高强度体力劳动者跟骨定量超声测定结果的分析研究

目的 测定高强度体力劳动者(建筑工人)和脑力劳动者(中学教师)跟骨定量超声参数,分析评价体力劳动强度对骨量变化的影响。方法 采用UBIS3000型定量超声仪,对兰州市区217名建筑工人和183名中学教师(男,年龄20-49岁)跟骨定量超声参数进行测定。结果 建筑工人跟骨超声振幅衰减(BUA)和刚度(STT)在20-49岁呈递增趋势,超声声速(SOS)递减,但无统计学差异。教师的三项数据峰值都在30-39岁,各年龄组均低于建筑工人组。结论 跟骨三项指标随年龄增长改变,体力劳动的强度对骨量变化有重要影响,强体力劳动者骨质量优于脑力劳动者,提示运动有助于保持骨量,预防骨质疏松的发生。

Calcaneal quantitative ultrasound measurement in high-strength physical laborers

Objective To measure calcaneal quantitative parameters of high-strength physical workers (building workers) and mental workers (middle-school teachers), and analyze the influence of physical labor strength on change of bone mass. Methods UBIS 3000 quantitative ultrasound ( QUS) was used to measure cal-caneal quantitative ultrasonic parameters in 217 building workers and 183 middle-school teachers (male, 20-49 years old). Results BUA of building workers decreased and STI of building workers aged 20-49 years increased pro-gressively , and there were no statistical differences in SOS which decreased progressively. The peaks of three data (BUA,STI,SOS)in the teachers appeared at age of 30-39 years;and the three data of each age group were lower than those of building workers. Conclusions The three indexes change with the increase of age; the strength of physical labor influences the change of bone mass greatly;and the bone qualities of high-strength physical workers are superior to those of normal people. It is suggested that physical exercises help to preserve bone mass and prevent osteoporosis.
