title: [The mineral content in adult radius and ulna in southwestern area of Guang-xi].
abstract: We investigate the BMD of ulna and radius of 2690 persons in southwestern areas of Guang-xi. The results show that the bone mineral content in male is higher than that in female and it is higher in middle-aged person than in the elderly. It is at 32-33 years old that the BMD reaches the peak, then decreases after 35 years old with 5-7 percent and/10 percent loss of the bone mass in male and female per 10 years, respectively. The losing rate of bone mass in female after 50 years old is faster than that in male. In addition, we compared the BMD in workers of different professions at the same age, and found that the heavier the labour intensity, the higher the bone mineral content and the BMD is higher in workers doing outdoor works. The bone mineral content in miners who work in the mine for a long time is lowered. This presentenship that there is a close relationship between the bone mineral content and age, sex, sunshine exposure and intensity of labour.
