Trends in disability among older Americans has declined since the 1980s. The study examines whether the trend continues to decline and whether educational disparities exist in the prevalence of functional limitations.
I used the 2000-2014 National Health Interview Survey and included adults aged ≥65 years. Functional limitations was measured by three outcomes: the need for help with activities of daily living (ADLs) or instrumental activities of daily living (IADLs) and physical function limitations. I used a set of logistic models to estimate the average annual change rate of functional limitations. I examined whether the annual rate of change differed by education, age group and sex.
During 2000-2014, the annual increase rate of ADL limitations was 1.7% (P < 0.001) and was 2.0% (P < 0.001) for physical function limitations; IADL limitation did not change significantly. All subgroups experienced an increase in ADL and physical function limitations except for adults with a more than high school education. The lower-educated group had a higher proportion and a higher annual rate of increase in all outcomes. Increasing trends in chronic conditions may contribute to the increasing trend in functional limitations.
The study highlighted a large educational disparity in late-life disability among older Americans.
自 20 世纪 80 年代以来,美国老年人的残疾趋势有所下降。本研究旨在探讨这一趋势是否持续下降,以及在功能障碍的流行程度方面是否存在教育差异。
本研究使用了 2000-2014 年全国健康访谈调查的数据,纳入了年龄≥65 岁的成年人。功能障碍通过三个结果来衡量:日常生活活动(ADL)或工具性日常生活活动(IADL)的辅助需求以及身体功能障碍。我们使用了一套逻辑回归模型来估计功能障碍的平均年变化率。我们还检验了教育程度、年龄组和性别是否会影响年度变化率。
在 2000-2014 年期间,ADL 限制的年增长率为 1.7%(P<0.001),身体功能限制的年增长率为 2.0%(P<0.001);IADL 限制没有显著变化。除了受过高等教育以上的成年人外,所有亚组的 ADL 和身体功能障碍都有所增加。受教育程度较低的群体在所有结果中都有更高的比例和更高的年增长率。慢性疾病的增加趋势可能导致功能障碍的增加趋势。
本研究强调了美国老年人晚年残疾方面存在较大的教育差异。
