格拉斯哥大學的研究人員發現患有自閉症或閱讀障礙等病症的兒童或存在季節性趨勢。格拉斯哥大學與劍橋大學、英國國家衛生服務機構和蘇格蘭政府的研究人員合作，在2006年至2011年期間收集了在蘇格蘭學校就讀的超過80萬名兒童的資料作研究。通過分析學生的母親懷孕記錄，他們發現，母親在冬天開始懷孕其後出生的學生比在夏天的更有可能需要接受特殊教育。他們的研究結果顯示，在每年第一季度懷孕而出生學生中有8.9％有學習障礙，相比之下，7月至9月間的則佔7.6％。

Children conceived during cloudy winter months, when mothers get less vitamin D, are more likely to have learning disabilities, according to research.
Researchers at the University of Glasgow discovered the seasonal pattern among children with autism or conditions such as dyslexia. Working with researchers at Cambridge University, the U.K.’s National Health Service and the Scottish government, the scientists studied more than 800,000 children who attended Scottish schools between 2006 and 2011. By analyzing the students’ mothers’ pregnancy records, they found that kids conceived in the winter were more likely to have special educational needs than those conceived in the summer. Their findings showed 8.9 percent of students conceived in the first quarter of the year had learning disabilities, compared to 7.6 percent of kids conceived between July and September.
The research is published in the American Journal of Epidemiology.
