重庆市1424例健康体检者超声桡骨骨密度检测结果分析

Analysis of bone mineral density of the radius in 1424 healthy people in Chongqing

目的了解位于西南地区的重庆市健康成年男性、女性的骨密度现状,为骨质疏松症的筛查、预防提供科学依据。方法采用Sunlight Omnissense TM 7000超声骨密度仪,调查测量了自2012年9月～2013年1月期间在西南大学体检中心参加健康体检的1424（女性643,男性781）名汉族成年人桡骨远端骨密度,根据T值判定骨量减少和骨质疏松,并计算其检出率。结果女性骨量减少248例,检出率为38.57%,骨质疏松187例,检出率为29.08%;男性骨量减少339例,检出率为43.41%,骨质疏松96例,检出率为12.29%。重庆地区骨量减少和骨质疏松的检出率与贵阳、广州、北京地区比较男性在20岁段～40岁段均有显著差异（P〈0.001）,与杭州地区相比男性在20岁段、30岁段、60岁段、70岁段有显著差异（P〈0.001）,与沈阳地区相比男性在20岁段、50岁段、60岁段均有差异（P〈0.05）;与贵阳地区比较女性在50岁段和70岁段有显著差异（P〈0.001）,与广州地区相比女性在20岁段、40岁段、60岁段、70岁段均有显著差异（P〈0.001）,与杭州、沈阳地区相比女性在50岁段和60岁段有显著差异（P〈0.001）,与北京地区相比女性在20岁段～50岁段有显著差异（P〈0.001）。结论重庆地区男女性在50岁以前T值水平相当并保持相对稳定,50岁以后女性T值明显低于男性;随年龄增加男女性T值均逐渐下降,女性在围绝经期下降迅速。重庆地区在骨量减少及骨质疏松的检出率上较我国其他地区处于中等水平。

Objective To investigate bone mineral density（ BMD） of healthy men and women in Chongqing,and to provide scientific evidence for the screening and prevention of osteoporosis（ OP）. Methods BMD of 1424 Han people,who received health examination in the Health Examination Center of Southwest China University from September 2012 to January 2013,was tested using ultrasound absorptiometry（ Sunlight Omnissense TM7000）. Osteopenia or OP was judged according to the T-value.The detection rate was calculated respectively. Re sults The number of osteopenia and OP was 248（ 38. 57%） and 187（ 29. 08%）,respectively,in women,and 339（ 43. 41%） and 96（ 12. 29%）,respectively,in men. The detection rates of osteopenia and OP in 20- 40- year-old men in Chongqing were significantly different compared to those in Guiyang,Guangzhou,and Beijing（ P〈0. 001）. The detection rates in 20,30,60,and 70 years old men in Chongqing were significantly different compared to those in Hangzhou（ P〈0. 001）,and in 20,50,and 60 years old men were significantly different compared to those in Chongqing and Shenyang（ P〈0. 001）. In women,the detection rates were significantly different compared to those in 50 and 70 years old women in Guiyang（ P〈0. 001）,in 20,40,60,and 70 years old women in Guangzhou（ P〈0. 001）,in 50 and 60 years old women in Hangzhou and Shenyang（ P〈0. 001）,and in 20- 50- year-old women in Beijing（ P〈0. 001）. Conclusion The T-value of both genders is stable before 50 years old in Chongqing. The T-value in women is lower than that in man after 50 years old. The T-value in women and men gradually decreases along with the increase of age. The T-value in women decreases more rapidly during perimenopause period. Comparing to those in other cities,the detection rates of osteopenia and OP in Chongqing is at the middle level in china.
