Objectives
To evaluate changes in self-reported nocturia among community dwelling adults aged 60 and older who received behavioral treatment for chronic insomnia.
Design
Secondary analysis of an RCT of a behavioral intervention for sleep.
Setting and Participants
Of the 79 enrollees in the RCT, this analysis focused on 30 who in addition to insomnia, also reported at least one nightly episode of waking up to void
Intervention
The Brief Behavioral Treatment of Insomnia (BBTI) group received instructions on reducing time in bed and setting a regular sleep schedule. The Information control (IC) group received printed materials. Both interventions were delivered by a nurse clinician.
Measurements
Self-reported nocturnal awakenings to void assessed daily for 14 days at baseline and 4 weeks post-intervention. Participants (16 IC; 14 BBTI) who reported at least one episode of nocturia per night at baseline were included in this analysis.
Results
Among individuals with nocturia at baseline, the total number of nocturnal voids over the 14-day assessment period decreased by 6.5 [sd, 4.8] in the BBTI group compared to an increase of 1.3 [sd, 7.3] in the information only control group (p=0.04, effect size 0.82). After adjusting for baseline nocturia episodes, the difference remained significant (p=.05).
Conclusion
Among older adults with concurrent insomnia and nocturia, behavioral treatment directed solely at insomnia may also improve self-reported nocturia. Behavioral treatment of insomnia should be further investigated for its effect on nocturia among individuals with concurrent insomnia and nocturia.
