根据这份报告，自闭症谱系障碍 (ASD) 的特点是社交互动和沟通障碍，以及受限、重复和刻板的行为模式，症状通常在三岁之前显现出来。这些疾病的复杂性，加上缺乏用于诊断的生物标志物以及临床定义随时间的变化，给监测自闭症谱系障碍的患病率带来了挑战。准确报告数据对于了解人群中自闭症谱系障碍的患病率至关重要，并有助于指导研究。自闭症和发育障碍监测 (ADDM) 网络是一个主动监测系统，用于估计 ASD 的患病率，并描述父母或监护人居住在美国 14 个 ADDM 站点的 8 岁儿童的其他特征。本报告重点关注 2008 年 ASD 的流行情况。
According to this report, autism spectrum disorders (ASDs) are characterised by impairments in social interaction and communication and by restricted, repetitive, and stereotyped patterns of behaviour and symptoms are typically apparent before the age of three. The complex nature of these disorders, coupled with a lack of biologic markers for diagnosis and changes in clinical definitions over time, creates challenges in monitoring the prevalence of ASDs. Accurate reporting of data is essential to understand the prevalence of ASDs in the population and can help direct research. The Autism and Developmental Disabilities Monitoring (ADDM) Network is an active surveillance system that estimates the prevalence of ASDs and describes other characteristics among children aged 8 years whose parents or guardians reside within 14 ADDM sites in the United States. This report focuses on the prevalence of ASDs in 2008.
