PMID 27969050WHAT IT FOUND
Two or more nighttime voids were associated with more next-day sedentary time in adults with type 2 diabetes (76.4% versus 73.13% of waking time), but did not predict subjective fatigue.
Key findings
01Voiding two or more times per night was independently associated with more next-day sedentary time: 76.4% versus 73.13% of waking time.
02Perceived nightly sleep quality and sleep duration were independently associated with next-day subjective physical and mental energy.
03High and low nocturia groups did not differ significantly in daytime sleepiness, global sleep quality, A1C, BMI, or marital status.

What it does not show
The study was cross-sectional, so it cannot show that nocturia caused more sedentary time. The sample was modest and not based on a power analysis, so null findings may be false negatives. Causes of nighttime voiding, such as diuretic medications, fluid intake, glycosuria, bladder disorders, or sleep apnea severity, were not evaluated. Participants were ambulatory, could read and write English, and were screened for a CPAP trial, so results may not apply to all adults with type 2 diabetes. Nocturia, sleep quality, and energy were self-reported, while sedentary time was measured by armband.

The easy way to misread this
Do not conclude that treating nocturia will reduce sedentary time or improve diabetes control. The association is observational, the study did not test an intervention, and causes of nighttime voiding were not evaluated.
