Abstract
Human exposure to cadmium has adverse effects on the nervous system. Utilizing data from 110 age- and sex-matched case-control pairs (220 children) ages 2-8 years in Kingston, Jamaica, we compared the 75th percentile of blood cadmium concentrations in children with and without AutismSpectrum Disorder (ASD).
L'exposition humaine au cadmium a des effets nocifs sur le système nerveux. Utilisant les données d'une étude de cas témoins de 110 paires d'enfants appariés en âge et en sexe appariés (220 enfants) âgés de 2-8 ans à Kingston, en Jamaïque, nous avons comparé le 75e percentile des concentrations de cadmium dans le sang chez les enfants avec et sans troubles du spectre autistique (TSA).
In both univariable and multivariable Quantile Regression Models that controlled for potential confounding factors, we did not find any significant differences between ASD cases and typically developing (TD) controls with respect to the 75th percentile of blood cadmium concentrations, (P > 0.22). However, we found a significantly higher 75th percentile of blood cadmium concentrations in TD Jamaican children who consumed shellfish (lobsters, crabs) (P <0.05), fried plantain (P <0.01), and boiled dumpling (P <0.01).
Dans les deux modèles quantile régression univariées et multivariées de contrôle pour les facteurs de confusion potentiels, nous n'avons pas trouvé de différences significatives entre les cas avec TSA et les cas contrôle avec un développement typique (TD) par rapport au 75e centile des concentrations de cadmium dans le sang, (P> 0,22). Cependant, nous avons trouvé un 75e percentile significativement plus élevée de concentrations de cadmium dans le sang chez TD enfants jamaïcains qui ont consommé des coquillages (homards, crabes) (P <0,05), du plantain frit (P <0,01), et de la boulette bouillie (P <0,01).
We also observed that children living in Jamaica have an arithmetic mean blood cadmium concentration of 0.16μg/L which is similar to that of the children in developed countries and much lower than that of children in developing countries. Although our results do not support an association between blood cadmium concentrations and ASD, to our knowledge, this study is the first to report levels of blood cadmium in TD children as well as those with ASD in Jamaica.
Bien que nos résultats ne soutiennent pas une association entre les concentrations de cadmium dans le sang et les TSA, à notre connaissance, cette étude est la première à rapporter des niveaux de cadmium dans le sang des enfants TD, ainsi que ceux atteints de TSA en Jamaïque.
