SummaryThis study was to investigate the fracture risk of irritable bowel syndrome (IBS) in comparison with non-IBS group. Our results found that IBS group has increased risk for fracture, in particular of the spine, forearm, hip, and hand.IntroductionPatients with IBS might also be at increased risk of osteoporosis and osteoporotic fractures. Up to now, the association between IBS and the risk of fractures at different anatomic sites occurrences is not completely clear. We conducted a population-based cohort analysis to investigate the fracture risk of IBS in comparison with non-IBS group.MethodsWe identified 29,505 adults aged ≥ 20 years with newly diagnosed IBS using the Taiwan National Health Insurance Research Database in 2000–2012. A comparison group was constructed of patients without IBS who were matched according to gender and age. The occurrence of fracture was monitored until the end of 2013. We analyzed the risk of fracture events to occur in IBS by using Cox proportional hazards regression models.ResultsPatients with IBS had a higher incidence of osteoporotic fractures compared with the non-IBS group (12.34 versus 9.45 per 1000 person-years) and an increased risk of osteoporotic fractures (adjusted hazard ratio [aHR] = 1.27, 95% confidence interval [CI] = 1.20–1.35). Site-specific analysis showed that the IBS group had a higher risk of fractures for spine, forearm, hip, and hand than did the non-IBS group. With further stratification for gender and age, a higher aHR value for osteoporotic fractures in the IBS group was seen across all age groups in males, but seen in elderly females. In addition, female, elderly, low income, hypertension, coronary artery disease, cerebrovascular disease, and depressive disorders as independent osteoporotic fracture risk factors in IBS patients.ConclusionsThe IBS is considered as a risk factor for osteoporotic fractures, particularly in female individuals and fracture sites located at the spine, forearm, hip, and hand.
