Key result
Blood pressure levels were positively correlated with stroke in US adults, with an odds ratio of 1.36 (95% CI 0.95-1.69) in men and 1.45 (95% CI 1.12-1.78) in women.
Why the study?
Hypertension is associated with stroke events, but the correlation between hypertension and stroke needed analysis in US adults using NHANES data from 2007 to 2018.

BP-stroke association in US adults is hypothesis-generating; leaves open causality and practice implications pending longitudinal data.
BACKGROUND: Hypertension is associated with stroke events. The purpose of this study was to analyze the correlation between hypertension and stroke in American adults from 2007 to 2018 in National health and Nutrition Examination Survey (NHANES) database. METHODS: 28528 individuals in the NHANES from 2007 to 2018 were included in the cross-sectional analysis. The independent variable was blood pressure (BP) and the outcome variable was stroke. Multivariate linear regression model was used to study the correlation between BP and stroke. RESULTS: In each multivariate linear regression model, BP level was positively correlated with stroke, and this positive correlation was stable in both men and women (man OR: 1.36, 95% CI: 0.95 to 1.69; woman OR: 1.45, 95% CI: 1.12 to 1.78). CONCLUSION: Our results show that there is a significant positive correlation between BP and stroke. When the systolic blood pressure (SBP) is about 140 mmHg, the risk of stroke is the lowest; Male patients with diastolic blood pressure (DBP) of about 80 mmHg have a lower risk of stroke.

Yan et al. (2022) conducted a cross-sectional in Stroke (n=28,528). Blood pressure was evaluated on Stroke (OR 1.36 (men), OR 1.45 (women), 95% CI 0.95-1.69 (men), 1.12-1.78 (women)). Blood pressure levels were positively correlated with stroke in US adults, with an odds ratio of 1.36 (95% CI 0.95-1.69) in men and 1.45 (95% CI 1.12-1.78) in women.
