ABSTRACT
Objective To explore the association between fatty liver and type 2 diabetes mellitus (T2DM) in the baseline-population of Jinchang cohort study.Methods Data from all the participants involved in the baseline-population of Jinchang cohort study was used,to compare the risks of T2DM in fatty liver and non fatty liver groups and to explore the interaction between family history or fatty liver of diabetes and the prevalence of T2DM.Results Among all the 46 861 participants,10 574 were diagnosed as having fatty liver (22.56％),with the standardized rate as 20.66％.Another 3 818 participants were diagnosed as having T2DM (8.15％) with standardized rate as 6.90％.The prevalence of T2DM increased in parallel with the increase of age (trendx2 =2 833.671,trend P＜ 0.001).The prevalence of T2DM in the fatty liver group was significantly higher than that in the non-fatty liver group,both in men or women and in the overall population.Compared with the group of non-fatty liver,the risks of T2DM in fatty liver group were seen 1.78 times higher in males,2.33 times in women and 2.10 times in the overall population,after adjustment for factors as age,levels of education,smoking,drinking,physical exercise,BMI,family history of diabetes and some metabolic indicators (pressure,TC,TG,uric acid,ALT,AST,gamma-glutamyl transferase).Date from the interaction model showed that fatty liver and family history of diabetes present a positive additive interaction on T2DM (RERI=1.18,95％CI:0.59-1.78;AP=0.24,95％CI:0.14-0.34;S=1.43,95％CI:1.21-1.69).Conclusions Fatty liver could significantly increase the risk of T2DM and a positive additive interaction was also observed between fatty liver and family history of diabetes on T2DM.It was important to strengthen the prevention program on T2DM,in order to effectively control the development of fatty liver.
