Background and purpose Few studies have assessed the role of vitamin D in the association between cardiovascular risk factors and cognitive function. Here, the aim was to investigate the association between cardiovascular health (CVH) and cognitive function according to vitamin D level in a middle‐aged Korean population. Methods This cross‐sectional study included 840 men and 1811 women (mean age 57.2 years) from the Cardiovascular and Metabolic Diseases Etiology Research Center study baseline enrolment (2013–2018). Life's Simple 7 tools from the American Heart Association were used to assess CVH. Cognitive function was evaluated using the Mini‐Mental State Estimation for Dementia Screening (MMSE‐DS), and the serum 25‐hydroxyvitamin D level was measured. Results In the adjusted generalized linear regression models, no significant association between a high Life’s Simple 7 score (4–7 metric at optimal level) and MMSE‐DS score ( β = 0.01, P = 0.93) was found. Amongst men with a high vitamin D level, the high Life’s Simple 7 score group showed a significantly higher MMSE‐DS score ( β = 0.48, P = 0.03). However, amongst men in the low vitamin D group, the association was opposite with no statistical significance ( β = −0.23, P = 0.08). In women, the results were similar, but both strata according to vitamin D level showed no statistical significance. Conclusions Our findings suggest that vitamin D is an effect modifier in the association between CVH and cognition, especially in men.
