Abstract |
Background Osteoporosis is defined based on T-scores (<-2.5), which are calculated from mean value and standard deviation (SD) of bone mineral density (BMD) of young adults. Therefore the diagnosis of osteoporosis is race and population specific. We investigated new reference young population and establish the prevalence of osteoporosis.
Methods 3,435 males and 10,231 females are enrolled for this study, from 2003 to 2004. There BMD were taken at health promotion center, Ajou university hospital, Suwon, Korea by Dual energy X-ray Absorptiometry. Osteoporosis is defined by T-score less than -2.5 SD of 20~29 years old young adults in men. In women, T-score less than -2.5 SD of 30~39 years old adults.
Results In men, osteoporosis prevalence is twelve percent by previous reference value, but, eight percent by new reference value. In women, osteoporosis prevalence is twelve percent by previous reference value and eleven percent by new reference value.
Conclusion This result showed that different reference values leads to different prevalence of osteoporosis. So, for the accurate diagnosis of osteoporosis, reference populations of young adults depend on each machines should be representative of the population of each country. |
