Circulating bone turnover markers not linked to hip fracture risk shows study

first_imgJun 20 2018The evidence that circulating levels of markers of bone turnover correlate with hip fracture risk among postmenopausal women is limited. In a new Journal of Bone and Mineral Research study, neither serum C-terminal telopeptide of type I collagen (CTX) nor serum procollagen type 1 aminoterminal propeptide (PINP)–two markers of bone turnover– were associated with hip fracture risk.The findings are consistent with results of 5 out of 6 previous studies; however, this study was the first study to examine associations between PINP and CTX and hip fracture risk using serum samples collected in the fasting state, in accordance with the International Osteoporosis Foundation/International Federation of Clinical and Laboratory Medicine Bone Markers Working Group recommendations.
