Abstract
Background
Elevation of serum ferritin levels is frequently observed in non-alcoholic fatty liver disease (NAFLD) patients. Our study aims to examine the association between serum ferritin levels and NAFLD in Korean population.
Methods and results
A total of 25,597 participants were selected from Korean National Health and Nutritional Examination Surveys 2007–2012. The NAFLD liver fat score (NLFS) was used to define NAFLD. Elevation of ALT levels was defined as ALT level > 40 IU/L for male and ALT level > 31 IU/L for female. Multiple logistic regression was used to examine the association of serum ferritin levels and NAFLD by sex. After adjusting for multiple covariates, the ORs (95% CI) of the elevated ALT levels were 1.56 (95% CI: 1.17–2.07), 1.84 (95% CI: 1.39–2.45), and 4.08 (95% CI: 3.08–5.40) for the second, third and fourth serum ferritin quartiles in male (p for trend < 0.01), 1.67 (95% CI: 1.24–2.23), 2.23 (95% CI: 1.68–2.96), and 5.72 (95% CI: 4.32–7.60) for the second, third and fourth serum ferritin quartiles in female (p for trend < 0.01). Serum ferritin levels were also significantly associated with NAFLD and liver fibrosis both in male and female.
Conclusions
Elevation of serum ferritin level is significantly associated with NAFLD and blood ALT elevation in Korean general population.
