SHBG, Sex Steroids, and Kyphosis in Older Men: The MrOS Study

Accentuated kyphosis is associated with adverse health outcomes, including falls and fractures. Low bone density is a risk factor for hyperkyphosis, and each vertebral fracture adds roughly 4° to forward spine curvature. Sex steroids, in particular low bioavailable estradiol and high sex hormone-binding globulin (SHBG), are associated with bone loss and high SHBG is associated with vertebral fractures in older men. We, therefore, hypothesized...
