摘　　要：目的探讨济南市中老年人骨质疏松的患病情况，为老年病工作者和老年人群的骨保健提供资料。方法对1116例中老年人健康查体者应用单能X线骨密度仪测量的右跟骨骨密度资料进行了回顾性分析，比较了骨密度与年龄和性别的关系。结果①在男性和女性45岁以上的人群中，随着年龄的增大，T值和BMD均逐渐降低，女性的降低幅度明显高于男性（P〈0．05）。②骨量减少和骨质疏松者在60岁以上男性中占60％，75岁以上占70％；骨质疏松患病率男性65岁～69岁组约占5％，70岁～74岁组约占10％，大于75岁组在20％以上。45岁～49岁的女性有30％的骨量减少；骨量减少和骨质疏松在女性50岁～54岁约占45％，55岁～59岁约占80％，60岁～69岁约占90％，70岁以上者高达99％。骨质疏松患病率在女性50岁～54岁近10％，55岁～59岁近30％，60岁～64岁近40％，65岁～69岁50％以上，70岁以上在70％以上。女性的骨质疏松患病率明显高于男性（P〈0．01）。③骨密度测定结果与年龄的相关性分析也显示，T值和BMD与年龄呈显著的负相关（P〈0．05），在女性其相关性更强。④以年龄为自变量，以T值和BMD为应变量，进行曲线拟合也看出，无论在男性还是在女性，T值和BMD随年龄的增大而逐渐变小，在女性曲线更陡。结论在中老年人群，随着年龄的增大，骨密度逐渐降低，骨质疏松的患病率明显增加，尤其在女性更为明显。Objective To analyze the reality about bone mineral density（BMD） in middle-age and old people in Jinan in order to provide information on bone health for doctors and the elderly. Methods Single X-ray Absorptiometry（SXA） was used to determine the bone mineral density in 1116 middle-aged and old people. Through analysis of these documents to find the relation among BMD with age and gender. Results ① Among people aged over 45, T and BMD were decreasing while age was increasing. The decreasing rate was significant higher in women than in men（ P 〈 0.05）. ②In men, 60 percent was osteopenia or osteoporosis in group aged over 60, 70 percent in group older than 75; the morbidity of osteoporosis in 65 - 69 group was 5 percent, 10 percent in 70 - 74 group, more than 20 percent in group older than 75. In women, 30 percent people had osteopenia in 45 - 49 group, 45 percent had osteopenia or osteoporosis in 50 - 54 group, 80 percent in 55 - 59 group, 90 percent in 60- 69 group,99 percent in group aged over 70 group. In women, the morbidity of osteoporosis was about 10 percent in 50 - 54 group, about 30 percent in 55 - 59 group, almost 40 percent in 60 - 64 group, more than 50 percent in 65 - 69 group, more than 70 percent in group older than 70. The morbidity of osteoporosis was significant higher in women than in men（ P 〈 0.01 ） . ③The correlation analysis shows that there was negative correlation between BMD with T and age（ P 〈 0.05）, especially in women. ④We did curve fitting with age as independent variable and BMD and T as dependent variable, whether in men or in women, we could see T and BMD were decreasing while age was increasing, but the curve was steeper 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.
