Context Previous studies have reported lower fracture risks in patients taking 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins). Objective To investigate risk of fracture among statin users. Design Case-control study of data from the General Practice Research Database (GPRD). Setting A total of 683 general clinical practices in the United Kingdom. Patients Cases were 81880 patients aged 50 years or older who had a fracture of the vertebrae, clavicle, humerus, radius/ulna, carpus, hip, ankle, or foot occurring between the enrollment date of their practice into the GPRD and July 1999, paired with 81880 age-sex-and practice-matched controls. Main Outcome Measure Risk of fracture in current users vs nonusers of statins. Odds ratios were estimated from conditional logistic regression and adjusted for smoking, medications and illnesses associated with fracture risk, and body mass index when known. Results The adjusted odds ratio (OR) for current use of statins compared with non-use was 1.01 (95% confidence interval [Cl], 0.88-1.16). For forearm, hip, and vertebral fractures, the ORs were 1.01 (95% Cl, 0.80-1.27), 0.59 (95% Cl, 0.31-1.13), and 1.15 (95% Cl, 0.62-2.14), respectively. Relative to nonuse, a statin dosage of less than 20 mg/d (standardized to simvastatin) was associated with an adjusted OR of fracture of 1.13 (95% Cl, 0.96-1.33) ; this OR was 1.07 (95% Cl, 0.82-1.38) at dosages of 20 to 39.9 mg/d and 0.85 (95% Cl, 0.47-1.
