Planetary-health literacy and mental wellbeing in Czech adolescents: insights from the HBSC survey 2022.
Article in Central European journal of public health, 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
objectivesPlanetary-health literacy (PHL), the knowledge, motivation and social support required to safeguard both human and environmental health, may help adolescents cope with climate-related distress and adopt sustainable behaviours. Evidence on the linkage between PHL and mental health from Central and Eastern Europe is lacking. The aim of the study was to describe PHL in Czech adolescents by sex, grade and family affluence, examine its association with mental-health indicators, and explore links with selected environment-relevant behaviours.
methodsCross-sectional data were drawn from the nationally representative Health Behaviour in School-aged Children (HBSC) 2022 survey (n = 4,195, 50.8% boys, ages 13 and 15 years). PHL was measured with an 11-item HBSC optional package yielding three sub-scales (knowledge, action, perceived pro-environmental social norms). Outcomes were wellbeing (WHO-5), life satisfaction (Cantril's ladder), and psychological complaints (HBSC symptom checklist). Fruit and vegetable intake plus cigarette and e-cigarette use served as behavioural correlates.
resultsGirls scored higher than boys on all PHL domains (Cohen d = 0.10-0.19). Thirteen-year-olds reported more action and stronger social norms than fifteen-year-olds (p < 0.001); socioeconomic gradients were small. In fully adjusted models, social norms were positively associated with wellbeing (β = 1.42, 95% CI: 1.12-1.72) and life satisfaction (β = 0.10, 0.08-0.13), and inversely with psychological complaints (β = -0.27, -0.33 to -0.21). Knowledge showed weak adverse relations with wellbeing and complaints, whereas action was associated with wellbeing only. Higher PHL related to daily fruit and vegetable consumption and inversely to intensive e-cigarette use; effect sizes were modest.
conclusionsPerceived pro-environmental social norms appear most tightly related to adolescent mental health, while overall PHL is slightly associated with sustainable dietary patterns and lower use of e-cigarettes. School curricula that combine climate education with collaborative, action-oriented projects may therefore deliver co-benefits for planetary and psychological health in Central and Eastern Europe.
