Evaluation of Osteoporosis by Quantitative Ultrasound in Community Health Nursing for Screen
摘要
The purposes of this study were to understand and compare the precision and accuracy of quantitative ultrasound (QUS) with dual-energy x-ray absorptiometry (DEXA). First, the study was conducted from April 14, 2001 and ended on March 26, 2002, for internal machine quality assurance. Second, a total 60 healthy female workers participated in the random variation of two QUS tests. Third, 50 female members of a community fitness club took the QUS and DEXA of the lumbar spine. There were 30 results in the quality assurance test with a stable degree of stable instrument precision Variations of the two QUS tests for calcaneus were lower. The mean and stander deviation were -0.85±4.72, the 95% confidence interval was -2.07~0.37, pare T test were -1.40 p=0.17, Spearman's correlation=0.975 p＜0.01. The correlation QUS and DEXA of lumbar spine were 0.521 p＜0.01, which shows the validity of QUS is acceptable for community screening of lower bone density.
