En
utilisant les données de surveillance de cinq sites participant au
Réseau de surveillance de l'autisme et des troubles du développement,
la recherche a étudié les contributions du sujet de la surveillance et des
caractéristiques sociodémographiques de la population des secteurs de
recensement sur la variation de la détermination du trouble du spectre de l'autisme et des estimations de la prévalence de 2000 à 2008 en
utilisant des modèles hiérarchiques ordinaires pour 2489 secteurs.
Les
analyses multivariantes ont montré une augmentation significative de la
détermination des cas de troubles du spectre de l'autisme à la fois par
l'école et par les services de santé.
Les résultats de l'examen des facteurs sociodémographiques des
populations du secteur ont également montré
que, après avoir contrôlé d'autres covariables, il restait une
signification statistique pour les associations entre la détermination
optimale et le pourcentage de résidents hispaniques (ratio de cotes
ajusté = 0,93, intervalle de confiance de 95% = 0,88 -0,99)
et le pourcentage de résidents ayant au moins un baccalauréat (odds
ratio ajusté = 1,06, intervalle de confiance de 95% = 1,01-1,11).
Des
facteurs sociodémographiques associés aux estimations de la prévalence
des troubles du spectre de l'autisme comprenant l'origine
ethnique, l'éducation et le revenu ont été identifiés. Il est difficile de déterminer quels facteurs spécifiques influencent les disparités, cependant, il semble que, même en présence d'éducation, les disparités ethniques sont toujours apparentes.
Ces résultats suggèrent que les disparités dans l'accès aux examens
des troubles du spectre de l'autisme et l'éducation spéciale pour le
trouble du spectre de l'autisme parmi les groupes ethniques peuvent avoir
une incidence sur la surveillance ultérieure.

Abstract
Utilizing surveillance data from five sites participating in the Autism
and Developmental Disabilities Monitoring Network, we investigated
contributions of surveillance subject and census tract population
sociodemographic characteristics on variation in autism spectrum disorder
ascertainment and prevalence estimates from 2000 to 2008 using ordinal
hierarchical models for 2489 tracts. Multivariable analyses showed a
significant increase in ascertainment of autism spectrum disorder
cases through both school and health sources, the optimal ascertainment
scenario, for cases with college-educated mothers (adjusted odds
ratio = 1.06, 95% confidence interval = 1.02-1.09).
Results from our examination of sociodemographic factors of tract populations from which cases were drawn also showed that after controlling for other covariates, statistical significance remained for associations between optimal ascertainment and percentage of Hispanic residents (adjusted odds ratio = 0.93, 95% confidence interval = 0.88-0.99) and percentage of residents with at least a bachelor's degree (adjusted odds ratio = 1.06, 95% confidence interval = 1.01-1.11). We identified sociodemographic factors associated with autism spectrum disorder prevalence estimates including race, ethnicity, education, and income. Determining which specific factors influence disparities is complicated; however, it appears that even in the presence of education, racial and ethnic disparities are still apparent. These results suggest disparities in access to autism spectrum disorder assessments and special education for autism spectrum disorder among ethnic groups may impact subsequent surveillance.
