[Bone mineral density measurement in men]

Multiple vertebral fractures in men can be seen in younger age compared to in women. Also, mortality is higher in men for the case with fracture than in women. Diagnostic criteria with dual x-ray absorptiometry in men is as follows:osteoporosis-less than 70% of young adult mean (YAM), osteopenia- more than 70% and less than 80% of YAM, which is same as diagnostic criteria for women. However, diagnostic criteria for quantitative ultrasound has not been yet established for men. Age, hypogonadism are one of the strong risk factors for low bone mineral density. Although life style such as smoking and excessive alcohol intake is also one of them, coefficient of contribution is not so high.
