Maternal and child depression and stressful life events as predictors of body composition in urban Guatemalan children
Bibliographic record
Abstract
Research suggests child and maternal depression and increased stress may contribute to the etiology of obesity. This study explores psychosocial factors as predictors of body composition in 7–11 year‐old urban Guatemalan children. Results are based on baseline data from 720 children participating in a zinc supplementation study. Using WHO growth references, 22% of children were overweight or obese (Mean[SD] BMIZ = 0.32[1.1]); 30% of children and 45% of mothers exhibited high levels of depressive symptoms, with 7% of children experiencing high frequency of stress. Linear regression models show no association between child or maternal depression levels and BMIZ. Experiencing more frequent stressful life events was significantly associated with lower BMIZ (β[SE] =−0.33 [0.2]), adjusting for demographic factors and physical activity. Neither child nor maternal depression was associated with BMI, but stressful life events were negatively associated with BMI in this population. Funded by NIMH grant 5R01 MH067981‐04.

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.
