Abstract
Promoting outdoor play and participation in sports and organized physical activities in children may depend on neighborhood characteristics. This study investigated associations between neighborhood streets and physical activities among Mexican children ( N = 1,509, 6-11 years). Child sociodemographic characteristics and physical activity were measured in schools in Guadalajara ( n = 10), Mexico City ( n = 13), and Puerto Vallarta ( n = 3), Mexico, in 2012. Street segments within an 800 m radius around each school were measured using the Pedestrian Environment Data Scan. Most (75.8%) played outdoors; 47.4% participated in sports and 40% in organized physical activities. Fewer path obstructions and more pedestrian amenities were associated positively with outdoor play. Greater street cleanliness, more pedestrian amenities, and more path obstructions were associated with less participation in sports or organized activities. Walkability was negatively associated with all physical activities. Fostering safe and appealing streets may help promote outdoor play time, but not sports participation, for Mexican children.

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 it
