When people think about bone health, they often focus on older age, but research shows that the choices you make in midlife can have a lasting impact on your risk of fractures many years down the road. A recent long-term study adds to what we already know about how lifestyle habits affect bone health and fracture risk. Nearly 13,000 men were followed for several decades, and the results found that midlife habits, including physical activity levels and body weight, were strongly linked to hip fracture risk decades later. In fact, these early lifestyle factors helped predict fracture risk up to 50 years later. While the study focused on men, the message applies to everyone. Bone health is built and maintained over time, and midlife is a critical window to support it.
