Analysis of lumbar bone mineral density of 575 individuals by QCT examination / 中国矫形外科杂志

ABSTRACT

[Objective]To analyze the relation of age and sex with the incidence of physical examinees with osteoporosis and low bone mass of vertebras.[Method]Quantitative CT(QCT) was used to examine and analyze the lumbar bone mineral density in 575 physical examinees.The data was analyzed by statistical software SAS 9.0.[Result]Bone mineral density(BMD)decreased with age after 50 years old.The occurrence rates of osteoporosis were 56.34% for females at 50-59 years,87.80% at 60-69 years,97.22% at 70-79 years and 100% at 80-89 years,25.44% for males at 50-59 years,50.64% at 60-69 years,66.66% at 70-79 years,and 90.91% at 80-89 years.[Conclusion]The incidence of osteoporosis is positively related with the age.The occurrence rate of osteoporosis increases with increasing age.It is obviously higher in females than in males.
