This study aimed to provide an autism spectrum disorder (ASD) prevalence update from parent and teacher report using the Longitudinal Study of Australian Children (LSAC). The LSAC is a prospective cohort study of Australian children representative of the population with two cohorts: Kinder (birth year 1999/2000) and Birth cohort (birth year 2003/2004). Children in the Birth and Kinder cohort with parent‐ and teacher‐reported ASD prevalence were compared to children without ASD. There were N = 3,381 (66%) responding in the Birth cohort at age 12 and N = 3,089 (62%) for the Kinder cohort at age 16. Quality of life was measured by the Pediatric Quality of Life Inventory, and emotional/behavior problems using the Strengths and Difficulties Questionnaire. Parent‐reported ASD prevalence increased to 4.36% [95% CI 3.56–5.19] at age 12–13 years in the Birth cohort and 2.60% [95% CI 2.07–3.31] in the Kinder cohort. Kinder cohort ASD children had more parent‐ and teacher‐reported social problems, and lower parent‐reported social and psychosocial quality of life. As expected, parent‐reported ASD prevalence continued to rise. The higher prevalence in the Birth cohort may relate to milder cases of ASD being diagnosed.

根据澳大利亚儿童的纵向研究，发现12至13岁儿童的自闭症谱系患病率。

这项研究旨在利用澳大利亚儿童纵向研究（LSAC）提供来自父母和老师报告的自闭症谱系障碍（ASD）患病率更新。LSAC是一项针对澳大利亚儿童的前瞻性队列研究，该群体代表了具有两个队列的澳大利亚儿童：金德（Kinder）（1999/2000年出生）和出生队列（2003/2004年出生）。将父母和老师报告的ASD患病率的出生和金德队列中的儿童与没有ASD的儿童进行比较。12岁时出生队列中有N = 3,381（66％），N= 16岁时的Kinder队列为3,089（62％），生活质量是通过小儿生活质量量表和“长处和困难量表”来衡量的。在出生队列中，父母报告的ASD患病率在12-13岁时增加到4.36％[95％CI 3.56-5.19]，在Kinder队列中增加了2.60％[95％CI 2.07-3.31]。金德队列ASD儿童的父母和老师报告的社会问题更多，而父母报告的社交和社会心理生活质量较低。不出所料，父母报告的ASD患病率持续上升。出生队列中较高的患病率可能与被诊断出的轻度ASD病例有关。Autism Res 2020，13：821–827。©2020国际自闭症研究协会，Wiley Periodicals，Inc.。
