研究:八月份出生的孩子更易患多動症
One's birthdate has already been linked to such things as temperament. Now researchers in Taiwan report in the Journal of Pediatrics that we can add ADHD to the list.
事實上，一個人的出生日期與其性格品性等方面都存在一定的聯繫。最近，臺灣研究人員在《中華兒科雜誌》發表的一篇研究報告指出，出生日期與患得多動症之間也具有一定聯繫。
When looking at 378,881 children ages 4 to 17 at some point between 1997 to 2011, they found that preschool and elementary school-age children born in August were 1.65 times More likely to be diagnosed with ADHD and 1.73 times more likely to be put on medication than kids born in September—who, because of school cutoff dates similar to those in the US, tend to be nearly a year older than their August counterparts.
研究人員觀察了378881位出生年份在1997年至2011年間的孩子，他們的年齡分別在4至17歲之間不等。在觀察後他們發現，那些出生在8月的學前班兒童和小學生患得ADHD（多動症）的概率比那些9月份出生的孩子要高1.65倍，今後接受藥物治療的可能性也要比那些9月份出生的孩子高出1.73倍。由於中國學校入學的截止日期與美國基本相同，因此學校內那些9月份出生的孩子普遍比那些在8月份出生的孩子年長一歲。
The discrepancy did not exist in older kids, which researchers write may imply that "increasing age and maturity lessens the impact of birth month on ADHD diagnoses."
這種差異並沒有在年齡較大的孩子身上體現出來，研究人員表示：“隨着年齡逐漸增長，心智也愈發成熟，這些因素都從一定程度上削弱了出生月份與患得多動症之間的關聯。”
The findings add to previous work on ADHD in the US and Canada finding that a child's age within a grade plays a role in ADHD diagnosis, lead author -Hong Chen tells Live Science. He calls it reduced neurocognitive maturity, something that is particularly pronounced when comparing the youngest and oldest kids within a grade.
首席作者陳木宏告訴《生活科學》雜誌：這些發現進一步爲之前美國和加拿大在多動症方面的研究提供了證據支持，即孩子在同一年級的前提下，年齡大小是判斷患有多動症風險大小的關鍵因素。他稱其爲“神經認知成熟度下降”的表現，該名詞在將同年級年齡最大和年齡最小的孩子進行對比時經常被用到。
Globally, the number of kids diagnosed with ADHD has risen dramatically, researchers note in a press release, saying, "Our findings emphasize the importance of considering the age of a child within a grade when diagnosing ADHD and prescribing medication to treat ADHD."
研究人員在新聞稿中提到，目前全球患有多動症孩子的數量正在不斷增長。他們表示，“我們的調查將着重研究同年級之間孩子的年齡大小問題，因爲這個因素在診斷病症和爲治療多動症進行藥物治療的時候顯得尤爲重要。”
More than one in 10 kids in the US have been diagnosed with ADHD.
美國目前十個孩子中就有一個孩子被診斷患有多動症。
