Abstract
Objective To investigate the association between gallstone and non-alcoholic fatty liver disease (NAFLD)in middle-aged and elderly Chinese. Methods A cross-sectional study was conducted in 8934 Chinese adults from Jiading District, Shanghai. Questionnaire interview, anthropometric measurements, biochemical evaluation, and abdominal ultrasonography were performed in all the participants. Results Compared with participants without gallstone, individuals with gallstone had significantly higher prevalence of NAFLD (28.8% and 42.9%, respectively; P<0.01). Using participants without gallstone as the reference, participants with gallstone were associated with an increased risk of NAFLD after adjustment for multiple covariates [odds ratios(OR)and 95% confidence interval(CI)was 1.39(1.45-1.69)]. In addition, compared with participants without cholecystectomy, participants with cholecystectomy were associated with an increased risk of NAFLD(OR=1.44, 95%CI 1.04-1.99). Conclusion The presence of gallstone and cholecystectomy were positively associated with NAFLD in middle-aged and elderly Chinese.
