Variation of the Risk Associated With Potentially Modifiable Risk Factors for Dementia Between Ethnic Groups Within One Country. A Retrospective Cohort Study Using Routinely Collected Health Data in Aotearoa New Zealand

Topic: Risk, prevention and care in population studies
Education, smoking, diabetes, depression, physical activity and social isolation were associated with a 1.13-1.55 times increased risk of dementia. We did not demonstrate an association between dementia risk and hypertension, alcohol, or air pollution. Differences between ethnic groups is suggested but not confirmed due to study power. Differences in dementia prevention potential between ethnic groups in NZ are potentially contributed to by both differential prevalence and risk factor effects. Public health strategies must be tailored for the ethnic populations at most risk.

Key findings
- Education, smoking, diabetes, depression, physical activity and social isolation were associated with a 1.13-1.55 times increased risk of dementia.
- We did not demonstrate an association between dementia risk and hypertension, alcohol, or air pollution.
- Differences between ethnic groups is suggested but not confirmed due to study power.
- Differences in dementia prevention potential between ethnic groups in NZ are potentially contributed to by both differential prevalence and risk factor effects.
- Public health strategies must be tailored for the ethnic populations at most risk.
Why it matters
This study found that education, smoking, diabetes, depression, physical activity and social isolation were linked to a 1.13-1.55 times higher risk of dementia, while no link was found for hypertension, alcohol, or air pollution. Differences between ethnic groups were suggested but not confirmed, so prevention strategies may need to be tailored to different populations.
