Prevalence of Osteoporosis of Korean Women based on Bone Mineral Density of the radius and effect of menopause on osteoporosis / 대한산부인과학회잡지

ABSTRACT

OBJECTIVE: To determine the prevalence of osteoporosis based on the measurement of bone mineral density (BMD) and to examine the effect of menopausal status on BMD in Korean women. METHODS: Ultra-distal and distal radius BMD was measured by dual energy X ray absorptiometry (osteoplan p-DXA) in 296 women. The result was analysed, retrospectively. We diagnosed osteopenia and osteoporosis according to the WHO criteria. RESULTS: The ultra-distal and distal radius BMD and T score decreased significantly with increase of age. Of women in their thirties, the prevalence of ultra-distal and distal radial osteoporosis were 0%, 6.2%, and in their forties, they were 7.6%, 3.4% and in their fifties, they were 26.6%, 27.9% and of women in their sixties, they were 81.7%, 87.8%. Of women in their forties and fifties, premenopausal women had a higher BMD result than postmenopausal women in the same age group. Of premenopausal women in their forties, the prevalence of osteoporosis were 4.6%, 2.3% and of postmenopausal women in that age, they were 15.6%, 6.3%. Of premenopausal women in their fifties, the prevalence of osteoporosis were 8.3%, 8.3% and of postmenopausal women in that age, they were 29.9%, 31.3%. CONCLUSION: With increasing age, the prevalence of osteoporosis increased and the BMD decreased. In the postmenopausal state, this difference became larger.
