Outline of Final Research Achievements

Based on the results of the add-on cohort of the three-generation cohort of the Tohoku University Medical Megabank Project, we clarified the association between sleep and depressive symptoms during pregnancy and early postpartum period, and created an intervention program for insomnia during pregnancy. Detailed sleep records using a well-labeled device and longitudinal measurement of depressive symptom trends were used to divide the cohort into two groups according to sleep duration: a long-time group and a short-time group, with the short-time group showing a significantly higher incidence of depressive symptoms than the long-time group, among other findings. Based on these findings, a sleep intervention program based on cognitive-behavioral therapy for insomnia and psycho-education on sleep during pregnancy and postpartum was developed for women who are pregnant or thinking of becoming pregnant.

Academic Significance and Societal Importance of the Research Achievements

多くの妊産婦は不眠を経験し、妊娠中の不眠は母体の健康やメンタルヘルス及び胎児への影響が懸念される。妊娠中の不眠症に対する薬物療法はリスクとベネフィットを十分検討する必要があり、妊娠中における非薬物療法的な治療の確立が重要である。
本研究では、ウエラブルデバイスを用いて周産期の睡眠実態を詳細に調査し、抑うつ症状との関連を示した。これらの知見を下に、これらの知見を下に、妊娠中または妊娠を考えている女性を対象とした、不眠症に対する認知行動療法を基盤とし、妊娠中及び産後の睡眠に関する心理教育を追加した睡眠介入プログラムを作成した。
