壮族健康女性跟骨定量超声骨量峰值研究

目的]建立壮族女性定量超声骨量峰值,为广西壮族人群骨质疏松症的诊断和防治效果的评估提供依据。方法]采用定量超声法对25～70岁祖辈三代双亲均为壮族的746例健康女性志愿者进行跟骨定量超声测定,以5岁为一个年龄组。结果]峰值骨量出现在35岁～组,BUA峰值为(64.83±3.78)db/MHz。在25～34岁年龄范围内BUA值随年龄增大而增大,40岁～略有下降,但仍处较高水平,45岁～后随年龄增长跟骨BUA值逐渐下降。50岁～组至65～70岁组骨量正常百分比由58.87%降低至7.08%。结论]建立了壮族女性定量超声骨量峰值,提供了该地区定量超声的BUA参考值和骨质疏松症诊断的科学依据。

STUDY ON THE PEAK BONE MASS BY CALCANEAL QUANTITATIVE ULTRASOUND IN ZHUANG HEALTHY WOMEN

Objective]To establish quantitative ultrasound Zhuang female peak bone mass,and to provide Guangxi Zhuang population reference value of osteoporosis diagnosis and the basis for the assessment of control effectiveness.Methods]Zhuang 746 healthy female volunteers(25 to 70 years)were randomly selected.Quantitative ultrasound of the calcaneus on bone mass in these women were determined.Every 5 years were as an age group.Results]Peak bone mass appeared in the 35-year-old group,and the peak BUA was 64.83 ± 3.78(db/MHz).Calcaneal BUA values of 25 to 34 year age range increased with age,40-years old decreased slightly,but still at a high level,and gradually decreased with increasing age of above 45-years.The percentage of normal bone mass of 50-age group and 65 to 70 age group decreased from 58.87% to 7.08%.Conclusion]Zhuang female peak bone mass by quantitative ultrasound was established,test results provided a reference values of BUA for women,and provide a scientific basis for diagnostic criteria for osteoporosis.
