Abstract:
Objective To evaluate the prevalence of low bone mineral density in patients with inflammatory bowel disease(IBD) and to identify its risk factors. Methods A cross-sectional survey was carried out in IBD patients. Anthropemetric measures, biochemical markers of nutrition and bone mineral density measurement were completed for these patients as well as healthy control subjects. Results Seventy-seven Crohn's disease (CD) and 43 ulcerative colitis(UC) patients were enrolled, and 37 healthy volunteers were recruited as healthy controls(HC). The T value of CD patients, UC patients and HC was -1.72±1.20,-1.26±1.12 and-0.62±0.87 respectively and the T value of CD patients was significantly lower than that of HC (P=0.000). The prevelance of osteoporosis in CD, UC and HC was 23.3%, 14.0% and 0 respectively. The prevelance of osteoporosis in CD was higher than that in HC (P=0.003). Logistic regression analysis indicated that low BMI(BMI≤18.4 kg/m~2) was an independent risk factor for osteoporosis both in CD (OR=11.25,95% CI 3.198-39.580, P=0.000) and in UC (OR= 14. 50,95% CI 1.058-88.200, P=0.045) patients. Age, disease duration, clinical activity active index (CDAI), oral steroid therapy, immunosuppressant treatment and serum vitamin D concentration were not found to be correlated with osteoperosis in IBD patients. Conclusions Low bone mineral density is common in both CD and UC patients and low BMI is an independent risk factor for osteoporosis in IBD patients.
