Risk analyses of nocturia on incident poor sleep and vice versa: the Nagahama study

Abstract

Cross-sectional relationships between nocturia and sleep problems have been well evaluated but the risk association for each incidence is scarcely reported. This analysis included 8076 participants of the Nagahama study in Japan (median age 57, 31.0% male) and associations between nocturia and self-reported, sleep-related problems (poor sleep) were evaluated cross-sectionally. Causal effects on each new-onset case were analyzed longitudinally after 5 years. Three models were applied: univariable analysis, adjustment for basic variables (i.e., demographic and lifestyle variables) and full adjustment for basic and clinical variables. The overall prevalences of poor sleep and nocturia were 18.6% and 15.5%, while poor sleep was positively associated with nocturia (OR = 1.85, p < 0.001) and vice versa (OR = 1.90, p < 0.001). Among 6579 good sleep participants, 18.5% developed poor sleep. Baseline nocturia was positively associated with this incident poor sleep (OR = 1.49, p < 0.001, full adjustment). Among 6824 non-nocturia participants, the nocturia incidence was 11.3%. Baseline poor sleep was positively associated with this incident nocturia (OR = 1.26, p = 0.026); such associations were significant only in women (OR = 1.44, p = 0.004) and under-50-year-old groups (OR = 2.82, p < 0.001), after full adjustment. Nocturia and poor sleep associate with each other. Baseline nocturia can induce new-onset poor sleep while baseline poor sleep may induce new-onset nocturia only in women.

Association between TV and/or video time and nocturia in adults: An analysis of the National Health and Nutrition Examination Survey

“…Finally, studies had shown that watching TV for an extended period had negative impacts on health, such as reducing sleep duration or affecting sleep quality 24,25 . And a decrease in sleep quality is closely linked to experiencing nocturia 26 . Additionally, a correlation has been established between watching TV and an elevated risk of obesity, a factor conclusively linked to the severity of nocturia 21,27 …”

“…24,25 And a decrease in sleep quality is closely linked to experiencing nocturia. 26 Additionally, a correlation has been established between watching TV and an elevated risk of obesity, a factor conclusively linked to the severity of nocturia. 21,27 This study has several notable strengths, such as its national representativeness and the substantial sample size obtained from NHANES data.…”
