Objective: The aim of this study was to investigate whether the use of statins was associated with a decreased risk of gallstone disease. Methods: We conducted a population-based casecontrol study in Taiwan. Cases consisted of all patients who were aged 50 years and older and had a first-time diagnosis of gallstone disease or cholecystectomy for the period between 2005 and 2009. The controls were matched to cases by age, sex and index date. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by using multiple logistic regression. Results: We examined 1014 gallstone disease cases and 1014 controls. The unadjusted ORs for any statin prescription was 1.06 (95% CI 0.86 to 1.29), and the adjusted OR was 1.14 (95% CI 0.90 to 1.43). Compared with no use of statins, the adjusted ORs were 1.05 (95% CI 0.72 to 1.54) for the group having been prescribed statins with cumulative defined daily doses (DDDs) below 41.53, 1.12 (95% CI 0.84 to 1.50) for the group with cumulative dose between 41.54 and 334.81 DDD, and 1.30 (95% CI 0.86 to 1.95) for the group with cumulative statin use of 334.81 DDDs or more. Conclusions: This study does not provide support for a beneficial association between usage of statin and gallstone disease.
