浙江东部沿海地区中老年人群腰椎骨密度调查研究

Investigation on normal values of lumbar vertebra bone mineral density measured with pDEXA in elderly people of Zhejiang coast area

目的通过对浙江沿海地区中老年本地人群腰椎骨密度(BMD)资料的调查,对资料的分布特点进行分析。方法采用美国GE公司的双能X线骨密度仪,对浙江沿海地区的本地籍中老年人群进行BMD检查。结果从50岁以后开始BMD值和T值逐渐降低,女性降幅和患病率明显高于男性(P<0.05)。BMD值和T值与年龄呈显著负相关(P<0.05),女性相关性更强。结论中老年人群随着年龄增长,骨密度逐渐降低,骨质疏松患病率明显增加,女性更为明显,骨密度差异与地域、生活习性有相关性。

Objective To analyze the normal values of lumbar vertebra bone mineral density （BMD） measured with pDEXA in elderly people of Zhejiang coast area. Methods pDEXA 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. The general da- ta,height,weight,habit of living and diet, case history,history of menstruation, pregnancy,maternity and lactation were recorded. Results Among people aged over 50,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 showed 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 is increasing while BMD is decreasing and the morbidity of osteoporosis is increasing, especially in women. Bone mineral density differences have correlation with regions and life habits.
