a
Model 1 adjust for the covariates of age, gender and physical activity level.
b
Model 2 adjust for the covariates of diabetes, hypertension and family history of osteoporosis.
c
Model 3 adjust for the covariates of smoking, drinking alcohol, renal function and 25(OH)D status.
d
Model 4 is a fully‐adjusted model.
e
The optimal cut‐off value of SII is 530.09; SII, systemic immune‐inflammation index; 25(OH)D, 25‐hydroxyvitamin D.
