Abstract
OBJECTIVE: To assess how sociodemographic and activity behaviors contribute to adolescent body mass index (BMI). METHODS: One hundred and thirteen adolescents (M = 17 years; 42% Caucasian, 56% African American) were assessed on BMI. Teens reported activity levels and caregivers reported socioeconomic status (SES). RESULTS: Adolescents from lower SES backgrounds, and from minority groups, had higher BMI (r = -.26, p < .01 and t(110) = -3.01, p < .01). Formal statistical mediation tests revealed that sedentary behaviors significantly mediated the association between SES and BMI (Z = 2.31, p < .05), whereas physical activity significantly mediated the race-BMI association (Z = 2.32, p < .05). CONCLUSIONS: Interventions targeting teen BMI could benefit by aiming to decrease sedentary behavior in low SES teens and increase physical activity in teens from minority groups.

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
