2003 NOV 6 - (NewsRx.com & NewsRx.net) -- The risk of low bone mineral density (BMD) in patients with inflammatory bowel disease (IBD) increases with age, lower body mass index, and severity of disease, according to a new study from the University of Virginia (UVA) Health System released at the 68th Annual Scientific Meeting of the American College of Gastroenterology.
In a study of 163 patients, of whom 14% were African Americans, researchers also found that African American race had a positive correlation with lower bone mineral density.
"Most epidemiology studies of bone mineral density in IBD are from centers with racially homogeneous patient populations," said Lawrence W. Comerford, MD, one of the UVA investigators. "In this study we wanted to determine the risk factors for low BMD in a large, racially heterogeneous cohort of IBD patients."
Patients in the study were screened for bone mineral density using a dual energy X-ray absorptiometry (DEXA) scan. The researchers grouped the patients according to types of IBD and found that among those in the study with Crohn disease, osteopenia (reduced bone density) was found in 48% at the hip and 33% in the spine, while osteoporosis (bone loss) was found in 6% at the hip and 11% at the spine. Among subjects with ulcerative colitis, osteopenia was found in 29% at the hip and 25% at the spine, with osteoporosis found in 8% at the hip and 13% at the spine.
