[目的]对体检中筛查出的椎体骨量减少、骨质疏松症患者,分析其发生率与年龄、性别的关系。[方法]使用定量CT(QCT)对575例体检者进行腰椎骨密度检测并分析。研究数据使用SAS 9.0进行统计分析。[结果]40岁以后椎体骨矿物含量(BMD)随年龄增高而下降。本组骨质疏松症发生率,女性:50~59岁以上56.34%,60~69岁以上87.80%,70~79岁以上97.22%,80~89岁以上100%;男性:50~59岁以上25.44%,60~69岁以上50.64%,70~79岁以上66.66%,80~89岁以上90.91%。[结论]骨质疏松症发生率与年龄增加有关,年龄越大,骨质疏松症发生率越高。女性显著高于男性。
[Objective] To analyze the relationship between the incidence and the age and gender in the patients with osteopenia and osteoporosis who were screened in physical examination. [Methods] Quantitative CT (QCT) was used to detect and analyze lumbar spine bone mineral density in 575 subjects. Study Data SAS 9.0 was used for statistical analysis. [Result] The vertebral bone mineral content (BMD) after 40 years old decreased with age. The incidence of osteoporosis in this group, women: 56.34% over the age of 50 to 59, 87.80% over the age of 60 to 69, 97.22% over the age of 70 to 79, 100% over 80 to 89 years old; men: 50 to 59 years old 25.44%, 50.64% above 60-69, 66.66% above 70-79 and 90.91% above 80-89. [Conclusion] The incidence of osteoporosis is related to the increase of age. The older the higher the incidence of osteoporosis. Women were significantly higher than men.
