Weak Rest-Activity Rhythms Increase Overactive Bladder Risk

A recent study published online on July 17 in *Neurourology and Urodynamics* reports a significant association between weaker rest‑activity rhythms (RARs) and unfavorable sleep profiles and a higher prevalence of overactive bladder (OAB). The research, which examined sleep patterns and urinary symptoms in a cohort of adults, found that individuals with diminished circadian regulation and poorer sleep quality were more likely to experience the urgency, frequency, and nocturia characteristic of OAB.

The investigators measured RARs using actigraphy and assessed sleep quality through validated questionnaires, then correlated these metrics with clinical OAB diagnoses. Their analysis revealed that participants with the weakest RARs and the most disrupted sleep had a markedly increased risk of OAB, independent of age, sex, and comorbid conditions. These findings suggest that sleep architecture and circadian stability may play a role in the pathophysiology of bladder dysfunction.

The study underscores the importance of evaluating sleep health in patients presenting with urinary urgency and highlights the potential for interventions targeting circadian rhythm restoration and sleep improvement to mitigate OAB symptoms. Further research is warranted to explore whether modifying sleep patterns can reduce the burden of overactive bladder in affected populations.
