Abstract: Background: Many studies have shown that Vitamin E (VitE) intake has beneficial effects on human health, but the relationship between VitE intake and Blood Pressure (BP) is not well understood. Thus, our present study aimed to assess the relationship between VitE intake and hypertension, systolic and diastolic BP in US (United States) adults.

Method: We used data from the 2003-2018 National Health and Nutrition Examination Survey (NHANES). Weighted multivariate regression analysis, subgroup analysis, and Restricted Cubic Splines (RCS) were used to explore the independent associations between VitE intake and hypertension, systolic and diastolic BP. A total of 32,371 participants were included in this study. The mean VitE intake of participants was 8.50 ± 0.08 mg/d. The prevalence of hypertension in subjects was 37.76% and it decreased with increasing VitE intake quartiles (quartile 1: 40.97%, quartile 2: 37.60%, quartile 3: 37.47%, quartile 4: 35.66%). A significant negative correlation was found between VitE intake and hypertension.

Result: We also observed a significant negative association between VitE intake and systolic BP (model 1: β = -0.11, 95% CI: -0.15 ~ -0.07; model 2: β = -0.09, 95% CI: -0.12 ~ -0.05; and model 3: β = -0.05, 95% CI: -0.10 ~ -0.01). Quartile 2 of dietary VitE intake significantly correlated to a lower diastolic BP compared to the lowest quartile of VitE intake (model 3: β = -0.72, 95%CI: -1.26~-0.18).

Conclusion: In US adults, VitE intake has not been significantly found to be associated with hypertension, but it has been found to exhibit a negative association with both systolic and diastolic BP in US adults.
