Outline of Final Research Achievements	Health surveys were conducted targeting the Great East Japan Earthquake survivors in the coastal areas of Ishinomaki City and Wakabayashi Ward of Sendai City, to understand changes in the health status of residents in the affected areas 11 to 13 years after the earthquake. As a result, the percentage of people having sleep disorders and psychological distress was higher than the national average. These proportions were higher among residents of disaster-affected public housing than among residents of their own homes. It was suggested that there are disparities in recovery status and psychological status depending on the living environment. Additionally, a database was created in which personal information was removed from the health survey data of disaster survivors, and the database was made public at the Social Research and Data Archive Research Center attached to the Institute of Social Science, the University of Tokyo.

Academic Significance and Societal Importance of the Research Achievements	大規模自然災害の被災者を対象に居住・経済状況や心身の健康状態などを10年以上にわたって追跡したコホート研究は、国内外でも稀なものであり、学術上貴重な研究資源である。本研究で得られた知見は、自然災害が発生した際の被災者支援を考える際のエビデンスになるという点で社会的意義も大きい。そこで、この貴重な学術資源を最大限活用できるように、個人情報を削除したデータベースを構築し、東京大学社会科学研究所附属社会調査・データアーカイブ研究センターに寄託した。これにより、本研究の学術的・社会的価値がさらに高まることが期待される。
