Our research shows that higher Bone Mineral Density (BMD) was associated with a greater risk of fracture, which is opposite of what we would expect. When we picked apart the BMD ratio we found that bone size had the strongest association with fracture risk, such that smaller bones had a greater risk.
There are multiple factors that impact bone health, including birth weight, nutrition, medications for seizures and/or reflux, genetics, and physical activity. Targeted exercise to improve bone health in childhood can be sustained into adulthood, and childhood is the best time to promote bone health.
