Comparison of the BMD between the lumbar spine and the hip in middle-aged and elder people in Chongqing / 重庆医学

ABSTRACT

Objective To explore the difference between the diagnosis of osteoporosis based on the measured value of lumbar spine and hip bone mineral density in middle-aged and elder people in Chongqing .Methods Dual energy X-ray absorptiometry was used to measure of lumbar spine and hip bone mineral density to people over the age of 40 in 2 151 cases ,grouped according to age and gender .Results Both male and female lumbar spine and hip bone mineral density values decreased gradually with increasing age;the detection rate of osteoporosis of the male′s hip was higher than that of the lumbar spine among each age group ,which was of statistical significance(P<0 .05);the detection rate of osteoporosis of the female′s lumbar spine was higher than that of the hip among each age group ,which was of statistical significance (P<0 .05) .Conclusion As for elderly male ,the sensitive position for osteoporosis detection is the hip .However ,as for elderly female is the lumbar spine .In order to improve the detection rate of osteo-porosis ,joint detection of both two positions is well suggested .
