Abstract
BACKGROUND: Epidemiological studies in adults and children have repeatedly reported an association between short sleep duration and the risk of obesity. Studies using both objective measurements of sleep and dual-energy X-ray absorptiometry in children aged three are, however, lacking. OBJECTIVE: The study aims to examine both the longitudinal and cross-sectional associations between sleep duration and adiposity indicators in children aged 3 and younger. METHODS: On a cohort of 311 infants born at term, we used parent-reported sleep duration at 9 months, 18 months and 3 years of age, and accelerometer estimated nocturnal sleep duration at 3 years of age. Sleep duration at 9 and 18 months were used to predict adiposity at 3 years of age. RESULTS: We found no associations between any of the adiposity indicators at 3 years of age and (i) parent-reported total sleep duration at 9 months, 18 months and 3 years, and (2) nocturnal sleep duration measured with accelerometry at 3 years of age. Multivariate adjustments were used in both approaches. CONCLUSION: Our results do not support the hypothesis that short sleep duration is associated with increased adiposity in this cohort of young Danish children.

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
