Conclusions

In conclusions, The incidence of hip fracture in Okinawa was relatively higher than in other perfecture in Japan, but lower than in caucasian populations. Age-related bone loss occurs both at the trabecular and cortical bone with an accerelation at perimenopausal age in women. Osteoporotics show lower values of bone mineral density than control subjects. But it is difficult to discriminate osteoporotics from control only by BMD values at older age.

The most important factor to determine the present bone mineral density must be adequate daily calcium intake and daily activity through life.
