Abstract Objective To explore the association of aspartate transaminase (AST) with metabolic syndrome (MS) and its components, in order to provide scientific basis for the early diagnosis of MS. Methods Individuals taken continuous physical examination in Physical Examination Center of Beijing Xiaotangshan Hospital from January 2012 to December 2015 were recruited in the study. Pearson correlation was used to analyze the correlation of baseline AST with MS and its components. The subjects were divided into four groups according to the baseline AST quartile (AST 1-4, from AST lowest to highest). Generalized estimation equation was applied for data analysis. Results There were 2003 males, average of (45.52±14.33) years old; and 2050 females, average age of (42.39±11.72) years old. The incidence of MS was 0.94% in the four years. The average baseline (2012 year) AST level [(19.24±0.12) U/L] was significantly lower than individuals in 2015 [(20.99±0.15) U/L], with statistically significant difference (P < 0.05). Pearson analysis and adjustment of age and other components of MS showed that there were positive correlations between AST and FPG, TG (P < 0.01). Generalized estimation equation revealed that increased AST was positively correlated to the higher risk of MS after age and sex being adjusted (OR=1.00793, 95%CI:1.00351-1.01236, P=0.00043). Conclusion AST is closely correlated with MS and its components, and it can be used as a predictor of MS.
