The aim of this study was to determine whether home modification was associated with subsequent progression of frailty and mortality in older adults. We conducted a prospective cohort study in 574 adults 65 and older who required a low or moderate level of care. Of these, 34% modified their homes-most frequently a corridor-and the most common type of modification was the installation of handrails. The mortality was significantly lower among older adults with home modifications than in those without home modifications at 2 years (adjusted hazard ratio [HR] = 0.52; 95% confidence interval [CI] [0.32, 0.87]), 3 years (HR = 0.57, 95% CI [0.54, 0.81]), and 4.7 years (HR = 0.65, 95% CI [0.65, 0.91]). These findings suggest that home modification may prevent the progression of frailty (i.e., need for low/moderate level of care increasing to the need for high level of care) in older adults.
本研究的目的是确定家庭改造是否与老年人衰弱的后续进展及死亡率相关。我们对574名65岁及以上需要低或中等护理水平的成年人进行了一项前瞻性队列研究。其中，34%的人对其房屋进行了改造，最常见的改造部位是走廊，最常见的改造类型是安装扶手。在2年（调整后风险比[HR]=0.52；95%置信区间[CI][0.32,0.87]）、3年（HR=0.57，95%CI[0.54,0.81]）和4.7年（HR=0.65，95%CI[0.65,0.91]）时，进行家庭改造的老年人死亡率显著低于未进行家庭改造的老年人。这些发现表明，家庭改造可能会预防老年人衰弱的进展（即从需要低/中等护理水平增加到需要高水平护理）。
