Sleep duration, quality of life and depression in adolescents: a school-based survey
Bibliographic record
Abstract
BACKGROUND: The main objective of this study was to assess the link between sleep duration, quality of life and depression in adolescents. The secondary objective was to study the sleeping behavior of a large sample of adolescents from different socioeconomic backgrounds. METHODS: Study subjects were high school students studying in or around Paris with a general, vocational or technological training background. A survey was conducted to evaluate the subject's perception of their own sleep, quality of life and depression. RESULTS: The survey analyzed 855 students between 14 and 19 years of age, with equal numbers of males and females. The average sleep duration was 7 h 14 min ±1 h 20 min and was inversely correlated with age (r=-0.142, P<0.01). Students studying vocational subjects reported significantly more sleep than students studying technological subjects (P=0.02). Univariate analyses revealed a positive relationship between sleep duration and quality of life (r=0.17, P<0.001) and an inverse relationship between sleep duration and depression (r=-0.5, P<0.001). Multivariate analyses identified depression, delayed sleep phase disorder, and medical condition as determinants of sleep duration. CONCLUSIONS: This investigation of a large student cohort has confirmed that the average sleep duration in adolescents is far below what is recommended. Depression significantly influenced sleep duration. We recommend that a quantitative and qualitative evaluation of sleep should be made during the medical examination of any adolescent.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
