The objective of this study was to examine the prevalence and consequences of coexisting vision and cognitive impairments in an Asian population. Data were collected from 4508 community-dwelling Singaporeans aged 60 years and older. Cognition was assessed by the Short Portable Mental Status Questionnaire whereas vision, disability, and self-rated health (SRH) were determined by self-report. Vision impairment was present in 902 (18.5%) participants and cognitive impairment in 835 (13.6%), with 232 (3.5%) participants experiencing both impairments. Persons with the comorbidity experienced higher odds of disability than persons with either single impairment. The association of vision impairment with SRH was stronger among women (odds ratio [OR] = 6.79, 95% confidence interval [CI] = 4.64-9.92) than among men (OR = 1.71, 95% CI = 1.21-2.41). Concurrent cognitive and vision impairment is prevalent in older Singaporeans and is associated with high rates of disability. Gender differences in vision-dependent roles may affect the patient-perceived impact of this comorbidity.
本研究的目的是调查亚洲人群中视力和认知障碍并存的患病率及后果。数据收集自4508名年龄在60岁及以上的新加坡社区居民。认知功能通过简易便携式精神状态问卷进行评估，而视力、残疾状况和自评健康状况（SRH）则通过自我报告确定。902名（18.5%）参与者存在视力障碍，835名（13.6%）存在认知障碍，232名（3.5%）参与者同时存在这两种障碍。与单一障碍患者相比，合并症患者出现残疾的几率更高。视力障碍与自评健康状况之间的关联在女性中（优势比[OR]=6.79，95%置信区间[CI]=4.64 - 9.92）比在男性中（OR = 1.71，95%CI = 1.21 - 2.41）更强。认知和视力障碍并存的情况在新加坡老年人中很普遍，并且与高残疾率相关。依赖视力的角色中的性别差异可能会影响患者对这种合并症的感知影响。
