| Annotation | There is compelling evidence for an inverse relationship between level of education and increased mortality. In contrast to this, one study has shown that for subjects with Alzheimer's disease, those with high education are more than twice as likely to die earlier; however, this result has proven difficult to replicate. In this study, the authors used a representative sample of 10,263 people aged 65+ from the 1991 Canadian Study of Health and Aging (CSHA), to study the relationship between education and mortality to cognitive status. Vital status and date of death were collected at follow-up in 1996, and survival analysis was used with the data collected. The study found that cognitive status modifies the relationship between education and mortality. For those with no cognitive impairment, an inverse relationship between education and mortality exists. Older people with cognitive impairment but no dementia, or those with dementia, are more likely to die early than the cognitively normal at baseline, but no relationship exists between education and mortality. These findings do not support previous work that showed a higher risk of mortality in highly educated dementia subjects. (RH). |
