Aperçu: G.M.
Malgré le fait qu'elle comprend ~ 18% de la population mondiale, l'Inde n'a pas encore une estimation de la prévalence de l'autisme.
Cette étude a été réalisée pour estimer la prévalence de l'autisme dans une population sélectionnée d'écoliers en Inde.
L'estimation pondérée des scores SCQ supra-seuil était de 3,54% (CI: 2,88-4,3%). L'estimation
de la prévalence pondérée des scores positifs (pour le spectre
de l'autisme plus large + TSA+ autisme) était de 0,23% (0,07-0,46%). Comme
on sait que 20% des enfants dans cet état sont hors du système
scolaire, la prévalence de la TSA est susceptible d'être plus élevée
dans ce groupe, cette estimation est susceptible de représenter la
limite inférieure de la prévalence réelle.

Abstract
Despite housing ∼18% of the world's population, India does not yet have an estimate of prevalence of autism. This study was carried out to estimate the prevalence of autism
in a selected population of school-children in India. N = 11,849
children (mean age = 5.9 [SD = 1.3], 39.5% females) were selected from
various school types from three boroughs in Kolkata, India.
Parents/caregivers and teachers filled in the social and communication
disorders checklist (SCDC). Children meeting cutoff on parent-reported
SCDC were followed up with the social communication questionnaire (SCQ).
SCQ-positive children were administered the autism
diagnostic observation schedule (ADOS). Teacher report on SCDC was
available on all 11,849 children. Parent-report SCDC scores were
obtained for 5,947 children. Mean scores on teacher SCDC were
significantly lower than parent SCDC. Out of 1,247 SCDC-positive
children, 882 answered the SCQ, of whom 124 met the cutoff score of 15.
Six of these children met criteria for autism, autism spectrum disorder (ASD), or broader autism
spectrum on the ADOS. The weighted estimate of supra-threshold SCQ
scores was 3.54% (CI: 2.88-4.3%). The weighted prevalence estimate of
positive scores (for broader autism spectrum + ASD + autism)
was 0.23% (0.07-0.46%). As ∼20% children in this state are known to be
out of the school system, and ASD prevalence is likely to be higher in
this group, this estimate is likely to represent the lower-bound of the
true prevalence. This study provides preliminary data on the prevalence
of broader-spectrum autism and supra-threshold autistic traits in a population sample of school children in Eastern India. Autism Res 2017. ©2017 The Authors Autism Research published by Wiley Periodicals, Inc. on behalf of International Society for Autism Research.
