Impairment of visual acuity and cognitive function details in elderly hispanics: Results from the hispanic established population for epidemiological study of the elderly (HEPESE), Wave 6, 2006-2007
Methods: Data of 1,542 individuals aged 75 years and above, participating in Wave 6 of the Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE) were analyzed. Scores in seven domains of the Mini Mental State Examination (MMSE) were constructed by contrasting a perfect score with any error. Association with self-reported impairment of visual acuity was assessed using logistic regression and adjusting for gender, age, education, marital status, depression, global health rating, previous stroke, and ADL scores.
Results: Mean age of participants was 83.4 ± 4.8 years, 62.6% (n=965) were females, 38.3% (n=590) were married and 80.4% (n=1237) had 8 or less years of formal education. Mean MMSE score of participants was 20.0 ± 9.0. Individuals with impaired distant vision were more likely to have impaired performance in the cognitive domains of orientation to place (OR 2.01; 95% CI 1.32-3.06, p<0.01), orientation to time (OR 2.58; 95% CI 1.78-3.72, p<0.001), word registration (OR 2.12; 95% CI 1.35-3.33, p<0.05) and recall (OR 1.99; 95% CI 1.30-3.02, p<0.05). Near vision impairment was associated only with impaired performance in the cognitive domain of language (OR 2.10; 95% CI 1.38-4.45, p<0.05).
Conclusion: Near and distant vision impairments are associated with different domain specific cognitive impairment in the elderly.
