美国首次对成人自闭症的研究估计有2.2%的人患有自闭症谱系障碍

The first US study of autism in adults estimates that 2.2% of Americans adults have an autism spectrum condition.

美国第一项关于成年人自闭症的研究估计，2.2%的美国成年人有自闭症谱系障碍。

That adds up to 5.4 million people age 18 and older, or about 1 in 45 people, the US Centers for Disease Control and Prevention said Monday.

美国疾病控制与预防中心(简称CDC)周一表示，18岁及以上的人有540万，约占总人口的45分之一。

This is the first CDC study to provide estimates of the number of U.S. adults with autism and fills a gap in data on adults living with autism spectrum disorder in the United States because there is no existing surveillance system to collect this information.

这是美国疾病控制与预防中心第一次提供美国成人自闭症患者的估计数字，填补了美国成人自闭症谱系障碍患者数据的空白，因为没有现有的监测系统来收集这些信息。

"This information is important because ASD is a lifelong condition, and many adults with ASD need ongoing services and supports."

“这一信息很重要，因为自闭症谱系障碍是一种终身疾病，许多患有自闭症的成年人需要持续的服务和支持。”

It's been a difficult question to answer.

这是一个很难回答的问题。

"To date, an empirical study of adult ASD prevalence in the U.S. has not been accomplished, perhaps because any single approach to ascertain adult ASD has challenges," the CDC's Patricia Dietz and colleagues wrote in their report, published in the Journal of Autism and Developmental Disorders.

美国疾病控制与预防中心的帕特里夏·迪茨及其同事在发表于《自闭症与发育障碍杂志》的报告中写道:“到目前为止，对美国成人自闭症谱系障碍患病率的实证研究尚未完成，这可能是因为任何确定成人自闭症谱系障碍的单一方法都存在挑战。”

"There are no psychometrically validated tests of ASD for adults, which leads to uncertainty for studies using tests designed for children, such as the Autism Diagnostic Observation Schedule. In addition, mixed methods are likely needed in order to reach populations living independently and in group settings."

“目前还没有针对成年人的自闭症谱系障碍的心理测量验证测试，这导致使用儿童测试的研究存在不确定性，比如自闭症诊断观察时间表。”此外，可能需要混合方法，以便接触到独立生活和群体环境中的人口。”

The CDC does regular surveys of autism in children, based on medical reports, information from parents, and schools. The most recent, in 2016. found that 1.85% of 8-year-olds were identified as having autism. That's 1 in 54 8-year-olds.

美国疾病控制与预防中心根据医学报告、来自家长和学校的信息对儿童自闭症进行定期调查。最近的一次是在2016年，发现1.85%的8岁儿童被诊断为自闭症。也就是1 / 54的8岁儿童。

For the survey of adults, the CDC team used estimates of autism among children.

在对成年人的调查中，美国疾病控制和预防中心的团队使用了儿童自闭症的估计值。

Because it's an estimate, true numbers may be above or below 2.2%, the team said.

研究小组说，因为这是一个估计值，真实数字可能高于或低于2.2%。

"The findings from this study can help states determine the need for diagnosing and providing services to adults in the United States who remain unidentified with ASD," the CDC said.

美国疾病控制与预防中心说:“这项研究的结果可以帮助各州确定诊断自闭症的必要性，并为美国仍未确诊为自闭症谱系障碍的成年人提供服务。”
