美國首次對成人自閉癥的研究估計有2.2%的人患有自閉癥譜系障礙

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

美國第一項關于成年人自閉癥的研究估計，2.2%的美國成年人有自閉癥譜系障礙。

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.

美國疾病控制與預防中心(簡稱CDC)周一表示，18歲及以上的人有540萬，約占總人口的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.

這是美國疾病控制與預防中心第一次提供美國成人自閉癥患者的估計數(shù)字，填補了美國成人自閉癥譜系障礙患者數(shù)據(jù)的空白，因為沒有現(xiàn)有的監(jiān)測系統(tǒng)來收集這些信息。

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

“這一信息很重要，因為自閉癥譜系障礙是一種終身疾病，許多患有自閉癥的成年人需要持續(xù)的服務和支持。”

It's been a difficult question to answer.

這是一個很難回答的問題。

"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.

美國疾病控制與預防中心的帕特里夏·迪茨及其同事在發(fā)表于《自閉癥與發(fā)育障礙雜志》的報告中寫道:“到目前為止，對美國成人自閉癥譜系障礙患病率的實證研究尚未完成，這可能是因為任何確定成人自閉癥譜系障礙的單一方法都存在挑戰(zhàn)。”

"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."

“目前還沒有針對成年人的自閉癥譜系障礙的心理測量驗證測試，這導致使用兒童測試的研究存在不確定性，比如自閉癥診斷觀察時間表。”此外，可能需要混合方法，以便接觸到獨立生活和群體環(huán)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.

美國疾病控制與預防中心根據(jù)醫(yī)學報告、來自家長和學校的信息對兒童自閉癥進行定期調查。最近的一次是在2016年，發(fā)現(xiàn)1.85%的8歲兒童被診斷為自閉癥。也就是1 / 54的8歲兒童。

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

在對成年人的調查中，美國疾病控制和預防中心的團隊使用了兒童自閉癥的估計值。

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

研究小組說，因為這是一個估計值，真實數(shù)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.

美國疾病控制與預防中心說:“這項研究的結果可以幫助各州確定診斷自閉癥的必要性，并為美國仍未確診為自閉癥譜系障礙的成年人提供服務。”
