Toujours laissés pour compte : les jeunes noirs d'âge scolaire reçoivent moins souvent un diagnostic de TSA par rapport aux jeunes blancs

Aperçu: G.M.

Des recherches antérieures suggèrent que les enfants noirs sont à risque de retards dans le diagnostic de l'autisme, mais les facteurs qui influencent le moment du diagnostic entre les groupes ethniques restent flous. 

Cette étude a analysé les données d'enfants noirs et blancs qui ont reçu un premier diagnostic d'autisme dans une clinique spécialisée. Les jeunes noirs étaient sous-représentés dans le groupe qui a reçu un premier diagnostic au milieu/à la fin de l'enfance (c'est-à-dire après l'âge de six ans). Recevoir un diagnostic plus tard dans l'enfance était lié à un QI plus élevé (niveau de tendance) et à plus de problèmes d'intériorisation pour les enfants blancs alors qu'il était lié à un QI plus faible (niveau de tendance) et à une intensité plus élevée des symptômes de TSA pour les enfants noirs. 

Les résultats suggèrent que les disparités ethniques dans l'identification précoce de l'autisme peuvent diminuer mais persistent chez les personnes diagnostiquées plus tard dans l'enfance.

Still Left Behind: Fewer Black School-Aged Youth Receive ASD Diagnoses Compared to White Youth

Affiliations

Abstract

Prior research suggests that Black children are at risk for delays in diagnosis of autism, but factors that influence diagnostic timing across races remain unclear. This study analyzed data from Black and White children who received a first-time autism diagnosis at a specialty clinic. Black youth were under-represented in the group who received a first diagnosis in middle/late childhood (i.e., after age six). Receiving a diagnosis later in childhood was related to higher IQ (trend level) and more internalizing problems for White children whereas it was related to lower IQ (trend level) and higher ASD symptom intensity for Black children. Findings suggest racial disparities in early identification of autism may be diminishing but persist among those diagnosed later in childhood..
