Abstract
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 1239 respondents at age ranged 18–99, the overall nocturia prevalences 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 one to two 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.
Highlights
Many senior males are living with suboptimal sleep cycle and Quality of Life (QoL)that could be caused by the problem of nocturia
Study Design & Subject Recruitment. This cross-sectional study adopted a street-intercept and random walk survey design to measure the prevalence of nocturia and its health-related QoL perceived by adult males living in Hong Kong, using the Cantonese version of the ICIQ-NQoL
The present findings revealed a relatively higher age-matched prevalence for ≥1 void in younger men under 40 years old, as compared with the 35% reported in the large European Prospective Investigation into Cancer and Nutrition (EPIC) cohort study conducted in major western countries [26]
Summary
That could be caused by the problem of nocturia. The condition of nocturia is aligned with the nonrestorative sleep aspect of insomnia, as given in the full definition that “insomnia is a patient-reported problem characterized by difficulty falling asleep or difficulty maintaining sleep; i.e., frequent awakenings, difficulty returning to sleep after awakenings, or awakening too early with inability to return to sleep” [2]. Sleep quality was identified as a major mediator for several QoL domains impacted by the nocturia [5]. The association between ageing and nocturia could be at least partially explained by their comorbidity with age-related conditions ranging from urological illnesses to metabolic and neurological disorders; increasing trends have been observed in younger men [6,7,8,9]. From the sleep expertise perspective, the interplaying role of obstructive sleep apnea was proposed to explain the bidirectional mechanisms between
