Association between physical activity intensity and nocturia risk: the mediating role of mental health.
Article in Journal of health, population, and nutrition, 2026. 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 is a prevalent condition that adversely affects overall health. Identifying modifiable lifestyle factors influencing nocturia risk is crucial. This study aimed to examine the association between physical activity intensity and nocturia risk, and to evaluate potential mediating effects of inflammation, oxidative stress, and mental health.
methodsWe conducted a cross-sectional study using data from the 2007–2018 National Health and Nutrition Examination Survey. A total of 26,686 participants aged ≥ 20 years with complete data on physical activity, nocturia, and covariates were included. Physical activity intensity was categorized as vigorous (≥ 75 min/week), moderate (≥ 150 min/week but < 75 min vigorous), or inactive. Sedentary behavior was defined as ≥ 480 min/day sitting. The primary outcome was nocturia (≥ 2 voids/night); progression was defined as ≥ 3 voids/night. Multivariable logistic regression models assessed associations. Subgroup and stratified analyses explored effect modifiers. Mediation analysis evaluated whether mental health, inflammation, and oxidative stress mediated associations.
resultsAmong 26,686 participants (49% males; 26% aged ≥ 60), both moderate- and vigorous-intensity activity were associated with lower odds of nocturia (OR: 0.893, 95% CI: 0.823–0.968; OR: 0.818, 95% CI: 0.742–0.902). For progression, ORs were 0.792 (95% CI: 0.676–0.927) and 0.818 (95% CI: 0.691–0.969), respectively. Subgroup analyses showed interactions by gender and smoking. The inverse association was significant only among non-sedentary individuals. Mental health accounted for 25% of the association, inflammation 4.8%, and oxidative stress 2.7%.
conclusionsHigher physical activity intensity is associated with lower nocturia risk. Promoting physical activity could aid in nocturia prevention and management.
