Abstract:
Objective: Exploring the epidemiological state of pervasive developmental disorder in 2-6 year-old children in Beijing. Methods: A total of 21866 children aged 2-6 year-old were recruited from permanent residents of Beijing by 2-phase cluster sampling.The Clancy Autism Behavior Scale was used for screening.The Childhood Autism Rating Scale and DSM-Ⅳ were used for diagnosis.Results: 16 children were diagnosed as pervasive developmental disorder (14 with autistic disorder, 1 with atypical autistic disorder, 1 with Rett syndrome).The false negative rate was 0.80 ‰.The prevalence of pervasive developmental disorder was 0.73 ‰, the adjusted prevalence was 1.53 ‰,the average annual detective rate was 0.11‰.The prevalence rate had no difference in distribution between urban-rural, among different age groups, sex and nations(?2=0.11~1.85,P=0.739-0.173).The low family income was related to high prevalence significantly ( tendency ?2=4.70,P=0.030 ).25% children with pervasive developmental disorder had not been identified by parents or had not been to clinics.80% children with pervasive developmental disorder had not get intervention.All children had demand to get intervention. Conclusions: The prevalence of pervasive developmental disorder in 2-6 year-old children in Beijing was not low.Low family income is the risk factor.The rate of intervention was low.The government should pay close attention to the children with pervasive developmental disorder and their needs.
