Outline of Final Research Achievements

A prospective cohort study was conducted on the onset of developmental disorders such as attention-deficit/hyperactivity disorder and autism spectrum disorder, to examine the associations between behavioral observations by homeroom teachers at nursery schools and kindergartens before entering school and the diagnosis of developmental disorders. It was suggested that the homeroom teacher's behavior observation was related to the diagnosis of developmental disorders. Furthermore, when we examined the relationship between maternal nutritional status of polyunsaturated fatty acids and maternal blood testosterone exposure during pregnancy and developmental disorders, it was suggested that the risk of attention deficit/hyperactivity disorder is high when testosterone levels in maternal blood are high. Considering the incidence of developmental disorders, the number of cases was considered to be still small, and continued observation was considered necessary.

Academic Significance and Societal Importance of the Research Achievements

注意欠如・多動症および自閉スペクトラム症などの発達障害またはその傾向を有する子どもの数が増加しているが、この中で注意欠陥・多動症については就学時まで診断されないことが多く、早期発見と早期治療の必要性が指摘されている。そこで本研究では、就学前の子どもを対象として、保育所・幼稚園での担任による行動観察がその後の注意欠陥・多動症の予見に寄与するのかについて検討を行った。症例数が非常に少ないために結論的なことは得られなかったものの、母親の報告に比較して、担任の評価の妥当性が示唆される結果であり、そのような子への早い段階での働きかけの可能性が示唆された。
