Physical Activity Moderates the Relationship Between Screen Time and Body Dissatisfaction in Early Adulthood
Bibliographic record
Abstract
The transition to adulthood is a vulnerable period for the development of body image issues, which can increase the risk of behavioral disorders such as body dysmorphic and eating disorders. This study explored whether adherence to physical activity guidelines moderates the association between recreational screen time and body dissatisfaction in early adulthood. A sample of 1,475 young adults (mean age 18.81 years, 60.9% female) from 17 French-speaking public colleges in Quebec, Canada, completed self-report questionnaires in Fall 2021 and Winter 2022. Participants reported their daily recreational screen time, engagement in physical activity over the past 3 months, and sociodemographic characteristics. The analysis, based on multivariate linear regression, showed that higher screen time was associated with greater body dissatisfaction, but this relationship was weaker among participants who met the World Health Organization's physical activity guidelines. These findings suggest that adherence to physical activity guidelines may buffer the negative effects of recreational screen time on body dissatisfaction in young adults, highlighting the value of promoting physical activity in interventions aimed at reducing body dissatisfaction.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
