Association between dietary B vitamins intake and age-specific blood pressure: A cross-sectional study in American adults.

ABSTRACT:

Objective

To explore the relationship between B vitamins and blood pressure across distinct age groups.

Methods

We analyzed 3654 participants aged ≥20 years after excluding pregnant/lactating individuals and those with incomplete data. B-vitamin intake was calculated from two 24-hour dietary recalls and supplement surveys. Exposure variables included 7 kinds of B vitamins intake, while outcomes comprised hypertension prevalence, systolic and diastolic pressure. The covariates include basic demographics, lifestyle factors, chronic Comorbidities, and nutrient intake. Based on the cross-sectional study, the statistical analyses incorporated NHANES sampling weights. Weighted logistic regression evaluated hypertension association, while linear regression assessed systolic/diastol
