Abstract
Education is associated with longer life and less disability. Living longer increases risks of cognitive impairment, often producing disability. We examined associations among education, disability, and life expectancy for people with cognitive impairment, following a 1992 cohort ages 55+ for 23 063 person-years (Panel Study of Income Dynamics, n = 2165). We estimated monthly probabilities of disability and death for 7 education levels, adjusting for age, gender, ethnicity, and cognitive status. We used the probabilities to simulate populations with age-specific cognitive impairment incidence and monthly disability status through death. For those with cognitive impairment, education was associated with longer life and less disability. Among them, college-educated white women lived 3.2 more years than those with <8 years education, disabled 24.4% of life from age 55 compared with 36.7% ( P < .0001). Increasing education will lengthen lives. Living longer, more people will have cognitive impairment. Education may limit their risk of disability and its duration.
