摘要
Objective: To determine whether there is an increased risk of hip fracture associated with the use of proton pump inhibitors in a Mediterranean area after adjusting for other potential risk factors. Methods: Retrospective multicenter case-control study carried out in 6 primary health care centers in Catalonia, Spain. Cases were patients aged 50 years and over with a fragility hip fracture registered between January 2007 and December 2010, matched with 2 controls by sex and age. Data collected: use of proton pump inhibitors (type, dosage) in the 5 years previous to the hip fracture, socio-demographic data, body mass index, alcohol and tobacco consumption as well as health conditions and drugs associated with an increase risk of fragility hip fracture. Results: 358 cases were matched with 698 controls. The mean age was 82 years old in both groups. Women represented 77.1% in the case group and 76.9% in the control group. Crude association between proton pump inhibitors and hip fracture was 1.44(95% CI, 1.09-1.89) and adjusted OR was 1.24 (95% CI, 0.93-1.65). No association was found with the continuous or discontinuous use of proton pump inhibitors, OR 1.17 (95% CI, 0.77-1.79), and OR of 1.16 (95% CI, 0.85-1.60) respectively. No association was found when restricting the analysis by sex, OR of 1.19 (95% CI, 0.27-5.14) or by age, younger or older than 80 years, OR of 0.72 (95% CI, 0.24-2.15). Conclusion: The use of proton pump inhibitors was not associated with an increased risk of hip fracture after adjusting for other risk factors in a Mediterranean area. This result suggests the existence of protective environmental factors linked to this southern area of Europe that eventually could compensate for the potential harm produced by proton pump inhibitors.
