Short-term exposure to ambient ozone and stroke hospital admission: A case-crossover analysis.

We evaluated the association between short-term exposure to ambient ozone air pollution and stroke hospital admissions among adult residents of South Carolina (SC). Data on all incident stroke hospitalizations from 2002 to 2006 were obtained from the SC Office of Research and Statistics. Ozone exposure data were obtained from the US Environmental Protection Agency's Hierarchical Bayesian Model. A semi-symmetric bidirectional case-crossover design was used to examine the association between ozone exposure on lag days 0-2 (0 to 2 days before admission) and stroke hospitalization. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). No significant associations were observed between short-term ozone exposure and hospitalization for all stroke (e.g., lag day 0: OR=0.98; 95% CI=0.96, 1.00) or ischemic stroke (lag day 0: OR=0.98; 95% CI=0.96, 1.01). Risk of hospitalization for hemorrhagic stroke appeared to be higher among African Americans than European Americans; however, the majority of these associations did not reach statistical significance. Among adults in SC from 2002 to 2006, there was no evidence of an association between ozone exposure and risk of hospitalization for all stroke or ischemic stroke; however, African Americans may have an increased risk of hemorrhagic stroke.

Differences in Stroke Mortality Among Adults Aged 45 and Over: United States, 2010-2013.

NCHS Data Brief 2015 Jul(207):1-8

Key Findings: •During 2010-2013, the age-adjusted stroke death rate for non-Hispanic black men aged 45 and over (154.8 deaths per 100,000 population) was 54% to 68% higher than the rates for men of the same age in other race-ethnicity groups. The rate for non-Hispanic black women aged 45 and over was 30% to 61% higher than the rates for women of the same age in other race-ethnicity groups. •The age distribution of stroke deaths differed by race and ethnicity. •Stroke death rates were 32% higher in counties in the lowest median household income quartile than in counties in the highest income quartile. •Nonmetropolitan counties had higher stroke death rates than counties at other urbanization levels. •Stroke mortality inside and outside the Stroke Belt differed by race and ethnicity.
