Examine the association between mobility device use and changes in a frailty index (FI) over one year in community-dwelling older adults with mobility limitations. Analyses utilized 2015-2016 data from the National Health and Aging Trends Study community-dwelling older adults ( = 3934). We calculated a validated 40-item deficit accumulation frailty index (FI) in 2015 and 2016 and compared one year change in FI in older adults with/without canes or walkers using multivariable logistic regression. Analyses were repeated with stratification by baseline frailty. Device use was not associated with worsening frailty in the overall cohort, but was associated with worsening frailty in non-frail individuals when stratified by baseline frailty. Device use does not worsen frailty in individuals who are frail at baseline. Device users who were not frail at baseline experienced worsening frailty suggesting additional contributing factors to their frailty aside from mobility limitations.
研究社区居住的行动不便的老年人在一年中使用移动设备与衰弱指数（FI）变化之间的关联。分析使用了2015 - 2016年国家健康与老龄化趋势研究中社区居住老年人的数据（n = 3934）。我们在2015年和2016年计算了经过验证的40项缺陷积累衰弱指数（FI），并使用多变量逻辑回归比较了使用/未使用手杖或助行器的老年人FI的一年变化。按基线衰弱程度分层重复进行分析。在整个队列中，设备使用与衰弱恶化无关，但按基线衰弱程度分层时，在非衰弱个体中，设备使用与衰弱恶化有关。在基线时衰弱的个体中，设备使用不会使衰弱恶化。基线时不衰弱的设备使用者出现衰弱恶化，这表明除了行动不便之外，还有其他因素导致他们衰弱。
