“…Pathologically, it was well established that nocturia could be caused by the decreased bladder storage capacity or increased urine output during sleep [6][7]9]. The former signifies the nocturia in younger individuals while the later predominantly occurring as nocturia polyuria (NP) in older adults as characterized by an increased proportion of the 24-hour urine output at night [7,29]. The age-related voiding frequency could be more accurately determined by the interaction between the rate of urinary output and the reservoir capacity of the low urinary tract [6], which was impossible to be detemrined in the current community-based survey conducted in streets.…”

Background: Most prevalence surveys on nocturia have focused on older populations. This study aimed to measure the nocturia prevalence across the full spectrum of male adults living in Hong Kong, where severity and associated quality-of-life (QoL) were also explored. Methods: A cross-sectional population-based survey was conducted in men aged 18 or above using the ICIQ-NQoL Questionnaire. Results: With 1,239 respondents at age ranged 18-99, the overall nocturia prevalence were found to be 63.0% (ranged 41.6-84.6% at different age groups) and 31.2% (ranged 13.0-56.3% at different age groups), for ≥1 and ≥2 bedtime voiding episodes, respectively. The chance of nocturia was dramatically increased at age 60 or above while both prevalence and voiding frequency were increased with advancing age. About 83% of the nocturia men experienced 1-2 voiding episodes per night, but many of them had self-rated their QoL poor or very poor and indicated moderate-to-high bothersome. Younger men at age 18-39 were found to have high prevalence as 41.6% and almost 30% of them rated poor or very poor QoL. Conclusions: Nocturia was not only affecting the older populations but also caused significant bothersome and negative impacts on QoL in younger males.
