Outline of Annual Research Achievements

全国の死亡情報、院外心停止情報、および人口50万人以上の救急搬送情報を用いて、大気汚染の健康影響を修飾する要因に関する解析を継続して行った。今年度は、特に大気汚染と気温との相互作用に注目した。大気汚染と気温の相互作用について、高温と低温に層別化した場合の大気汚染の健康影響の違いと、大気汚染が高濃度と低濃度に層別化した場合の気温の健康影響の違いについて検討した。大気汚染(微小粒子状物質、PM2.5およびオゾン)の健康影響は、高気温の時は低気温に比べて増大する可能性が示唆された。逆に、気温の健康影響は、大気汚染の濃度が高いと低い場合に比較して暑熱の健康影響が増大することが示された。一方、寒冷への影響ははっきりしなかった。これらを合わせると、大気汚染および暑熱の相互作用し、健康影響を増大させる可能性があり、気候変動では、このような相互作用を考慮した対応が必要となることが明らかとなった。
一方、大気汚染の健康影響を修飾する要因として、地球環境の評価やモデリングに益するような物理量や指標の推定及びその精度向上を目的として、衛星画像の処理アルゴリズムの開発に取り組んだ。具体的には陸域アルベドや森林の樹高を物理モデルや深層学習を通じて推定し、従来の手法に比べて精度や安定性が向上することが確認できた。さらに、地域のWalkability Indexの評価について、従来欧米で用いられている定義に基づくWalkability indexを用いた予備解析を行い、Indexを疫学研究に用いる場合の課題について検討した。
