Outline of Final Research Achievements

Under the theme of protecting families from smoke generated from open fire stoves, the project attempted to promote behavior change to reduce PM2.5 exposure from the perspective of community nursing by combining excellent Japanese digital technologies such as measuring instruments/IoT and analog technologies such as educational contents for children to conduct local fieldwork and intervention.
Although there were some travel postponements due to the corona, in the final year of the project, we were able to conduct the field demonstration (targeting 42 households) as planned and quantitatively evaluate its effectiveness. In the end, we were able to achieve academic results in the following two respects:
i.Promoting health communication within the household to the community, with education at the core. ii. Achievement of interdisciplinary nursing x information engineering by utilizing advanced ICT technology.

Academic Significance and Societal Importance of the Research Achievements

世界では28億人が薪や炭を燃料とする原始的なストーブを使って室内で調理をしており、高濃度のPM2.5曝露により年間400万人が早死する(WHO 2018)。これら死者の5割以上は母子で、呼吸器疾患による5歳以下の子供の死亡原因の半数は室内でのPM2.5曝露に起因すると推定されている。研究代表者らとルワンダ環境省の調査では調理時の室内PM2.5濃度は日平均は150ug/m3程度（米国EPAの指標では「非常に不健康」）と推定された。本調査地域の最終学歴は小学校が過半数で識字率も3割程度である。状況改善のためには、世帯住民が健康情報を理解し、自ら意思決定するための能力を得る新しい方策が求められる。
