本研究的目的是在标准化研究期间、用于定义条件的诊断代码和各国的统计分析后，比较四个国家报告的自闭症谱系障碍（ASD）、多动障碍、图雷特综合征和强迫症诊断的时间趋势。我们使用基于人群的队列，包括1990年1月1日至2007年12月31日期间丹麦、芬兰、瑞典和西澳大利亚州的所有活产儿童，并随访至2011年12月31日。主要的结果指标是每个国家向基于人口的登记系统报告的特定年龄的诊断流行率。我们观察到在丹麦、芬兰、瑞典和西澳大利亚（ASD）的出生年份队列中，所有四种疾病的年龄特异性诊断患病率增加。我们的研究结果强调了在过去20年中，与医疗保健系统接触的儿童和家庭数量的增加，这些儿童和家庭用于诊断和服务一系列儿童神经精神疾病，这种现象不仅限于ASD。此外，所研究的疾病的诊断年龄通常比已知的典型症状发作年龄高得多，我们观察到随着年龄的增加，
The objective of this study is to compare the time trend of reported diagnoses of autism spectrum disorder (ASD), hyperkinetic disorder, Tourette's syndrome, and obsessive-compulsive disorder across four countries after standardizing the study period, diagnostic codes used to define the conditions and statistical analyses across countries. We use a population-based cohort, including all live-born children in Denmark, Finland, Sweden and Western Australia, from January 1, 1990, through December 31, 2007 and followed through December 31, 2011. The main outcome measure is age-specific prevalence of diagnoses reported to population-based registry systems in each country. We observe an increase in age-specific prevalence for reported diagnoses of all four disorders across birth-year cohorts in Denmark, Finland, Sweden, and (for ASD) Western Australia. Our results highlight the increase in the last 20 years in the number of children and families in contact with health care systems for diagnosis and services for an array of childhood neuropsychiatric disorders, a phenomenon not limited to ASD. Also, the age of diagnosis of the studied disorders was often much higher than what is known of the typical age of onset of symptoms, and we observe limited leveling off in the incidence rate with increasing
