Osteoporosis Self-Assessment Tool As a Screening Tool for Predicting Osteoporosis in Elderly Chinese Patients With Established Rheumatoid Arthritis

Osteoporosis Self-Assessment Tool for Asians (OSTA) is an indicator for assessing osteoporosis in postmenopausal women. The aim of this study was to investigate the value of OSTA index on predicting osteoporosis in elderly Chinese patients with established rheumatoid arthritis (RA). A total of 320 patients with RA and 158 normal individuals were recruited from January 2015 to October 2017. Bone mineral density (BMD) at the femur and lumbar spine was measured by dual-energy X-ray absorptiometry. RA group and control group were divided into low risk (values ≥−1), medium risk (values between −4 and −1), and high risk (values ≤−4) group according to the value of OSTA index.
