Miyauchi Y, Okazoe H, Tamaki M, et al. - Researchers determined how age influences the link between obstructive sleep apnea syndrome (OSAS), nocturia, and other lower urinary tract symptoms, via this secondary analysis using data from a previously done prospective observational cohort study on OSAS and nocturia. Overall 90 people suspected of having OSAS were analyzed. Young patients and elderly patients aged < 65 years and ≥ 65 years, respectively. A significant link of night-time frequency with nocturnal urine volume, apnea-hypopnea index score, and total International Prostate Symptom Score, was revealed in young patients. However, no link of night-time frequency with demographic and polysomnographic features was evident in elderly participants. In order to compare the severity of OSAS, night-time frequency as well as urinary sodium content significantly raised solely in young patients. Experts concluded OSAS as a strong candidate of causative factor for nocturia among younger people. They recommended considering OSAS as a potential cause of nocturia in cases where younger patients complain nocturia without any urological disorders.
