Background Many older adults experience decline in function, but maintain high levels of life satisfaction. The factors associated with high life satisfaction among those with functional impairment are not well understood. Objective Examine the proportion of older adults with functional impairment reporting high life satisfaction and the predictors of high life satisfaction. Design Cross-sectional cohort study. Setting Health and Retirement Study. Subjects A total of 7,287 community-dwelling participants, 65 years or older, who completed the leave-behind questionnaire in 2014 or 2016. Methods The main predictor was having difficulty or needing help in performing Activities of Daily Living (ADL). The primary outcome was reporting high life satisfaction, defined using a three-item Diener scale. Significant factors were identified using modified Poisson regression models adjusted for demographic characteristics. Results Those with no ADL impairment were more likely to report high levels of life satisfaction than those with ADL difficulty or ADL dependence (54.4 vs 38.6 vs 27.6%, P < 0.001). Among those with ADL dependence, we identified several factors associated with high life satisfaction, including: not being lonely (38.2 vs 23.2%, ARR = 1.6 (1.2, 2.2)), satisfied with family life (35.1 vs 12.8%, ARR = 2.7 (1.6, 4.4)), and satisfied with financial situation (40.8 vs 16.6%, ARR = 2.5 (1.8, 3.6)). Similar associations were present among those with ADL difficulty. Conclusions A substantial proportion of older adults with ADL impairment report high life satisfaction, and it is associated with social and economic well-being. Understanding the factors associated with high life satisfaction can lead to clinical practices and policy guidelines that promote life satisfaction in older adults.

日常生活活动受损的老年人的生活满意度

背景 许多老年人的功能下降，但仍保持高水平的生活满意度。与功能障碍者的高生活满意度相关的因素尚不清楚。目的检查报告高生活满意度的功能障碍老年人的比例和高生活满意度的预测因素。设计横断面队列研究。设置健康和退休研究。受试者 2014 年或 2016 年，共有 7,287 名 65 岁或以上的社区居民完成了留守调查问卷。方法 主要预测因素是在进行日常生活活动 (ADL) 时遇到困难或需要帮助。主要结果是报告使用三项 Diener 量表定义的高生活满意度。使用针对人口特征调整的修正泊松回归模型确定了重要因素。结果 没有 ADL 障碍的人比有 ADL 困难或 ADL 依赖的人更有可能报告高水平的生活满意度（54.4 对 38.6 对 27.6%，P < 0.001）。在依赖 ADL 的人群中，我们确定了与高生活满意度相关的几个因素，包括：不孤独（38.2 vs 23.2%，ARR = 1.6（1.2, 2.2）），对家庭生活感到满意（35.1 vs 12.8%，ARR = 2.7） (1.6, 4.4))，并对财务状况感到满意 (40.8 对 16.6%，ARR = 2.5 (1.8, 3.6))。在有 ADL 困难的人中也存在类似的关联。结论 很大一部分患有 ADL 障碍的老年人报告生活满意度高，并且与社会和经济福祉有关。
