Abstract
PURPOSE: Little is known about the physical activity of adolescents born prematurely. This study aimed to: 1) describe relationships between moderate to vigorous physical activity (MVPA) in adolescents born prematurely and various factors and, 2) compare their MVPA level to guidelines. METHOD: A secondary analysis was performed using data from 64 adolescents (16.1 ± 2.5 years old, born £29 weeks gestation; 57.8% girls). Time spent in MVPA was based on accelerometry data. Sociodemographic, prematurity and comorbidity variables were based on questionnaire data or, for movement difficulty, from the results of the Movement Assessment Battery for Children-Second Edition. RESULTS: Multiple regression analysis showed that participants who were older (b = -4.52, p < .001), female (b = 14.18, p = .014), with movement difficulty (b = 18.64, p = .014), with health problems (b = 11.78, p = .036) and without hyperactive behavior (trend, b = 2.04, p = .099) spent less time in MVPA. Together these variables explained 44.4% of the variance in MVPA. Most participants (79.7%) did not meet Canadian MVPA guidelines. CONCLUSION: Study results suggest that physical activity interventions should especially target adolescents born prematurely who are older, female, with health problems, and with marked movement difficulties.

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
