Abstract
Repeated measurements of bone mineral content can indicate the rate of bone loss among postmenopausal women. The clinical utility of such loss rate measurements will depend upon the long-term precision of the measurements. We have analyzed the precision of appendicular bone measurements among 495 Japanese-Americans followed for an average of 5.3 years and of both appendicular and axial measurements among 70 clinical trial participants followed for 2 years. Tables were derived from these analyses to quantitate the precision of individual loss rates under varying measurement conditions that might be encountered in clinical practice. The results demonstrate that only unusually rapid loss rates could be identified with confidence within short intervals, such as 1 year or 2. Extending the length of follow-up, however, appreciably improved the measured loss rate precision. In comparisons between bone sites, appendicular sites were determined to achieve a specified precision within the shortest intervals, followed by spine dual photon absorptiometry measurements. Spine quantitative computerized tomography measurements and measurements of hip sites required considerably longer follow-up intervals to achieve comparable precision.
