Effect of School Age Sports on Leisure Time Physical Activity in Adults: The CORDIS Study
Bibliographic record
Abstract
PURPOSE: Data evaluating the impact of various types of childhood physical activity on adult leisure time physical activity (LTPA) are inconsistent. The purpose of this study was to evaluate the influence of organized childhood sporting activities on LTPA as an adult in a cohort of industrial workers. METHODS: The frequency of current LTPA, defined as a half hour or more of activity at least once per week, of 3687 industrial workers in the Cardiovascular Occupational Risk Factors in Israel Study (CORDIS) cohort was the outcome variable. We analyzed the association of organized school age sports with adult LTPA, using a multiple logistic regression model, after adjusting for sociodemographic variables including current occupational factors. RESULTS: Participating in organized school age sporting activities predicted LTPA as an adult [adjusted odds ratio (OR) 3.55, 95% confidence intervals (95% CI) 2.97-4.23]. This association was consistent in the various subgroups of marital status, age, smoking, shift work, body mass index, and religious observance. CONCLUSIONS: Organized school age sporting activities influenced future LTPA in this cohort. Attempts to promote these activities may lead to increased levels of LTPA in adults.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
