Outline of Research at the Start

ビタミンDは現代社会の中で特に不足しがちな栄養素である。われわれは、幼児の「生理的」と言われているO(オー)脚がビタミンD不足に由来すること、ビタミンDサプリメントを使用すると改善が早いことを明らかにしてきた。O脚だけでなく精神発達や免疫機能保持にも重要な栄養素でありながら、われわれのコホートでは、90%がビタミンD欠乏という危機的状況であった。そして、その子ども達の血中ビタミンD濃度も他のコホートと比較して低く、O脚が高率に含まれていた。そこで、本研究では集団を前向きに検討し、妊娠中の母親と生まれてからの子どものビタミンDサプリメントの使用が子どものO脚の程度を軽くするかどうかを検証する。

Outline of Final Research Achievements

The application "TEKUTECH" was designed by the KDDI research team, and its development process and features were presented at the international conference Behavior Change Support Systems 2024 and published as a conference paper.

Currently, post-intervention data analysis is underway. Both the expert information group and the non-expert information group showed a significant increase in serum vitamin D levels compared to non-intervention historical data from our institution. Furthermore, the group that received expert-attributed information demonstrated higher app usage rates and greater behavioral changes related to health. Based on these findings, we plan to further explore the societal value of disseminating health information by experts.

Academic Significance and Societal Importance of the Research Achievements

特に血中ビタミンD濃度が低いと言われている、日本人妊婦に対して、リテラシーを上げることで改善が得られるという成果は、日本全国で行える安全な介入方法が確立されたということに他ならない。
