title: [Etiology and epidemiology of osteoporosis in men].
abstract: One-half to two-thirds of men with osteoporosis have secondary osteoporosis. The most important causes are heavy drinking, medication, and hypogonadism. Bone mineral density (BMD) slowly decreases with age in men, but prevalence of osteoporosis reached more than 20 percents among men aged 80 years and older. BMD is a major predictor for fracture risk in men as well as women, and predictive ability of BMD in men is similar with that in women. Smoking is a stronger predictor for future fracture in men compared with women. Previous fracture, alcohol drinking, steroid usage, and family history have similar predictive ability for fracture risk in both men and women.
