Background. To explore the prevalence of bone loss among patients with rheumatoid arthritis and healthy controls and further explored the risk factors for osteopenia and osteoporosis of RA patients. Methods. A cross-sectional survey was undertaken in four hospitals in different districts in South China. Case records, laboratory tests, and bone mineral density (BMD) results were included. Multivariable logistic regression analysis, least absolute shrinkage, selection operator (LASSO), and random

RA patients had lower BMD in almost detective sites than healthy controls; the decline of lumbar spine BMD was earlier than HC. RA patients were more likely to comorbid with osteopenia and osteoporosis (p for trend <0.001) in the lumbar spine than HC. Higher serum 25-hydroxyvitamin D3 level and using tumor necrosis factor inhibitor in the last year, aging, lower body mass index, and increased serum uric acid were associated with bone loss.Conclusions. RA patients were more prone and earlier to have bone loss than HC. More attention should be paid to measuring BMD in RA patients aging with lower BMI or hyperuricemia. Besides, serum vitamin D and all three detective sites are recommended to check routinely. TNFi usage in the last year might benefit bone mass.
