To determine the prevalence of mild visual impairment (MVI) among urban older adults in primary care settings, and ascertain whether MVI was a risk factor for inadequate performance on self-care health tasks.
We used data from a cohort of 900 older adults recruited from primary care clinics. Self-management skills were assessed using the Comprehensive Health Activities Scale, and vision with corrective lenses was assessed with the Snellen. We modeled visual acuity predicting health task performance with linear regression.
Normal vision was associated with better overall health task performance ( p = .004). Individuals with normal vision were more likely to recall health information conveyed via multimedia ( p = .02) and during a spoken encounter ( p = .04), and were more accurate in dosing multi-drug regimens ( p = .05).
MVI may challenge the performance of self-care behaviors. Health care systems and clinicians should consider even subtle detriments in visual acuity when designing health information, materials, and devices.
确定基层医疗环境中城市老年人轻度视力损害（MVI）的患病率，并确定MVI是否是自我保健健康任务表现不佳的危险因素。
我们使用了从基层医疗诊所招募的900名老年人队列的数据。使用综合健康活动量表评估自我管理技能，使用斯内伦视力表评估矫正视力。我们用线性回归模型预测视力对健康任务表现的影响。
正常视力与更好的整体健康任务表现相关（p = 0.004）。视力正常的个体更有可能回忆起通过多媒体传达的健康信息（p = 0.02）以及在口头交流中传达的信息（p = 0.04），并且在多药疗法给药方面更准确（p = 0.05）。
MVI可能会对自我护理行为的表现构成挑战。医疗保健系统和临床医生在设计健康信息、材料和设备时应考虑到视力方面即使是细微的损害。
