INTRODUCTION: Bone demineralization has been increasingly recognized as a disease process concurrent with inflammatory bowel disease (IBD). Racial variation in osteoporosis in IBD patients has been poorly described. We sought to identify the risk factors for demineralization in Afro-Caribbeans (AC) with IBD.

METHODS: A retrospective chart review was performed from a 10-year prospectively collected database of IBD patients seen at an urban medical center. Data on dual-energy X-ray absorptiometry (DXA) scanning, use of steroids, bisphosphonates, calcium, and vitamin D, as well as blood chemistries were collected.

RESULTS: One hundred and fifteen charts of AC IBD patients were reviewed, of which 24 patients had undergone DXA scanning. Fourteen patients with a T-score of less than -1 were compared with 10 patients with DXA scores of more than -1. Two patients with T-scores of less than -1 had fractures, whereas none were observed in the comparison group (P=0.5). The mean BMI for those with T-scores of less than -1 was 23.9 kg/m compared with 31.5 kg/m in those with T-scores of more than -1 (P=0.0034).

CONCLUSION: Screening for bone demineralization in ethnic populations with IBD is lacking as only 21% of AC IBD patients seen in our institution had undergone a DXA scan. Of those who were scanned, more than half of the patients had T-scores suggestive of bone demineralization. Although those who were obese did not have demineralization, our sample sizes were small and the results from this study should prompt further investigation to determine the prevalence and significance of bone demineralization in minority populations with IBD.
