It is known that overweight is installed in much more precocious ages and with a longer life expectation, population aging has resulted in the prevalence of osteoporosis and resulting fractures.

It was performed a dietary survey through a three day food recall and obtained the bone age through the application of the Greulich & Pyle Method (1959). Those considered overweight, obese and extremely obese performed evaluation about the Bone Mineral Content (BMC g) and Bone Mineral Density (BMD g/cm2) evaluations through Dual Energy Xray Absorptiometry (DXA), obtained in Lumbar Spine (L1-L4), Proximal Femur, Body Subtotal and Body Total. All the procedures were done according to parental and patient approval and agreement by signing a Free Consent Form and have it clarified.
