台灣中老年人整體及上下肢身體活動功能障礙與衰弱之相關性分析

本研究以衛生福利部國民健康署「台灣中老年身心社會生活狀況長期追蹤調查」第七波(2011)與第八波(2015)進行分析，對身體活動功能進行單變數分析及複邏輯式迴歸(Multinomial Logistic Regression)，分析身體活動功能與衰弱之相關性；並進行性別及年齡層、獨居之分層分析。本研究透過三種身體活動功能障礙的定義分別為:身體活動障礙、身體活動功能障礙(百分比)、上下肢身體活動功能障礙分別探討對衰弱前期與衰弱之相關性，發現身體活動功能輕度障礙就會對衰弱造成影響，下肢的身體活動功能障礙相較於上肢對於衰弱的影響來得大。

This study analyzes data from the seventh wave (2011) and eighth wave (2015) of the "Taiwan Longitudinal Study on Aging" conducted by the Health Promotion Administration, Ministry of Health and Welfare. The analysis includes univariate analysis and Multinomial Logistic Regression to investigate the relationship between physical function impairments and frailty. Additionally, stratified analyses based on gender, age groups, and living alone status were conducted.The study examines the association between physical function impairments and pre-frailty/frailty using three definitions of physical function impairments: general physical function impairment, percentage of physical function impairment, and upper and lower limb physical function impairments. The findings reveal that even mild impairments in physical functions can impact frailty, with lower limb impairments having a greater effect on frailty compared to upper limb impairments.
