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 a couple of key things to think about in helping children and adolescents make the transition into young adulthood and independence. One of those things is called mastery motivation and we can see mastery motivation early in life. It's the ability to persist in the face of challenge. If you're growing up with a disability, it can be harder to do things. If you are not challenged, if the environment is not set up correctly, or if you don't have the resources, then you start to feel that you can't master certain kinds of tasks.
