We compared early-diagnosed autism spectrum disorder (ASD) (defined as diagnosis by age 4 years) between the 2002 and 2006 birth cohorts, in five sites of the Autism and Developmental Disabilities Monitoring Network. In the 2002 cohort, the prevalence/1000 of early-diagnosed ASD was half the 8-year-old prevalence (7.2 vs. 14.7, prevalence ratio [PR] 0.5 [0.4-0.6]). Overall, the prevalence of early-diagnosed ASD did not differ between birth cohorts (PR 1.1 [0.9-1.3]). However, in three sites with complete case ascertainment, the prevalence of early-diagnosed ASD was higher for those born in 2006 versus 2002 (PR 1.3 [1.1-1.5]), suggesting possible improvement in early identification. The lack of change in two sites may reflect less complete case ascertainment. Studies in more recent cohorts are needed.
我们在自闭症及发育障碍监测网络的五个地点，对2002年和2006年出生队列中早期诊断的自闭症谱系障碍（ASD）（定义为4岁前确诊）进行了比较。在2002年队列中，早期诊断的ASD患病率/1000是8岁患病率的一半（7.2对14.7，患病率比[PR]0.5[0.4 - 0.6]）。总体而言，出生队列之间早期诊断的ASD患病率没有差异（PR 1.1[0.9 - 1.3]）。然而，在三个病例确诊完整的地点，2006年出生者早期诊断的ASD患病率高于2002年出生者（PR 1.3[1.1 - 1.5]），这表明早期识别可能有所改善。两个地点缺乏变化可能反映了病例确诊不够完整。需要对更近的队列进行研究。
