Abstract
Objective: To compare low birth weight (LBW) (< 2,500g) between infants born to adolescent and adult mothers in Iquitos, Peru. Methods: A random sample of 4,467 birth records was collected. Multivariate analyses were performed to compare both the proportion of LBW and mean birth weight of newborns of adolescents (10-14 yrs, 15-19 yrs) and adults (≥ 20 yrs) and then for primiparous mothers only. Results: For all mothers, all adolescents had significantly greater odds of having a LBW infant than adults. For primiparous mothers, the same was true only for 10-14 year-olds. There were significant differences in mean birth weight between adults and both early and late adolescent age groups. Discussion: Results provide evidence for increased risk of LBW in adolescents, especially early adolescents. Further research is needed on elucidating the basis of this disparity, especially in terms of physiological and behavioural determinants.

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
