美國最近進行的一項有關孤獨癥的全國性調查顯示，有30萬名兒童被診斷患上了孤獨癥。這意味著，每1000名美國學齡兒童中，約有5.5人患孤獨癥。 據合眾社日前援引《華盛頓郵報》的報道說，美國疾病控制中心于5月初公布的這一調查結果顯示，患病兒童之間存在著一個較為明顯的性別差異，那就是男孩較之女孩更容易患上孤獨癥，男孩患孤獨癥的幾率是女孩的4倍。 從統計出來的數據來看，富裕的白人家庭的孩子孤獨癥發病率最高。但研究人員對此指出，這個結果可能反映出生活在富裕白人家庭中的孩子更容易得到醫療救護，但它并不能說明兒童孤獨癥實際的發病情況。 報道說，兒童孤獨癥又稱自閉癥，是一種廣泛性發育障礙?；加泄陋毎Y的兒童很難與其他人交流，往往會表現出社會交往障礙、言語表達障礙、興趣范圍狹窄等多種癥狀。 |

That means about 5.5 out of every 1,000 school-age children have been diagnosed with autism. Past estimates have ranged from 1 to 9 out of every 1,000 children, based on smaller studies in individual states or cities. The government-run study released Thursday reports findings from national surveys of tens of thousands of families. The study by the U.S. Centers for Disease Control and Prevention also found boys are nearly four times more likely than girls to be identified with the condition. And it found Hispanics had lower autism rates, though it's possible that may be related to health-care access problems. The study does not attempt to answer whether autism is increasing -- a topic, driven in part by a debate over whether autism is linked to a vaccine preservative. The new research is being published this week in the CDC publication, Morbidity and Mortality Weekly Report. |
