Risks and predictors of osteoporosis in patients with inflammatory bowel diseases in an Asian population: a
1Department of Surgery, E-Da Hospital and I-Shou University, Kaohsiung, Taiwan.
Background:
We investigated the inflammatory bowel disease (IBD) specific predictors of osteoporosis and pathological fracture by analysing the Taiwan National Health Insurance Research Database.
Methods:
Totally, we enrolled 3141 IBD patients and 12,564 age- and sex-matched controls. We calculated the hazard ratios (HRs) and 95% confidence intervals (CIs) of osteoporosis and pathological fracture in both cohorts.
Results:
Inflammatory bowel disease patients had significantly higher comorbidity-adjusted rates of osteoporosis and pathological fracture compared with controls [adjusted hazard ratio (aHR), 1.31; 95% CI, 1.09-1.60, p = 0.004]. Further analysis indicated that women (aHR, 1.36; 95% CI, 1.09-1.70, p = 0.008), middle-aged patients (aHR, 1.74; 95% CI, 1.25-2.41, p = 0.001), patients with Crohn's disease (aHR, 1.33; 95% CI, 1.09-1.64, p = 0.006) and patients without comorbidities (aHR, 1.81; 95% CI, 1.23-2.67, p = 0.003) exhibited excessive risks of osteoporosis. Moreover, patients requiring hospitalisation for IBD exhibited the highest risk of developing osteoporosis (aHR, 4.46; 95% CI, 2.74-7.27, p < 0.001) and pathological fracture (aHR, 17.1; 95% CI, 5.78-50.9, p < 0.001).
Conclusions:
Patients with IBD, particularly women, middle-aged patients and patients without comorbidities, are associated with a long-term risk of osteoporosis. The risks of osteoporosis and pathological fracture were highest in patients requiring hospitalisation for IBD.
