Summary

The osteoporosis-profile test for predicting bone loss in women is unreliable. Diet variations caused significant fluctuations, rendering the test useless for individual assessment.

Area of Science:

  • Endocrinology
  • Bone Metabolism
  • Clinical Diagnostics

Context:

  • The osteoporosis-profile, a diagnostic tool estimating future bone loss, is gaining traction among Danish physicians.
  • It utilizes serum osteocalcin, alkaline phosphatases, and urinary calcium/hydroxyproline excretions to assess bone formation and resorption.
  • The test is particularly aimed at peri- and postmenopausal women.

Purpose:

  • To evaluate the clinical utility and reliability of the osteoporosis-profile test.
  • To determine if dietary changes impact the accuracy of bone loss estimations.
  • To assess the test's validity for individual patient diagnosis.

Summary:

  • The osteoporosis-profile was administered to six women aged 46-56 over three weekends with varying diets.
  • Each weekend concluded with a collagen-free meal and overnight fast to standardize the testing conditions.
  • Observed individual variations in estimated bone loss reached 200-300% due to dietary influences.

Impact:

  • The study demonstrates that the osteoporosis-profile is not a reliable indicator of bone loss in individuals.
  • Dietary modifications significantly affect the test's results, compromising its diagnostic value.
  • The findings question the widespread clinical application of this specific osteoporosis assessment tool.
