Associations of physical activity type and frequency with perceived stress among adolescents: a secondary analysis.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAdolescents are highly vulnerable to stress, which is closely associated with adverse psychological outcomes. Although physical activity has been linked to lower levels of perceived stress, evidence regarding how these associations vary by activity type and frequency remains limited.
methodsThe present study investigated this relationship by conducting a secondary analysis of the 2009–2024 Korea Youth Risk Behavior Survey, including 995,518 adolescents aged 12–18 years. Perceived stress was treated as the outcome (high vs. low), and physical activity was assessed as the exposure in three domains: moderate-intensity physical activity (MIPA), vigorous-intensity physical activity (VIPA), and muscle-strengthening exercise (MSE), each categorized by weekly frequency. Multivariable logistic regression models were applied, adjusting for sociodemographic and behavioral covariates.
resultsIn adjusted analyses, associations between physical activity and high perceived stress differed by activity type and weekly frequency, with the strongest inverse associations generally observed at moderate frequencies. Patterns varied across activity types and subgroups, and higher-frequency categories showed attenuated or positive associations for some activities.
conclusionsIn this nationally representative adolescent sample, perceived stress was differentially associated with the type and frequency of physical activity. These findings should be interpreted as associations rather than causal effects, as perceived stress represents one dimension of adolescent mental well-being and the data are cross-sectional. Nevertheless, the findings may inform public health initiatives and school-based programs addressing adolescent stress and well-being.
