A total of 2422 participants were included in the analysis, with dietary vitamin B1 intake being determined by averaging two 24-h dietary recalls.

Test-specific and global cognition z score was created. Multivariate linear regression models were used to explore the association between vitamin B1 and cognitive function. Results 2422 participants, aged 60 years and older, were included from NHANES across two survey cycles (2011–2014). Higher vitamin B1 intake was associated with higher DSST, AFT scores (P
