BACKGROUNDS
Little is known about the role of frailty in the recovery process of disability among older adults. We examined the association between frailty and recovery from activities of daily living (ADL) and instrumental ADL (IADL) disability among community-dwelling Chinese older adults.
METHODS
Data were from the China Health and Retirement Longitudinal Study. Three waves were used. Participants ≥60 years, had frailty assessment at baseline, and had incident disability in ADL or IADL in 2013, and had disability assessment in 2015 were included. Recovery from ADL and IADL disability were used as outcome measure. Multivariable logistic regression was used to evaluate the potential association between frailty and recovery from ADL or IADL.
RESULTS
We included 516 and 598 participants in the ADL and IADL analysis, respectively. In total, 237 participants recovered from ADL disability and 293 recovered from IADL disability. Nearly half of the non-frail persons recovered from ADL disability, while less than one-quarter of the frail persons had recovery. Over half of the non-frail persons had IADL disability recovery, while only 30% of the frail recovered. After adjustment, the odds of recovery from ADL disability were 59% (95% confidence interval [CI]: 1, 83%) lower among frail participants than those who were non-frail; the odds of recovery from IADL disability were 52% lower among frail persons than those who were non-frail and the association did not reach statistical significance.
CONCLUSIONS
Frailty is an independent predictor of poor recovery from disability among nondisabled community-dwelling older adults in China.
背景
对于衰弱在老年人残疾康复过程中的作用知之甚少。我们研究了衰弱与社区居住的中国老年人日常生活活动（ADL）和工具性日常生活活动（IADL）残疾康复之间的关系。
方法
数据来自中国健康与退休纵向研究。使用了三个波次。纳入标准为：年龄≥60 岁，基线时进行衰弱评估，2013 年发生 ADL 或 IADL 残疾，且 2015 年进行残疾评估。将 ADL 和 IADL 残疾的康复作为结局指标。采用多变量逻辑回归评估衰弱与 ADL 或 IADL 康复之间的潜在关联。
结果
我们分别纳入了 ADL 和 IADL 分析的 516 名和 598 名参与者。共有 237 名参与者从 ADL 残疾中康复，293 名参与者从 IADL 残疾中康复。近一半的非衰弱者从 ADL 残疾中康复，而不到四分之一的衰弱者有康复。超过一半的非衰弱者有 IADL 残疾康复，而只有 30%的衰弱者康复。调整后，与非衰弱者相比，衰弱者从 ADL 残疾中康复的可能性低 59%（95%置信区间[CI]：1，83%）；从 IADL 残疾中康复的可能性低 52%，但关联未达到统计学意义。
结论
衰弱是中国非残疾社区居住的老年人残疾康复不良的独立预测因素。
