ARIC: decline in stroke incidence rates in older US adults from 2011–2017


  • Stroke incident rates in black and white adults ≥65 years (i.e., older individuals) continue to decline, consistent with previously reported data for 1987–2011 from the Atherosclerosis Risk in Communities (ARIC) cohort.

Why this matters

  • The ARIC cohort study has shown that stroke incidence rates in the US declined from 1987–2011 among people aged ≥65 years, with no significant changes in the younger population.

  • It is important to understand if this trend has continued beyond 2011, given the increasing older population.
