls. |
