Abstract

【目的】75歳以上の高齢者における新規要介護認定の発生に対する歩行能力の影響を明らかにすることを目的とした。【方法】要介護認定を受けていない75歳以上の地域在住高齢者190名を対象とした。ベースライン調査として5m歩行時間(通常速度)を測定し,以降39ヵ月間の要介護認定発生状況との関連を調べた。【結果】39ヵ月間で34名(17.9%)が新規に要介護認定を受けた。5m歩行時間を男女別に4分位で速い群から遅い群のI〜IV群に分類し,要介護発生率曲線の差をLog-rank検定にて検討した結果,5m歩行時間が遅いIV群(男性5.2秒以上,女性5.8秒以上)では,それ以上に速い歩行速度を有する群(I〜III群)と比べて有意に高い要介護認定発生率を認めた(p<0.01)。Cox回帰分析の結果,新規要介護の発生と有意な関連を認めた変数は,BMIと5m歩行時間(秒)であり,5m歩行時間のハザード比は1.65(p<0.01)であった。【考察と結論】地域在住後期高齢者の歩行速度は,将来の要介護認定発生に影響を与える要因のひとつであることが確認された。

Purpose: The aim of this study was to determine the relationship between 5-m walking time and the need for long-term care among community-dwelling adults aged above 75 years. Methods: A total of 190 older individuals living aged≥75 years (mean age, 80.1 [SD 4.2] years) and living at home participated in this study. Inpatients and current recipients of long-term care were excluded. In the baseline survey, participants performed the 5-m walking test and were followed-up for 39 months. Results: During the 39-month follow-up, 34 participants (17.9%) were certified for long-term care need. The log-rank test of survival curves indicated that the number of subjects certified for long-term care during the follow-up period was significantly higher in the slower walking speed group than in the faster walking speed group (p<0.001). Cox's proportional hazard model revealed that the 5-m walking speed and body mass index were significantly associated with the need for long-term care during the 39 months follow-up period, and the hazard ratio of 5-m walking speed was 1.65 (p<0.01). Discussion and Conclusion: These results suggested that the slow usual walking speed could relate to the future need for long-term care in community-dwelling older adults.
