Association between nocturia and sleep issues, incorporating the impact of lifestyle habits perceived as promoting sleep in an internet survey.

A mutual relationship between nocturia and sleep disturbances is assumed; however, evidence for these associations in the general population remains limited, particularly regarding sleep-promoting lifestyle habits. This cross-sectional internet study examined associations between nocturia, sleep issues, and lifestyle habits perceived as promoting sleep in 3,317 participants in July 2019. The prevalence of nocturia increased with age, while overall sleep satisfaction tended to improve with age. However, individuals with more frequent nocturnal voids reported lower sleep satisfaction. Sleep dissatisfaction was significantly correlated with nocturnal urinary frequency in both men (r = 0.16) and women (r = 0.18, p < 0.001), emphasizing the impact of nocturia on sleep quality. Furthermore, it revealed that nocturia was associated with various sleep issues. In men, mid-wakefulness (OR = 3.32, p < 0.001) and difficulty falling asleep (OR = 1.37, p < 0.050) were key factors, whereas in women, mid-wakefulness (OR = 11.2, p < 0.001) and shallow sleep (OR = 1.77, p = 0.010) were significant. Notably, it was found that lifestyle habits, such as drinking tea or alcohol, which can exacerbate nocturia and reduce sleep quality, are undertaken with intention of promoting good sleep. Conversely, good bedding (OR = 0.75, p = 0.010) was associated with fewer nocturnal voids. These findings highlight the complex interplay between nocturia, sleep issues, and lifestyle behaviors, providing valuable insights for addressing these interconnected issues.
