Prevalence of dementia in older latinos: the influence of type 2 diabetes mellitus, stroke and genetic factors
Haan MN, Mungas DM, Gonzalez HM, Ortiz TA, Acharya A, Jagust WJ.. Journal of the American Geriatrics Society, 2003-02-01
Topic: Risk, prevention and care in population studies
Results Overall dementia prevalence was 4.8%. Education and Anglo cultural orientation was negatively associated with dementia risk. Those with any E4 and 4-4 combinations had a higher risk for dementia than those with the E3-3 combination.
Key findings
- Results Overall dementia prevalence was 4.8%.
- Education and Anglo cultural orientation was negatively associated with dementia risk.
- Those with any E4 and 4-4 combinations had a higher risk for dementia than those with the E3-3 combination.
Why it matters
In this study of older Latinos, 4.8% had dementia. More education and a stronger "Anglo cultural orientation" were associated with lower dementia risk, and people with any APOE E4 variant, including two copies (4-4), had higher risk than those with the E3-3 combination. These are associations in one group of people, not causes; the title also mentions type 2 diabetes and stroke, but the summary stored here does not report what was found for them.
