Abstract

fetched live from OpenAlex

Les niveaux sériques de vitamine D des minorités visibles sont inférieures à celui des Blancs, mais n'a pas été étudié auprès des enfants moins de 6 ans.Donc, l'objective de cette étude était d'estimer la prévalence d'insuffisance en vitamine D et d'identifier les paramètres explicatifs pour 502 enfants (2 à 5 ans) fréquentant les garderies de Montréal entre Juin 2010 et 2011.La concentration sérique capillaire de 25-hydroxy vitamine D (25(OH)D) était ≤ 50 nmol/L dans 10% des enfants Blancs (n = 262), 14% des Noirs (n = 36), 0% des Latino-Américains (n = 15) , 16% des Arabes (n = 45), 9% des Asiatiques (n = 43) and 14% des Mélangés (n = 101).Le paramètre explicatif principale était l'exposition au soleil pour les enfants Blancs (r 2 = 0.0.09,P = 0.263), l'apport de supplément en vitamine D pour les Arabes (r 2 = 0.18, P < 0.001) et Mélangés (r 2 = 0.16, P < 0.001), le revenu familiale pour les Noirs (r 2 = 0.28, P = 0.009) et le type de peau pour les Asiatiques (r 2 = 0.18, P<0.001).Plus de 80% des enfants des garderies avaient des taux adéquats de vitamine D peu importe l'ethnicité, le statut d'immigration, le nombre d'année de résidence au Canada ou le statut socioéconomique.Puisque les paramètres explicatifs du statut de vitamine D étaient différents pour chaque ethnicité, les stratégies pour améliorer le statut de vitamine D pour ceux qui présentent de faibles taux devront considérer les besoins unique de chaque groupe ethnique.

Not 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.
