资阳地区定量超声跟骨骨量测定的流调分析

目的调查四川资阳地区健康人群骨密度值及骨质疏松患病率,为骨质疏松的诊断和防治提供科学依据。方法对资阳地区人群亚群抽样1976例,应用日本FURUNO公司生产的超声骨量测定仪CM100测试受试者的右跟骨的超声速度(SOS)值。结果男女骨量峰值(PBM)均出现在20～39岁组,随年龄增加骨量逐渐下降。女性50岁以后骨量丢失明显加快,60～69岁年龄组骨量丢失最快;男性70岁以后骨量丢失明显加快。80岁以前各年龄组女性骨量丢失明显高于男性,80岁以后男性骨量丢失高于女性,但累计骨量丢失女性仍明显高于男性。结论骨量随年龄增长而下降,骨质疏松发病率也随之增加。女性骨量丢失明显高于男性,女性骨质疏松发病率也明显高于男性。

Investigation of bone mineral density in healthy population in Ziyang Province by quantitative ultrasonography in calcaneal

Objective To investigate the bone mineral density (BMD) and the incidence of osteoporosis (OP) in healthy population in Sichuan Ziyang Province of China, and to provide scientific data for diagonsis and treatment of osteoporosis. Methods Totally,1976 people were randomly selected from healthy adults in Ziyang Province.The BMD of calcaneal was measured by Quantitative ultrasound. Results The peak bone mass (PBM) of both male and female were in the age group of 20-39.And the bone mass was gradually declined with the increasing age.The bone loss in females was faster after 50 years old.In the age groups of 60-69,the bone loss was the fastest.The bone loss in males was faster after 70 years old. Faster bone loss was found in females than males before the age of 80,and the contrary was seen after 80 years old.The prevalence of OP of females was higher than that of males. Conclusions BMD decreases with age and the incidence of osteoporosis increases with age.Both the bone loss and the incidence of OP of females are higher than that of males.
