Abstract
Background
This nationwide population-based study sought to investigate the risk of spine and hip fracture in patients with inflammatory bowel diseases (IBD).
Methods
Using the 2007–2016 data from the Korean national health insurance claims database, we calculated incidence rate and incidence rate ratios (IRR) of spine and hip fracture in patients with IBD (n = 18,228; 64.1% male, 65.9% ulcerative colitis [UC]) compared with age- and sex- frequency matched subjects in 1:10 ratio (n = 186,871). A Cox regression model was used to evaluate risk of spine and hip fracture.
Results
The incidence rate and IRR of spine and hip fracture in IBD were 2.88/1000 person-years and 1.21 (95% confidence interval [CI], 1.11–1.31) during the median follow-up of 4.5 years. The risk for spine and hip fracture was significantly higher in UC (IRR 1.39, 95% CI, 1.25- 1.54), whereas it was not significantly higher in Crohn’s disease (IRR 0.85, 95% CI, 0.67- 1.06) than matched controls. In UC, the IRR of spine fracture was 1.41 (95% CI, 1.24–1.58) and the IRR of hip fracture was 1.40 (95% CI, 1.11–1.71). In multivariable analysis using the Cox regression model, the risk of spine and hip fracture increased with age (p trend < 0.001), in female patients (adjusted hazard ratio [aHR], 1.94; 95% CI, 1.50–2.51) and in patients with comorbidities including osteoporosis (aHR 2.86; 95% CI, 2.10–3.89), stroke (aHR 2.74; 95% CI, 1.78–4.21) hypertension (aHR 1.82; 95% CI, 1.38–2.41), diabetes mellitus (aHR 1.67; 95% CI, 1.25–2.24) and dyslipidaemia (aHR 1.36; 95% CI, 1.05–1.78).
Conclusion
In a population-based study from Korea, we found that the risk for spine and hip fracture increased in patients with IBD, especially in UC patients. Also, this risk increased in patients who are older, female, or have comorbidities.
