Risk of low bone mineral density in patients with rheumatoid arthritis treated with biologics (BMC Musculoskeletal Disorders)

Background: Osteoporosis is a complication of rheumatoid arthritis (RA). We identified risk factors for osteoporosis during treatment with biologics. Methods: Femoral neck bone mineral density (BMD) was measured in 186 patients with biologics-treated RA. We compared the characteristics of those with BMD ≥70 % of young adult mean (YAM) and those with BMD
