Studies have shown that bone cortical thickness is decreased in children with autism and other developmental disabilities. However it is not known whether bone mineral density (BMD) of these children is lower; neither is it known whether there is any correlation between BMD and the child's diet. The overall goal of this study is to improve the long term health of children and adolescents with autism spectrum disorder; more specifically the investigators aim to develop a pilot study to investigate the degree to which BMD is impaired in boys with autism and to explore specific additional risk factors. In addition, the aim is to investigate the degree to which BMD is impaired in boys with Autism Spectrum Disorder (ASD) and to explore specific contributing risk factors including nutritional analysis.
