抄録
　対人交流が心身の健康に影響を及ぼす過程に睡眠の質の媒介が考えられている。本研究はコロナ禍における対人交流と睡眠の経時的関係を，主観と客観の両面から睡眠を評価することで検討した。【方法】スマートウォッチを用いて74名（平均年齢：22.8±2.35歳）に1か月間の縦断調査を行った。【結果】ベースラインの統制をした上でも，オンライン対人交流の頻度が客観的睡眠の質の向上を有意に予測した一方で（p＜0.05），主観的睡眠（PSQI総合得点）は予測しなかった。【考察】これらはインターネットの利用の仕方次第で健康に良好な影響を及ぼす可能性と，客観的睡眠評価のバイオマーカー指標としてのスマートウォッチの有用性を示唆した。
