To assess how depression and impaired vision relate to disability in older people.
An epidemiological survey of an age-stratified random community sample.
The rural mid-Monongahela Valley in South-western Pennsylvania.
A total of 872 noninstitutionalized persons aged 68 and older, fluent in English, and with at least a grade 6 education.
Demographics, self-reported vision impairment, OARS Instrumental Activities of Daily Living (IADL), and modified Center for Epidemiologic Studies-Depression scale to assess depression.
Compared with subjects with intact vision, those with impaired vision were more likely to have five or more depressive symptoms (29.7% vs 8.5%; OR = 4.6, 95% CI = 2.2, 9.6) and to be more functionally impaired (OR = 9.7, 95% CI = 4.9, 19.2). The number of depressive symptoms (1-4: OR = 2.4, CI = 1.8, 3.4) and (5+: OR = 5.9, CI = 3.6, 9.8) was associated independently with IADL impairment after controlling for vision, age, and gender.
Impaired vision and depression are both associated strongly with functional impairment in this community population of older adults. Depression, however, increases the odds of functional impairment independent of vision impairment. Treating depression may reduce excess disability associated with impaired vision.
评估老年人的抑郁和视力障碍与残疾之间的关系。
对按年龄分层的随机社区样本进行的流行病学调查。
宾夕法尼亚州西南部的莫农加希拉河谷中部农村地区。
共有872名68岁及以上的非机构化人员，英语流利，至少接受过六年级教育。
人口统计学资料、自我报告的视力障碍、OARS日常生活工具性活动（IADL）以及用于评估抑郁的改良流行病学研究中心抑郁量表。
与视力正常的受试者相比，视力障碍者更有可能出现五种或更多抑郁症状（29.7%对8.5%；OR = 4.6，95%CI = 2.2，9.6），并且功能受损更严重（OR = 9.7，95%CI = 4.9，19.2）。在控制了视力、年龄和性别后，抑郁症状的数量（1 - 4种：OR = 2.4，CI = 1.8，3.4）和（5种及以上：OR = 5.9，CI = 3.6，9.8）与IADL受损独立相关。
在这个老年社区人群中，视力障碍和抑郁都与功能受损密切相关。然而，抑郁会增加功能受损的几率，且独立于视力障碍。治疗抑郁可能会减少与视力障碍相关的额外残疾。
