Hypothesis

There is considerable discrepancy in the diagnosis of osteoporosis between reference data derived from the local population and reference data provided by densitometers.

Conclusion

The T-scores provided by the Hologic QDR4500 over-diagnosed osteoporosis in Vietnamese men and women.

Supporting Evidence

  • The prevalence of osteoporosis was found to be 29% in post-menopausal women using local T-scores.
  • Using the densitometer's T-scores, the prevalence of osteoporosis in women was 44%.
  • In men aged 50+, the prevalence of osteoporosis was 10% based on local T-scores compared to 30% using the densitometer's T-scores.

Takeaway

This study looked at how bone density affects the diagnosis of osteoporosis in Vietnamese people, finding that many were wrongly diagnosed.

Methodology

A cross-sectional study measuring bone mineral density in 357 men and 870 women using DXA.

Potential Biases

Potential bias due to exclusion of individuals with diseases affecting bone metabolism.

Limitations

The study's findings may not be generalizable to rural populations and could underestimate the prevalence of osteoporosis.

Participant Demographics

Participants included 357 men and 870 women aged 18 to 89 years, with 58.5% of men and 51% of women aged 50 or older.
