한국여성의 연령별 골밀도 -대구지역을 중심으로

Abstract

The aim of this study was to assess the change of bone mineral density (BMD) in Korean women in Taegu. Subjects were 242 healthy female in the range of 7~67 years old, were divided into 12 age groups in order lo assess the BMD according to age. BMD measurements of lumbar spine, femur(neck, ward’s triangle, trochanter) and total body were performed by dual energy X-ray absorptiometry(DEXA). The period of peak bone mass was 30~34 years in lumbar spine, 25~29 years in femoral neck and ward's triangle, 20~24 years in trochanter, 45~49 years in total body. Age-related decline in BMD was accclcrated from ages 50 to 59 yr, and then decelerated somewhat after age 59 yr. Yearly percentage BMD reduction on the basis of peak BMD was 0.90% in lumbar spine, 0.70% in femoral ncck, 0.99% in ward's triangle. 0.57% in trochanter, 1.01% in total body, respectively. When the fracturc threshold of Riggs et a is applied to our study, the age that the mean BMD of lumbar spine came to the fracture threshold was 55~59 years old.
