Physical exercise and loneliness in higher education: a national study of Norwegian students.
Article in BMC psychology, 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
backgroundPhysical activity has been associated with lower levels of loneliness. However, limited research has explored whether exercise frequency, intensity, and duration are associated with loneliness. The aim of this study was to investigate the associations between exercise frequency, intensity, and duration, and loneliness among Norwegian college and university students.
methodsData from the National Student Health and Well-being Survey in Norway (SHoT 2022), including 59,544 full-time students aged 18–35 years, were analyzed. The Three-Item Loneliness Scale was used to measure three dimensions of loneliness: lack of companionship, feeling left out, and feeling isolated. Self-reported physical exercise was categorized by frequency, intensity, and duration. Logistic regression was applied to examine the association between physical exercise and loneliness, adjusting for sociodemographic (age, relationship status, and parents’ educational level) and behavioral (sleep duration, smoking, snus [smokeless tobacco], and alcohol consumption) factors.
resultsPhysical exercise was inversely associated with loneliness across all dimensions. The strongest associations were observed between exercise frequency and feeling isolated. In sex-stratified analyses, associations were generally stronger in males than in females for higher exercise frequency and longer duration. Specifically, in adjusted models, females exercising 4 to 5 times per week had lower odds of feeling isolated than non-exercisers (OR 0.43), whereas males exercising almost daily also had lower odds of feeling isolated (OR 0.47). Moderate-intensity exercise was associated with lower loneliness levels for both sexes (ORs 0.65–0.76), compared with low-intensity exercise.
conclusionRegular physical exercise was associated with lower levels of loneliness among college and university students. Higher exercise frequency and longer duration showed stronger associations among males than females. Sex-specific, longitudinal, and experimental studies are needed to identify causal relationships and explore underlying mechanisms.
