Outline of Final Research Achievements

The number of children with suspected attention deficit/hyperactivity disorder has increased in recent years. In this study, the environmental factors were examined using an existing birth cohort study. The maternal scoring on child problem behaviors at the age of 3 and a half decreased in the second children, were higher in boys than in girls, and decreased as the parenting environment score was higher. It was observed that the score tended to increase when the child was playing games. However, the behavioral observations at nursery schools and kindergartens confirmed similar results by gender, but their relationship with the home environment score was not clear. On the other hand, the index corresponding to IQ measured by K-ABC II was low in boys and was positively correlated with the child-rearing environment score. These results suggest that avoiding second-hand smoke is still important.

Academic Significance and Societal Importance of the Research Achievements

近年、ADHDまたはその傾向を示す子どもの数が増加しており、その環境要因について出生コホート調査にて縦断的な解析を行った。その結果、ADHDの臨床で確認されているように、男児に多いことなどを再確認するとともに、出生順位や育児環境による影響が示唆されたものの、子どもの行動特徴に関するより客観的な評価と考えられる、保育所・幼稚園での評価では性別以外の要因は明確ではなかった。一方で、認知処理過程などIQに関連する指標では、育児環境や受動喫煙、ゲームの利用などが要因として抽出された。子どもの適切な子育ち環境を確保する上で重要な要因と考えられた。
