Abstract

Nocturia and depression commonly coexist and may share underlying pathways. We examined the cross-sectional association between nocturia frequency and clinically relevant depressive symptoms.
We analyzed 4,162 adults from the National Health and Nutrition Examination Survey (NHANES) 2021-2023. Nocturia was categorized as 0, 1, 2, or ≥3 voids/night; a Patient Health Questionnaire-9 (PHQ-9) score ≥10 defined clinically relevant depressive symptoms. Survey-weighted logistic regression, an ordinal trend test, and subgroup analyses were conducted. A Chinese cohort (n = 255) was used for exploratory sleep-pathway analyses. A sensitivity analysis used a modified Pittsburgh Sleep Quality Index (PSQI) score excluding the sleep-disturbance component, which includes the nocturnal bathroom-use item.
In the fully adjusted complex survey model, two voids/night (OR: 1.42; 95% CI: 1.05-1.92; p = 0.026) and ≥3 voids/night (OR: 1.83; 95% CI: 1.40-2.40; p < 0.001) were associated with higher odds of clinically relevant depressive symptoms, with an ordinal trend (p < 0.001). An exploratory age interaction was observed (Wald p for interaction = 0.043). In the Chinese exploratory cohort, the unstandardized indirect effect through total PSQI score was 0.244 (bootstrap 95% CI 0.094-0.426), whereas the total and direct effects were non-significant. A sensitivity analysis excluding the PSQI sleep-disturbance component yielded a smaller but still positive indirect effect (0.181; bootstrap 95% CI 0.053-0.342).
Frequent nocturia was cross-sectionally associated with clinically relevant depressive symptoms. The Chinese exploratory outpatient cohort provided exploratory support for a sleep-related statistical pathway, which was attenuated but remained positive after excluding the PSQI sleep-disturbance component. These findings highlight nocturia as a clinically relevant symptom linking urinary, sleep, and mental health, while longitudinal studies are needed to clarify temporal and causal relationships.
