Meta-analysis of serum γ-glutamyltransferase levels and risk of metabolic syndrome / 中华内分泌代谢杂志

ABSTRACT

Objective To assess the association between serum γ-glutamyltransferase (γGT) levels and the risk of metabolic syndrome (MS),so as to provide a reference for prevention and diagnosis of MS.Methods Ten papers about the relationship between γGT level and incident MS published in Pubmed,Embase,and the Institute for Scientific Information (ISI),China Academic Journal Full-text Database,China National Knowledge Infrastructure Database and Wan Fang Digital Periodicals Database from January 2000 to April 2014 were retrieved and analysed.Results A total of 65 331 participants from the ten studies were included in the rmeta-analysis.The pooled RR was 2.06 (95％ CI 1.63-2.49) when the incidence of MS was compared between the highest and the lowest groups of γGT levels.A subgroup analysis was made in Asian and western populations.The pooled RR of MS in Asian population was 2.26 (95 ％ CI 1.65-2.87) and in western population it was 1.70 (95 ％ CI 1.15-2.25).Sensitivity analysis confirmed the stability of results.No publication bias was found in our meta-analysis by Egger's and Begg's test.Conclusion Current evidences from prospective studies indicate that risk of metabolic syndrome is increased in correlation with an increase in serum γGT,and serum γGT seems to be an important predictor for MS.
