Vitamin D insufficiency increases bone turnover markers and enhances bone loss at the hip in patients with established vertebral osteoporosis

Abstract

These results show that there is a high prevalence of vitamin D insufficiency in the active community dwelling elderly with established vertebral osteoporosis presenting to clinical attention, which leads to increased bone turnover, decreased BMD at the hip and thus enhanced risk of further osteoporotic fractures in comparison with vitamin D sufficient subjects.
