内蒙古满洲里和北京地区部分人群骨密度调查分析

 目的 了解内蒙古满洲里地区和北京地区部分人群的骨密度情况,探究其生活的人文地理条件对骨密度的影响.方法 对20名男性和30名女性满洲里50～60岁人群进行双光能X线骨密度测量,并分别与北京地区同一年龄段男女性部分人员进行对比分析.结果 内蒙古满洲里地区50～60岁人群与北京地区相比较;不论男性还是女性,其腰椎L2～4、股骨颈、Ward区、大转子的峰值均数均有统计学差别.结论 内蒙古满洲里地区50～60岁人群峰值骨量低于北京地区同年龄段人群,可能原因是该地区饮用水含氟量超标.

Investigation and analysis of bone density of populations in Manzhouli of Inner Mongolia and in Beijing

Objective To find out about the bone density of populations in Manzhouli, Inner Mongolia, and in Beijing, and to study the living conditions there. Methods The bone density of two groups consisting of 20 males and 30 females, aged 50 to 60, in Manzhouli and Beijing, respeetively, were measured using dual - optical energy X - Rays, and the mean crest value of bone densily between these two populations was compared and analyzed. Results There was significant difference in the mean crest value of lumbar spines L2-4 , collum femoris, Ward＇s area and trochiter. Conclusion The high fluorine content in drinking water in Manzhouli, Inner Mongolia, may be the main reason for the low crest value of bone density for the local population.
