新型コロナウイルス感染症流行下の高齢者の体力の変化~パフォーマンステストを用いた検討~

Abstract: 目的:地域在住高齢者の体力の推移をパフォーマンステストにより把握し,新型コロナウイルス感染症流行下で は平時より顕著な体力低下が生じているのかを明らかにする.方法:2016 年から 2020 年にかけて開催された健 診事業に参加した地域在住高齢者 240 人(男性 107 人,女性 133 人,平均 76.7±5.1 歳)を対象とした.握力(上 肢筋力) ,開眼片足立ち時間(静的バランス能力) ,長座体前屈(柔軟性) ,Timed up and go test(TUG,複合的 移動能力) ,5 m 通常歩行時間(歩行能力) ,48 本ペグ移動(手指巧緻動作)を評価した.線形混合効果モデルを 用い,繰り返し測定データ(レベル 1) ,流行前(2016-2019 年)と流行下(2019-2020 年) (レベル 2) ,個人(レ ベル 3)の階層性を持つデータとして扱った.調査年(レベル 1)の固定効果を求めるとともに,調査年と流行 前・下(レベル 2)のクロス水準交互作用を確認し,2019 年から 2020 年にかけての追加の低下幅(B)を推定し た.結果:有意なクロス水準交互作用が確認された項目は,男性で長座体前屈… Show more

“…While we assumed that the grip strength and walking speed assessed in 2019 would remain unchanged in 2020 in the primary analysis, we performed a sub-analysis assuming that the subject's walking speed and grip strength in 2020 were 5% lower than in 2019 in the sub-analysis, based on previous studies of one-year changes in grip strength and walking speed in older adults. 18,19 Estimation of 95% confidence intervals (CIs) for the prevalence rate of frailty and the discriminant measures for frailty of the questionnaire was conducted using R (the command epi.tests), and the other analyses were performed using IBM SPSS Statistics 27. A significance level of P = 0.05 (the two-tailed test) was used.…”

“…In addition, as sub‐analyses, the discriminant ability of the eight items for physical aspects of frailty (i.e., physical function [Q7–9, 13], nutritional status [Q3, 6], and oral function [Q4–5]) 10 and the 15 items of the original version of the questionnaire 7,8 were examined. While we assumed that the grip strength and walking speed assessed in 2019 would remain unchanged in 2020 in the primary analysis, we performed a sub‐analysis assuming that the subject's walking speed and grip strength in 2020 were 5% lower than in 2019 in the sub‐analysis, based on previous studies of one‐year changes in grip strength and walking speed in older adults 18,19 .
