Abstract
BACKGROUND: To assess the association between serum sialic acid (SA) levels and nonalcoholic fatty liver disease (NAFLD) in a Chinese population. METHODS: A cross-sectional study was performed among 3,898 Chinese who took their annual health examination. Serum SA levels and other clinical and laboratory parameters were measured. RESULTS: A total of 18.11% fulfilled the diagnostic criteria of NAFLD. NAFLD subjects with/without metabolic syndrome (MS) had significantly higher serum SA levels than those without NAFLD. Serum SA levels were significantly and positively correlated with components of MS (body mass index, systolic blood pressure, diastolic blood pressure, triglyceride and fasting plasma glucose) in the NAFLD group. Stepwise logistic regression analysis showed that SA levels were significantly associated with the risk factor for NAFLD. Serum SA levels were negatively correlated with the FIB-4 score, and lower serum SA levels were independent factors predicting advanced fibrosis in subjects with NAFLD. CONCLUSIONS: Our results showed a significant association between serum SA levels and NAFLD.
