RESUMO
The calcaneus bone strength was assessed by quantitative ultrasonography in 47 postmenopausal women with type 2 diabetes mellitus (T2DM group) and 30 healthy postmenopausal women (control group).Speed of sound (SOS),broadband ultrasound attenuation (BUA) and stiffness index (SI) in T2DM patients were (1 015 ± 170)m/s,(84 ± 14) dB/MHz and 45 ± 8,respectively,which were significantly lower than those of control group (1 403 ± 232) m/s,(111 ± 18) dB/MHz and 66 ± 12 (all P ＜ 0.001).Stepwise multiple regression analysis showed that homeostasis model assessment of insulin resistance (IR) was independently correlated with the parameters of quantitative ultrasonography in T2DM patients.The results suggest that calcaneus bone strength is reduced in postmenopausal women with T2DM.
