Autism Spectrum Disorder (ASD) is more common than previously believed. ASD is increasingly diagnosed at very young ages. We report estimated ASD prevalence rates from a population study of 2-year-old children conducted in 2010 in Gothenburg, Sweden. Screening for ASD had been introduced at all child health centers at child age 21/2 years. All children with suspected ASD were referred for evaluation to one center, serving the whole city of Gothenburg. The prevalence for all 2-year-olds referred in 2010 and diagnosed with ASD was 0.80%. Corresponding rates for 2-year-olds referred to the center in 2000 and 2005 (when no population screening occurred) were 0.18 and 0.04%. Results suggest that early screening contributes to a large increase in diagnosed ASD cases.
自闭症谱系障碍（ASD）比以前认为的更为常见。ASD 的诊断年龄越来越小。我们报告了 2010 年在瑞典哥德堡进行的一项针对 2 岁儿童的人群研究中估计的 ASD 患病率。在儿童 21/2 岁时，所有儿童健康中心都开始进行 ASD 筛查。所有疑似 ASD 的儿童都被转介到一个中心进行评估，该中心服务于整个哥德堡市。2010 年被转介并被诊断为 ASD 的所有 2 岁儿童的患病率为 0.80%。2000 年和 2005 年（当时没有进行人群筛查）被转介到该中心的 2 岁儿童的相应比例分别为 0.18%和 0.04%。结果表明，早期筛查有助于大大增加确诊的 ASD 病例数量。
