Racial Differences in the Association between Parity and Incident Stroke: Results from the REasons for Geographic and Racial Differences in Stroke Study.

ABSTRACT:

Background

Circulatory and vascular changes across consecutive pregnancies may increase the risk of later-life cerebrovascular health outcomes.

Methods

The association between parity and incident stroke was assessed among 7674 white and 6280 black women, aged 45 years and older, and enrolled in the REasons for Geographic and Racial Differences in Stroke Study from 2003 to 2007. Parity was assessed at baseline, and incident stroke was ascertained from physician-adjudicated medical records through September 2014. Cox proportional hazards models were used to estimate hazard ratios (HR) for the association between parity and stroke, adjusting for baseline measures.

Results

At baseline, 12.7% of white women and 16.2% of black women reported 1 live birth, while 8.2% and 19.
