目的 探讨呼和浩特地区中老年人骨质疏松的患病情况,为呼和浩特地区老年病的防治和老年人群的骨保健提供资料.方法 采用美国GE公司生产的LUNAR-Bravo双能X线骨密度仪对呼和浩特地区500对汉族中老年夫妇进行骨密度测定.结果 从45岁以后开始男性和女性随着年龄的增长,BMD值和T值逐渐降低,女性降低幅度明显高于男性（P〈0.05）.女性在55岁以后可见明显的骨量丢失加速,男性是缓慢的.女性的患病率明显高于男性（P〈0.05）.骨密度测定结果与年龄的相关性分析显示,BMD值和T值与年龄呈显著的负相关（P〈0.05）,女性相关性更强.结论 呼和浩特地区汉族中老年人群随着年龄的增长,骨密度逐渐降低,骨质疏松患病率明显增加,女性更为明显,但比广州、上海、长沙、成都等地区报道骨质疏松发生的年龄推迟,这与呼和浩特地区特殊的地理环境和饮食习惯、饮食营养呈正相关.

Objective To analyze the reality about bone mineral density（BMD） in middle-age and old people in Huhehaote in order to provide information on bone health for doctors and the elderly. Methods DPA was used to determine the bone mineral density in middle-aged and old people. Through analysis of these documents to find the relation among BMD with age and gender. Results Among people aged over 45, T and BMD were decreasing while age was increasing. The decreasing rate was significantly higher in women than in men （ P 〈 0. 05 ）. The morbidity of osteoporosis was significantly higher in women than in men（ P 〈 0. 01 ）. The correlation analysis shows that there was negative correlation between BMD with T and age（ P 〈 0.05）, especially in women. Conclusion In middle-aged and old people, age was increasing while BMD was decreasing and the morbidity of osteoporosis was increasing, especially in women, but its report of osteoporosis age deferred than Guangzhou Shanghai Changsha Chengdu. This problem becomes direct rations of special environment and dietetical tratidion.
