Association between dietary vitamin B1 intake and stroke risk in older patients: a retrospective cross-sectional study.

ABSTRACT:

Background

Stroke is associated with vitamin B12, folate, and vitamin B1 (VitB1); however, large-scale data supporting the association between VitB1 and stroke risk are lacking. In this study, we aimed to investigate the correlation between VitB1 intake and stroke risk in U.S. adults.

Methods

This retrospective study examined American adults using data from the National Health and Nutrition Examination Survey (NHANES). We analyzed data collected from eight NHANES conducted between 2003 and 2018, focusing on 15,381 participants aged ≥ 60 years. After excluding participants with missing information, the study comprised 11,724 individuals. All data were analyzed using univariate and multivariate logistic regression methods, restricted cubic spline, and sensitivity analyses.
