Bold variables indicate P-value < 0.05. Model 1: unadjusted model; Model 2: age, sex, and race were adjusted; Model 3: age, sex, race, education level, income level, BMI, smoking status, alcohol consumption, hypertension, diabetes, blood calcium level, serum 25-hydroxyvitamin D, RA, cancer, use of glucocorticoid, family history of osteoporosis, previous fractures, physical activity level, calcium intake level, and vitamin D intake level were adjusted. BMD, bone mineral density; CI, confidence interval.
