Abstract

Bone mineral density (BMD) of the lumbar spine and hip was studied in 1,047 women visiting the menopause clinic, to assess the correlation of BMD among various measurement sites. Bone mass measurement was performed utilizing dual energy X-ray absorptiometer (DEXA), Hologic QDR 2000. The results revealed a significantly high correlation of BMD of total hip and spine. (r = 0.7021, P < 0.001) Nevertheless, BMD of the spine was mostly correlated with BMD of trochanteric site (r = 0.7235, P < 0.001) and least correlated with BMD of intertrochanteric region. (r = 0.2426, P < 0.001) In conclusion, BMD of spine and hip is highly correlated. However, there was some heterogeneity of correlation in different specific measurement sites.

摘要

对1047名前往更年期诊所就诊的女性的腰椎和髋部骨密度（BMD）进行了研究，以评估不同测量部位之间骨密度的相关性。使用双能X线吸收仪（DEXA）Hologic QDR 2000进行骨量测量。结果显示，全髋和脊柱的骨密度存在显著的高度相关性（r = 0.7021，P < 0.001）。然而，脊柱的骨密度与转子部位的骨密度相关性最高（r = 0.7235，P < 0.001），与转子间区域的骨密度相关性最低（r = 0.2426，P < 0.001）。总之，脊柱和髋部的骨密度高度相关。然而，在不同的特定测量部位，相关性存在一些异质性。
