Abstract
The obesity epidemic in North America has focused attention on the health risks of excess weight gain. The transition from high school to university is a critical period for weight gain, commonly referred to as the Freshman 15. The purpose of this study was to investigate the effect of the transition from high school to university on anthropometrics and physical and sedentary activities in males. A total of 108 males completed 3 study visits: the summer prior to first year university, and the ends of the first and second semesters. Outcome measures were body mass, height, body mass index (BMI), body fat, waist circumference, hip circumference, waist:hip ratio, dietary intake, and participation in physical and sedentary activities. Between the summer prior to and the end of first year university, male students experienced a significant weight gain, of 3.0 kg, with significant increases in BMI, body fat, waist circumference, hip circumference, and waist:hip ratio. Energy and nutrient intake did not change. Final body mass was significantly predicted by intention for body mass to stay the same, relative to weight loss intention. Fast aerobic physical activity significantly decreased between the summer prior to and the end of first year university, while slow aerobic physical activity, strength training, and flexibility training did not change. Computer and studying time significantly increased, while television time and hours of nightly sleep significantly decreased between the summer prior to and the end of first year university. Weekly alcoholic drinks and binge drinking frequency significantly increased over this time period. In conclusion, between the summer prior to and the end of first year university, male students gained an average of 3.0 kg, with increases in related anthropometrics. These changes may be due to body mass change intention and (or) the observed decreased physical and increased sedentary activities, but appear to be unrelated to dietary intake.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
