Association between Serum Free Fatty Acids to HDL-Cholesterol Ratio and Nonalcoholic Fatty Liver Disease: a Cross-Sectional Study by Xuyao Zhang, Ziyan Lv, Juanwen Zhang, Ruoheng Zheng, Yuying Dai, Jiale Qin

Background: This cross-sectional study aimed to investigate the association between serum free fatty acids and high-density lipoprotein-cholesterol ratio (FHR) and nonalcoholic fatty liver disease (NAFLD) in a Chinese population.
Methods: A total of 760 NAFLD subjects and 379 healthy controls who took their annual health checkups were enrolled during 2019. Fasting blood samples were obtained from the population. NAFLD was diagnosed based on hepatic ultrasound examination.
Results: Serum FHR (*100) in NAFLD subjects was significantly higher than that in controls. We found that the serum FHR in NAFLD participants was positively correlated with BMI, DBP, WBC, HGB, ALT, AST, GGT, TG, FPG, UA, and hsCRP. Univariate and multivariate logistic regression analysis showed that FHR was independently associated with the presence of NAFLD. The area under curve (AUC) of the receiver operating characteristic (ROC) curve of FHR for NAFLD was 0.781 with the 95% confidence interval from 0.753 to 0.810. The optimal cutoff point of FHR for predicting NAFLD was 41.14 with 78.8% sensitivity and 77.3%, respectively.
Conclusions: FHR was significantly associated with NAFLD and may serve as an effective indicator in NAFLD patients.
