| Research Abstract |
We evaluated the association of nocturia with fracture and death in a large, community based sample of Japanese individuals 70 years old or older. We compared the risk of bone fracture and death with or without nocturia in a multivariate Cox proportional hazard model. For all fractures with nocturia the HR was 2. 01 (95%CI 1. 04-3. 87). The mortality rate in individuals with nocturia was significantly higher than in those without nocturia. For mortality in patients with nocturia \adjusted HR was 1. 98 (95%CI 1. 09-3. 59, p=0. 03). During a 5-year observation period elderly individuals with nocturia were at greater risk for fracture and death than those without nocturia.
