BACKGROUND: /Aims: In this nationwide population-based study, we investigated the risk of vertebral and hip fractures in patients with inflammatory bowel disease (IBD).
METHOD: Using data from the Korean National Health Insurance claims database gathered between 2007 and 2016, we calculated the incidence rate ratios (IRRs) of vertebral and hip fractures in patients with newly diagnosed IBD (n=18,228; 64.1% male, 65.9% ulcerative colitis [UC]) compared with an age- and sex-matched control population (matching ratio, 1:10; n=186,871).
RESULTS: During a median follow-up of 4.5 years, the incidence rate and IRR of vertebral and hip fractures in patients with IBD were 2.88/1,000 person-years and 1.24 (95% CI, 1.08-1.42), respectively. The cumulative risk of vertebral and hip fractures in IBD patients was 0.6%, 1.4%, and 1.9% at 2, 5, and 7 years after diagnosis, respectively, and this risk of fracture in IBD patients was higher than that in matched controls (p=0.002). The use of corticosteroids further increased the risk of fractures in IBD patients (IRR, 1.37; 95% CI 1.13-1.65) compared with matched controls. The risk of fractures was significantly higher in patients with Crohn's disease (CD) (IRR, 1.56; 95% CI, 1.19-2.04) than in matched controls, and this risk remained higher in patients with CD without corticosteroid exposure (IRR, 1.62; 95% CI, 1.12-2.34). The risk of fracture increased with age and was particularly high in females and those with comorbidities.
CONCLUSIONS: The risk of fractures was significantly high in newly diagnosed IBD patients, especially in those with CD regardless of corticosteroid exposure.
