Sleep-disordered breathing and nocturia in older adults

J Am Geriatr Soc. 2004 Jun;52(6):957-60. doi: 10.1111/j.1532-5415.2004.52264.x.


Objectives: To investigate the relationship between sleep-disordered breathing (SDB) and nocturia episodes in community-dwelling older adults.

Design: A cross-sectional study.

Setting: Community.

Participants: Community-dwelling older adults (N=72) recruited from independent living facilities and adult learning centers in Atlanta, Georgia.

Measurements: Three-day voiding diary, ambulatory sleep recording, focused physical examination, Epworth Sleepiness Scale, and Geriatric Depression Scale.

Results: Fifty-eight of the 72 subjects completed the study. The mean age+/-standard deviation was 77.7+/-6.7; 44 (76%) were female. Of the 58 subjects, 26 (45%) had an apnea-hypopnea index (AHI) of less than 10 per hour of sleep, 21 (36%) had an AHI between 10 and 24 per hour sleep, and 11 (19%) had an AHI of 25 or higher per hour of sleep. The mean nocturia episodes were 1.7+/-1.1, 1.6+/-0.9, and 2.6+/-1.4 for subjects in these groups, respectively (F=3.82; P=.028). Those with an AHI of 25 or higher had more nocturia episodes, higher mean arterial blood pressure, and higher body mass index than those with a lower AHI.

Conclusion: These results suggest that older adults with severe SDB have a greater number of nocturia episodes. These findings underscore the importance of considering SDB as a differential diagnosis in the evaluation of older patients with nocturia.
