Associations of sedentary behavior and weekday lifestyle with mental health among Chinese senior high school students.
Article in Frontiers in 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
Background: Students in senior high school face substantial academic demands, prolonged sedentary time, constrained daily routines, and multiple imbalances in health-related behaviors. Their mental health may therefore be shaped by dietary habits, lifestyle, sedentary behavior, physical activity level, and body mass index (BMI). However, within the same school context, it remains unclear which factors-dietary habits, lifestyle habits, sedentary behavior, physical activity level, or BMI-show stronger associations with students' mental health. Methods: This cross-sectional questionnaire study was based on a school-based questionnaire survey conducted among students aged 15-17 years from a senior high school in Nanjing, China. Mental health was assessed using the World Health Organization-Five Wellbeing Index (WHO-5). Data on dietary habits, lifestyle, sedentary behavior, physical activity level, and BMI were collected. Correlation analyses and multiple linear regression analyses were performed to examine the associations between these behavioral factors and mental health. Results: Overall mental health in the sample was moderate. Sedentary time was prolonged, physical activity level was generally low, and dietary patterns were characterized by relatively regular main meals but suboptimal supplementary dietary habits. Correlation analyses showed that mental health was positively correlated with overall dietary habits ( Conclusion: Mental health in senior high school students was closely related to the structure of daily behaviors, with sedentary behavior showing the most prominent adverse association. Compared with focusing solely on increasing exercise, reducing sedentary behavior, optimizing weekday routines, and maintaining regular main meals may better align with the mental health promotion needs of the school setting.
