TL, telomere length; BMD, bone mineral density.

Model 1: Unadjusted model.

Model 2: age, gender, race, and BMI were adjusted.

Model 3: age, gender, race, BMI, education and smoking were adjusted.

Model 4: age, gender, race, BMI, education, smoking, osteoporosis, DM history, pain drugs intake history, and physical activity level were adjusted.
