Does Race or Sex Moderate the Perceived Built Environment/Physical Activity Relationship in College Students?
Bibliographic record
Abstract
The purpose of this research was to explore the relationship between the perceived built environment and physical activity (PA) among college students, and to determine whether race and/or sex moderate this relationship. Participants were 785 college students (435 students in Study 1 and 350 in Study 2). Students completed questionnaires assessing characteristics of their neighborhood, and were followed up 1 (Study 1) or 2 (Study 2) weeks later to measure PA levels. Seeing others in one's neighbourhood being active was found to be significantly related (p<.01) to higher levels of PA for students in both studies. In Study 2, race was found to moderate the relationship between having many places within walking distance and PA, affecting African Americans more strongly than Caucasians. Sex was not found to moderate the perceived built environment/PA relationship. It appears that certain aspects of the perceived built environment may have an effect on the level of PA in college students, with race moderating this relationship.

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.
