132例原发性骨质疏松症女性身高变化与腰椎骨密度相关性分析

Correlation analysis between height change and bone mineral density of the lumbar vertebrae in 132 women with primary osteoporosis

目的分析骨质疏松症女性患者身高变化与腰椎骨密度的相关性。方法通过测量132例女性骨质疏松症患者的现身高，回顾25-30岁时身高，计算身高变矮程度，同时检测患者的BMD进行相关性分析，并描绘散点图。结果随着患者腰椎骨密度降低，患者较年轻时身高变矮的程度在逐渐增加；随着年龄的增加，患者的身高逐渐变矮，采用SPSSll．5Spearman相关系数的方法计算，得出P〉0．05，不具有统计学差异，即本组研究中选取的132例患者的身高变化与患者腰椎1-4的BMD之间无相关联性。结论天津地区132例女性骨质疏松症患者的身高变化与腰椎BMD之间无明显相关性。人体身高变化的影响因素较多，同时存在测量的误差，在观察身高与BMD相关性分析时应分别测量躯干或肢体的长度，以提高准确性。

Objective To analyze the correlation between height change and bone mineral density of the lumbar vertebrae in women with primary osteoporosis. Methods One hundred and thirty-two women with osteoporosis were selected. The present height of all the patients was measured. The changes of height were calculated by comparing with their height at 25-30 years old. Meanwhile, the bone mineral density （BMD） was detected for correlation analysis, and the scatter diagram was also depicted. Results Along with the decrease of BMD of the lumbar vertebrae, the decrease of the height accumulated compared with the height when they were young. And along with the increase of age, their height shortened gradually. But by adopting the method of SPSS11.5 Spearman correlation coefficient, a P 〉 0. 05 was observed, showing no significant difference, which also indicated there was no signifianct correlation between the height change and BMD of the lumbar vertebrae in 132 women with osteoporosis in this study. Conclusion There is no signifianct correlation between the height change and BMD of the lumbar vertebrae in 132 women with osteoporosis in Tianjin. There are various factors affecting the change of human height, and the measurement error also exists at the same time. So, a respective measurement of the length of the trunk or the limbs should be performed when analyzing the correlation between height and BMD, in order to improve the accuracy.
