Visual impairment is common in adults and its prevalence increases with advancing age. Visual impairment among older adults is associated with functional decline, physical disability, poor overall health and social limitations. Despite the fact that older adults with heart failure are often required to read medication and food labels, use a scale to weigh themselves, identify medications by color, and follow discharge instructions from the hospital, little research has sought to determine the prevalence and risk factors of visual impairment among this patient population. In this study, we will use the 1999-2008 waves of NHANES to 1) Examine the prevalence of visual impairment among older adults with and without heart failure 2) Understand which factors are independently associated with visual acuity among older adults with HF and 3) Examine the limitations in the activities of daily living (ADLs) due to vision, among older adults with heart failure.
