[Risk factors for osteoporosis in men from the Fujiwara-kyo Osteoporosis Risk in Men study].

Osteoporosis is a major public health issue not only in women but also in men. Risk factors for low bone mineral density(BMD)need to be identified in men. We have examined factors related to BMD in the Fujiwara-kyo Osteoporosis Risk in Men study. Smoking habit was associated with low BMD. Moderate alcohol intake(<55 g/day), greater milk intake and greater natto intake were associated with high BMD. Non-smoking, greater milk intake and greater natto intake may prevent osteoporosis in men.
