COVID transmission-related concerns impact on physical activity behavior: data from the iCare study.
Bibliographic record
Abstract
Objective: We explored the relationship between COVID-19 transmission-related concerns and reduced physical activity during COVID (RPAC). Methods: We analyzed data from 2,543 participants across Argentina, Brazil, Colombia, Canada, and the USA with at least 200 participants per country. The two primary concerns assessed were: a) fear of being infected, and 2) concern about personal health if infected. Participants were asked to report changes in their physical activity (PA) behavior since COVID-19 pandemic started. Results: The sample was predominantly female (75.7%), with 66.9% aged between 30-64 years. The prevalence of participants who reported RPAC remained stable in South American countries but increased in Canada (+7.8 percentage points [p.p.]; p = 0.001) and decreased in the USA (-9.7 pp; p = 0.003). Concerns about personal health were significantly associated with RPAC in South America (PR = 1.47; 95% CI: 1.09; 1.97), while no association was found in North America. Notably, participants from Colombia (PR = 1.90; 95% CI: 1.09; 3.31), and the USA (PR = 1.48; 95% CI: 1.01; 2.17) were more likely to report RPAC due to COVID-19 concerns. Conclusion: While participants reduced their PA behavior in South American countries and Canada during the first 15 months of the pandemic, COVID 19-related concerns stayed high. In contrast in the USA less participants reported RPAC, as concerns decreased, suggesting a shift in PA behavior as COVID-19-related concerns lessened.

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.
