Maternal HIV status and motor milestone acquisition among Ghanaian infants
Bibliographic record
Abstract
As part of the RIING project (Research to Improve Infant Nutrition and Growth) we examined infants' motor milestone (MM) acquisition in relation to Ghanaian mothers' HIV status. Mothers' prenatally diagnosed as HIV positive (n=104), HIV negative (n=132) and HIV status unknown (n=129) were followed up twice weekly at home for MM assessment from 4 to 12 months. At each home visit the following were assessed: i) sitting without support, ii) hands and knees crawling, iii) standing with assistance, iv) walking with assistance, v) standing alone, and vi) walking alone. The mean age (days) for MM achievement was not significantly different among children of the three groups of mothers (all groups combined: sitting without support 170.7± 24.5 d, hands and knees crawling 243.0± 34.9 d, standing with assistance 261.0± 38.9 d, walking with assistance 295.3± 46.8 d, standing alone 329.0± 36.7 d, and walking alone 350.3± 35.1 d) However, by 12 months 15.4 % of the HIV positive, 31.8% of the HIV negative, and 10.1% of the HIV unknown mothers' children were walking alone (p<0.05). The results suggest possible influence of maternal HIV status on child MM acquisition. Funded by NIH Grant HD436020

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.
