COVID-19感染予防対策のための緊急事態宣言が地域在住高齢者の身体の状況，作業参加の状況に及ぼす影響—前向きコホート研究

The impact of a state of emergency to prevent COVID-19 infection on physical conditions and occupational participation of the elderly living in the community: A prospective cohort study

要旨：本研究の目的は，緊急事態宣言下における地域在住高齢者の作業参加を前後比較し，緊急事態宣言が地域在住高齢者の作業参加に及ぼす影響を明らかにすることである．65歳以上の地域在住高齢者に対し広報を実施し対象者を募集し，測定時期によって2群（コロナ前測定群：11名，コロナ期測定群：14名）に群分けした．各群でロコモ25，自記式作業遂行指標（SOPI）を前後比較した結果，コロナ期測定群の追跡調査は，SOPI統制，バランス，満足，余暇活動，生産活動，総得点において，初回調査に比べ有意に低い値を示した（p＜0.05）．本研究により，緊急事態宣言が地域在住高齢者の作業参加に及ぼす影響が明らかとなった．

　The aim of this prospective cohort study was to substantiate the impact of a state of emergency to prevent COVID-19 infection on occupational participation of the elderly living in the community. This study investigated 26 elderly over 65 years old living in the community: 11 before the state of emergency and 14 during the state of emergency. The 25-question Geriatric Locomotive Function Scale and Self-completed Occupational Performance Index (SOPI) were compared before and after in each group. The results indicate that SOPI control, balance, satisfaction, leisure activities, productive activities, and total scores were significantly lower before than after the state of emergency only in the state of emergency group, suggesting the substantial impact of a month-long state of emergency on occupation performance of elderly living in the community.
