Abstract

OBJECTIVES: To estimate the association between sensory impairment and cognitive decline in older Mexican Americans. DESIGN: A prospective cohort study. SETTING: The Hispanic Established Populations for Epidemiologic Studies of the Elderly from five southwestern states. PARTICIPANTS: The sample consisted of 2,140 noninstitutionalized Mexican Americans aged 65 and older followed from 1993/1994 until 2000/2001. MEASUREMENTS: The outcome, cognitive function decline, was assessed using the Mini-Mental State Examination blind version (MMSE-blind) at baseline and at 2, 5, and 7 years of follow-up. Other variables were near vision, distance vision, hearing, demographics (age, sex, marital status, living arrangements, and education), depressive symptoms, hypertension, diabetes mellitus, stroke, heart attack, and functional status. A general linear mixed model was used to estimate cognitive decline at follow-up. RESULTS: In a fully adjusted model, MMSE-blind scores of subjects with near vision impairment decreased 0.62 points (standard error (SE) = 0.29, P = .03) over 2 years and decreased (slope of decline) 0.13 points (SE = 0.07, P = .045) more per year than scores of subjects with adequate near vision. Other independent predictors of cognitive decline were baseline MMSE-blind score, age, education, marital status, depressive symptoms, and number of activity of daily living limitations. CONCLUSION: Near vision impairment, but not distance vision or hearing impairments, was associated with cognitive decline in older Mexican Americans.
