Effect of nocturia on next-day sedentary activity in adults with type 2 diabetes

Purpose: Nocturia, a common cause of disturbed sleep quality and next-day fatigue, may contribute to difficulty with diabetes self-management. The purpose of this study was to examine the effect nocturia has on next-day subjectively measured mental and physical energy and objectively measured physical activity.

Methods: This secondary analysis utilized sleep diaries over one week which measured nocturia frequency and other sleep quality indicators (wake after sleep onset, sleep quality and sleep duration) along with next-day reports of mental and physical energy. Next-day physical activity was measured with the BodyMedia Sensewear armband.

Results: Sleep quality and sleep duration were associated with next-day physical and mental energy. Nocturia frequency (≥2 times per night) was associated with increased next-day sedentary activity.

Conclusion: These results suggest that nocturia could negatively affect next-day physical activity in people with diabetes.
