Nocturia: A Risk Factor for Falls in the Elderly

TLDR

To assess whether nocturia predicts falls and fractures in older adults, this study examined its association with reported falls and bone fractures. A cross‑sectional analysis of 1,508 ambulatory seniors (988 women, 520 men) from a longitudinal health screening program compared falls and fractures between those with and without nocturia. Participants reporting nocturia twice or more had 1.84‑fold higher odds of falls, rising to 2.15 with >3 events, yet fracture rates were unchanged, indicating nocturia is a significant fall risk factor.

Abstract

Objective : To determine if nocturia is a risk factor for reported falls and bone fractures in older persons. Objective : Cross‐sectional study comparing falls in men and women with and without nocturia. Setting : Longitudinal health screening program of ambulatory elderly participants. Participants : Participants included 988 (65.5%) women and 520 (34.5%) men who had completed their tenth annual visit to the program. Main Outcome Measures : Reported falls in the past year and reported bone fractures in the past 5 years. Results : Participants who reported nocturia at least twice during the night were at significantly greater risk to report falls (Odds Ratio = 1.84; 95% CI = 1.05–3.22), and the risk increased in subjects reporting more than three nocturia events (Odds Ratio = 2.15; 95% CI = 1.04–4.44). The significant increase in falls reported by nocturia participants did not result in an increase in reported bone fractures in the past 5 years ( P < 0.4360). Conclusions : Nocturia is an important risk factor for falls in ambulatory elderly persons. Preventive measures should be taken to decrease nocturia events and to decrease the risk of falling during these nocturia events. J Am Geriatr Soc 40:1217–1220, 1992
