379例绝经前后妇女骨密度调查与身高的关系

379 cases of bone mineral density in postmenopausal women before and after the investigation and the relationship between height

目的了解妇女身高体重与体内骨含量的关系。方法采用米尺和磅秤测量身高和体重及双能X线骨密度仪测骨密度值和超声骨密度仪测左侧跟骨的SOS、STI、LBM。结果不同年龄组身高、体重及体块指数与超声速度、骨硬度指数、低骨量及骨密度值存在着统计学差异,随着年龄的增长SOS及STI呈现出下降趋势,其峰值在40岁之前;而低骨量LBM、骨质疏松发生率也明显增高。身高与SOS、STI、LBM呈正相关,与骨密度值无关;体重与STI、LBM、骨密度值呈正相关,与SOS值无关,BMI与SOS、STI呈负相关,与LBM、骨密度呈正相关。结论女性47岁后骨密度数据从"正常范围"转入低骨量,70岁后骨质疏松者明显增多,具有高度骨折风险。

Objective Understand the women height weight and body bone content relationship. Methods Using meter rule and scales measuring height and weight and double X-ray absorptiometry measured op value and ultrasonic bone density instrumental measuring left ealcaneal of SOS, STI, LBM. Results Different age groups height, weight and body mass index and ultrasonic velocity, bone hardness index, low bone mass and osteoporosis values exist statistically significant, as the growth of the age, SOS and STI showed a trend of decline its peak in 40 years old before;And low bone mass LBM, osteoporosis op significantly higher rate. Height and SOS, STI, LBM was positively correlated, Op value is irrelevant; Weight and STI, LBM, Op value was positively correlated, SOS value is irrelevant, BMI and SOS, STI was negatively correlated, Op were positively correlated. Conclusion Bone mineral density in women after the age of 47, data from the ＂normal range＂ into the low bone mass, osteoporosis after the age of 70 were significantly increased, with a high risk of fracture.
