Risk factors, ethnicity and dementia: A UK Biobank prospective cohort study of White, South Asian and Black participants.

We find that Black participants were more likely to develop dementia than White participants, but South Asians were not. Identified risk factors in White European origin participants had a similar effect in Black and South Asian origin participants. Volunteers in UK Biobank are not representative of the population and interaction effects were underpowered so further work is needed.
