M. L1MAETAL. Malnutrition Among Children of Adolescent Mothers in a Squatter Community of Recife, Brazil
Bibliographic record
Abstract
In a study of 357 first time mothers in a squatter community of Recife it was found that 1 in 10 were less than 15 years old and 60 per cent less than 20 at the time of their first delivery. Two groups of mothers were distinguished, viz. adolescent mothers with a mean (SD) age at first delivery of 16.7 (0.78) years and older mothers with a mean (SD) age at first delivery of 25 (0.79). More than a third were living in common-law union. Of the adolescent mothers only 58 per cent were living with the child's father. A further 23 per cent had received financial support from their own parents during the pregnancy. The rest were expelled from home. The adolescent mothers were generally worse off with a per capita income generally half of that of older mothers. About a quarter of all children studied were below the 10th centile of NCHS standards (23 per cent by weight/age; 28 per cent by height/age). The undernourished first born was 2.5 times more likely to have an adolescent mother, four times more likely to be in a household with low income, and two times more likely to have an illiterate mother as compared to the first boms who remain well nourished. The implications of these findings for urban primary health care programmes are further discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
