MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Whether an individual loses or gains bone mass is dependent on how much bone is being broken down (by osteoclasts) and being formed (by osteoblasts). Both processes occur simultaneously in the human body. At present, we can measure markers of bone breakdown (resorption) and formation. However, we hypothesized that to better predict the amount of bone mass that will be lost in the future, these markers should be combined in an “index” to reflect both processes, rather than being interpreted in isolation. Indeed, we found that the ability of our new bone balance index predicted future bone loss across the menopause transition better than the bone resorption marker alone.
