Hispanic and Black adults had significantly higher odds of stroke compared to non-Hispanic White adults, with adjusted odds ratios of 1.57 and 1.30, respectively.

BACKGROUND: Worldwide, stroke is considered the second leading cause of death, accounting for 11.8% of all deaths in 2013. In the Unites States (US), approximately 795,000 people have a stroke every year. Stroke has many different risk factors that vary by race/ethnicity. There is limited contemporary published literature about the prevalence of stroke among racial/ethnic groups in the US adult population. OBJECTIVE: This study aimed to determine the association between race/ethnicity and the prevalence of stroke among US adults in 2015. METHODS: This study was an observational, non-concurrent prospective of the Behavioural Risk Factor Surveillance System (BRFSS) in 2015 to assess the association between race/ethnicity and the prevalence of stroke. The final study sample was 432,814 US adults ≥ 18 years old. Variables were excluded from the model if there were missing, refused, or did not know responses to the variables of interest. A binary logistic regression analysis was used to obtain odds ratios (OR) and 95% confidence intervals (CI) for the association between race/ethnicity and stroke. The Chi-square test was used to study bivariate associations between categorical variables. The collinearity was assessed. A p-value of <0.05 was considered statistically significant. Statistical analysis was completed using STATA version 14 (Stata Corp, College Station, TX). RESULTS: The highest proportion of participants (43%) were ≥ 44 years old with a balanced distribution of males and females. The highest proportion of stroke was found among Hispanics (4.2%) and non-Hispanic Blacks (4.1%) as compared to 3.2% among non-Hispanic Whites (p<0.001). Furthermore, Hispanics and Blacks were significantly more likely to develop stroke (OR=1.57, 95% CI=1.28-1.91; and OR=1.30, 95% CI=1.16-1.45, respectively) after adjusting for confounding variables. CONCLUSION: Hispanics and Blacks had a higher prevalence of stroke in comparison with non-Hispanic Whites. Further studies are needed to verify these findings and to determine which factors may influence the stroke differences among these racial/ethnic groups.
Aldayel et al. (Mon,) conducted a cross-sectional in Stroke (n=432,814). Hispanic race/ethnicity vs. Non-Hispanic White race/ethnicity was evaluated on Prevalence of stroke (OR 1.57, 95% CI 1.28-1.91, p=<0.001). Hispanic and Black adults had significantly higher odds of stroke compared to non-Hispanic White adults, with adjusted odds ratios of 1.57 and 1.30, respectively.
