中国福建莆田地区畲族居民742例骨密度流行病学调查

Investigation of bone mineral density in 742 in Putian of the Chinese She-zhu

目的调查莆田地区全国人口较少的畲族居民骨密度,为诊断治疗预防骨质疏松症而建立骨密度正常参考值的数据提供资料。方法采用美国Osteometer MediTech公司的DTX-200骨密度仪对莆田地区的本地畲族居民人群742人(男251,女491)进行前臂挠尺骨远端的BMD检查,用SPSS10.0分析软件进行统计学处理,按年龄组进行平均值标准差的计数,各中老年龄组骨量与峰值骨量组比较,观察其变化规律。结果莆田地区畲族居民人群男性女性骨密度峰值(PBM)均出现在30～39岁,随后成下降趋势,同年龄段和同一测量部位的男性BMD均高于女性,女性在50岁以后,男性在70岁以后骨密度值明显下降。结论莆田地区畲族居民骨质疏松发生率和增龄呈明显正相关,女性在50岁以后,男性在70岁以后,骨质疏松发生率明显增高,应及早预防。

Objective To investigate the bone mineral density（BMD） in the population in Putian district of the Chinese She-zhu and provide the basis for prevention,diagnosis and treatment of osteoporosis. Methods The measurement of BMD of ulna and radius to distal forearm on 742 in Putian district of the She-zhu, including 251 men and 491 women, were conducted with DTX-200 bone densitometer produced by the American Osteometer MediTech Company. The mean of BMD were analyzed using SPSS10.0. The mean values and standard deviations of the data of measurement were calculated by age groups. Results The peak BMD （PBM） lie in the age group of 30-39 years for both men and women. The PBM of radius and ulna in men were 0.62 ±0. 05, those in women were 0.55 ± 0. 08,while BMD decreases gradually after 40 years. The bone loss rate and prevalence of osteoporosis increased of the 50 years in women and 70 in men. Conclusions The prevalence of osteoporosis in Putian District of the She-zhu increases with age,especially after 50 years old in women and 70 years old in men.
