Abstract: Objective To investigate the correlation between seven serum minerals (calcium, iron, phosphorus, potassium, sodium, selenium, manganese) and the risk of non-alcoholic fatty liver disease (NAFLD) in patients with metabolic syndrome (MS). Methods By analyzing the laboratory data of the NHANES database from 2017 to 2018, the variables such as age, gender, race/nationality, marital status, body mass index, smoking status, drinking status, education level, intensity of physical activity, diabetes history and cardiovascular history were included in the model. The Spearman correlation analysis was used to evaluate the cross correlation between biomarkers, and Bayesian kernel machine regression (BKMR) model was used to fit the association between serum minerals and the risk of NAFLD. Results Among the 1661 MS patients included, NAFLD patients were found to have the higher serum selenium and manganese concentrations and the lower serum phosphorus concentrations. The results of the BKMR model showed a positive linear relationship between mineral mixed serum concentration and the risk of NAFLD prevalence. The increase in selenium concentration of a single mineral in the mixture is significantly positively correlated with the risk of NAFLD. When the concentration of other mineral concentrations is fixed, the IQR of serum selenium concentration increases from 2.25 μmol/L to 2.64 μmol/L, and the correlation with the proportion of increased risk of NAFLD is 19.3% (95% CI: 10%~27.5%), 19.1% (95% CI: 11.2%~25.8%), and 17.8% (95% CI: 8.9%~26.3%), respectively. In addition, the research suggests that there may be interactions among selenium, potassium, and phosphorus. Conclusion There is a positive linear relationship between the mixed serum concentration of minerals and the risk of NAFLD, with an increase in serum selenium concentration being significantly positively correlated with the risk of NAFLD.
