Objective Discuss the relationship of bone mineral density (BMD) with bone biochemical markers and testosterone and estradiol in Fujian of Chineses She-zu, and comparing with the Han-zu, in order to provide the basis for prevention and treatment of osteoporosis in the region. Methods Select healthy adults over 20 years old from the gathering place of Chinese She- Zhu,including The Chinese She-Zhu 1371 and Chinese Han 1432. Use DTX-200 BMD absorptiometry ( made in Osdeometer Medi Tech company of USA) detect the BMD. Measuring content of BMD, 25 (OH) D3, BGP, E2, T, PTH, P1NP, ALP. The date was analyzed with the application SPSS17. 0 software package. Results Average density decreases were increasing with age regardless of She-zu or Han-zu, Men are higher than women in same age. The women of Han-zu are higher than She-zu in same age in addition to the age of 40-49,No Significant differences between Han-zu and She-zu(P >0. 05) ,BMD in males of She-zu reached in a peak at 40 -49 years old group and of Han-zu reached in a peak at 30-39 years old group. 25(OH)D3of Han-zu significantly higher than She-zu,especially women between the 40-59 age and men between the 50- 69 age,there is a positive correlation (P< 0. 05). BGP of She-zu is higher than Han-zu, especially men between the 40 -69 age (P < 0. 05). The E2 indicators of Han male were higher than She-zu male, especially 40-59 age group (P <0. 05). P1NP of Han-zu is higher than She-zu, especially men at 50-59 age, 80 above groups, women above 50 age groups(P <0.05). The Pearson correlation analysis showed BMD were positive correlation with E2, 25(OH)D3, T,and negative correlation with PTH、BGP、PINP. Conclusions The study of 25 (OH)D3, BGP, P1NP, E2 can be used as the Han-zu、She-zu healthy people for early detection of targets, 25( OH)D3 levels of She-zu generally was low, may be related to their lifestyle or vitamin D gene, deserves further study. BMD have significant positive correlation with 25(OH)D3, E2,T. No negative correlation with PTH, PINP, BCG, and no significant correlation with ALP. |
