Association Between Blood Pressure and Later-Life Cognition Among Black and White Individuals.

ABSTRACT:

Importance

Black individuals are more likely than white individuals to develop dementia. Whether higher blood pressure (BP) levels in black individuals explain differences between black and white individuals in dementia risk is uncertain.

Objective

To determine whether cumulative BP levels explain racial differences in cognitive decline.

Design, setting, and participants

Individual participant data from 5 cohorts (January 1971 to December 2017) were pooled from the Atherosclerosis Risk in Communities Study, Coronary Artery Risk Development in Young Adults Study, Cardiovascular Health Study, Framingham Offspring Study, and Northern Manhattan Study.
