The mediating effect of sleep quality in the relationship between nocturia and psychosocial functions in nurses: a cross-sectional survey based on TARGET.
Article in BMC nursing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNocturia, the most common lower urinary tract symptom, significantly impacts individuals' physical and mental health, as well as their sleep quality. However, current research primarily focuses on the elderly, with few studies examining the professional population, particularly nurses. Given that nurses are particularly susceptible to nocturia due to frequent shift work, poor urination habits, and heavy workloads, this study aims to investigate the prevalence of nocturia among nurses and its effects on their psychosocial functions, as well as the mediating role of sleep quality.
methods105 hospitals, comprising 46,391 valid samples, were conveniently selected between February 2021 and March 2024, based on the baseline survey of the Chinese Nurses' Health Cohort Study (TARGET). Variables were measured by the International Consultation on Incontinence Questionnaire, Generalized Anxiety Disorder 7-Item Scale, Patient Health Questionnaire-9, Work-Family Balance Scale, 6-item Stanford Presenteeism Scale, and Pittsburgh Sleep Quality Index. Univariate and binomial logistic regression analyses, correlation analyses, and mediation model tests were employed.
resultsNocturia (frequency ≥ 2 times/night) was observed in 7,265 (15.7%) and poor sleep quality in 19,002 (41.0%) among nurses. Sleep quality partially mediated the relationship among nocturia-anxiety, nocturia-depression, nocturia-health-related productivity loss, and nocturia-work-family balance, with mediation effects of 1.080, 1.368, 0.538, and - 1.112, accounting for 79.70%, 78.05%, 71.68%, and 89.56% of the total effect, respectively.
conclusionsNocturia adversely affects nurses' psychosocial functions, and sleep quality mediates this relationship. Managers should focus on nurses experiencing nocturia and implement timely interventions for sleep disorders to promote mental health, enhance work-family balance, and reduce productivity loss.
