Sleep in Farm Adolescents
Bibliographic record
Abstract
PURPOSE: The objectives were to: (1) describe sleep timing and patterns among adolescents who live or work on farms; (2) compare these sleep characteristics to those of nonfarm adolescents; (3) explore whether the above sleep and farm versus nonfarm differences varied by age and gender. METHODS: Participants were aged 11-16 years and were abstracted from the 2014 Canadian Health Behaviour in School-aged Children study. Records from 2,160 farm adolescents were frequency matched (by school, gender, and grade) to records from 2,210 nonfarm adolescents. Participants self-reported their bedtimes and wake-up times on weekdays and weekends. FINDINGS: Among farm adolescents, average nightly sleep duration (hours:minutes) ranged from 08:34 among 14- to 16-year-old girls to 09:21 among 11- to 13-year-old girls. Approximately 24% to 32% of farm adolescents did not meet minimal sleep duration targets. For 11- to 13-year-olds, sleep characteristics did not differ according to farm status. However, for 14- to 16-year-olds, farm adolescents had shorter sleep durations than nonfarm adolescents (23 minutes for boys, P = .02; 20 minutes for girls, P = .06). Furthermore, a greater proportion of 14- to 16-year-old farm boys had sleep duration values less than the recommended 8 hours/night (27.7% vs 19.6%, P = .05). CONCLUSIONS: This study profiles the sleep experiences of 11- to 16-year-old farm adolescents. Almost 1 in 3 of these adolescents did not get adequate sleep. Older adolescents who lived or worked on a farm slept less than comparably aged nonfarm adolescents. This may reflect their participation in morning chores essential to the farm operation and may increase their injury risk.

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.
