Abstract
PURPOSE: To examine associations of neighborhood walkability and recreation environment variables with physical activity in adolescents. METHODS: The cross-sectional study was conducted with 98 white or Mexican-American adolescents (mean age = 16.2 years). Physical activity was measured with 7 days of accelerometer monitoring. Height and weight were measured to compute body mass index (BMI). Environmental measures were created using geographic information systems. A neighborhood walkability index was based on land use mix, retail density, street connectivity, and residential density. Proximity to public and private recreation facilities was assessed. RESULTS: In a linear regression, the walkability index within 0.5 mile of homes was related to minutes of moderate to vigorous physical activity, explaining approximately 4% of variance. Recreation variables were not related to physical activity, and BMI was not explained by environmental variables. CONCLUSION: Neighborhood walkability was related to adolescents'physical activity, similar to findings for adults.

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
