Disability in activities of daily living (ADL) might be more prevalent among elderly with low income due to higher prevalence of chronic diseases and impairments, as well as stronger associations of these factors with ADL-disability.
In the Leiden 85-plus Study, we defined disability as being unable to perform one or more basic ADL activities. Presence of chronic diseases was obtained from medical records, impairments were assessed with performance-tests.
Elderly with low income had higher prevalence of ADL-disability (23% versus 12%; odds ratio 2.0; 95% confidence interval 1.3-3.2), higher prevalence of impairments and equal prevalence of chronic diseases, except for dementia and co-morbidity. Associations of these factors with ADL-disability were not stronger.
We conclude that ADL-disability is more prevalent in elderly with low income. Neither prevalence of chronic diseases nor the association with disability could explain this.
由于慢性病和身体机能障碍的患病率较高，以及这些因素与日常生活活动（ADL）残疾之间更强的关联，低收入老年人在日常生活活动方面的残疾可能更为普遍。
在莱顿85岁及以上研究中，我们将残疾定义为无法进行一项或多项基本日常生活活动。慢性病的存在通过医疗记录获取，身体机能障碍通过性能测试进行评估。
低收入老年人的ADL残疾患病率更高（23%对12%；优势比2.0；95%置信区间1.3 - 3.2），身体机能障碍患病率更高，慢性病患病率相同，但痴呆和共病除外。这些因素与ADL残疾之间的关联并不更强。
我们得出结论，ADL残疾在低收入老年人中更为普遍。慢性病的患病率及其与残疾的关联都无法解释这一现象。
