Soluble transferrin receptor (sTfR) is a promising marker representing unmet cellular iron demands. However, whether higher serum sTfR is associated with increased risk of CVDs needs further investigation.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> In the present cross-sectional study, we analyzed data of 4,867 adult participants of the National Health and Nutrition Examination Survey (NHANES) 2017\u20132018. Linear regression models were employed to identify possible correlations between sTfR and other characteristics. The association between sTfR and CVDs was assessed with univariable and multivariable logistics regression models.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The prevalence of CVDs was 9.5% among participants, and higher sTfR levels were found in participants with CVDs (<jats:italic>p<\/jats:italic> &amp;lt; 0.001). Linear regression models revealed positive associations between sTfR and age, body mass index, systolic blood pressure, glycated hemoglobulin A1c, and insulin resistance (all <jats:italic>p<\/jats:italic> &amp;lt; 0.001).
