本文介绍了骨矿物质水平在股骨近端的美国成年人的基础上，全国代表性的样本7116名男性和女性年龄在20岁及以上。数据收集于第三次全国健康与营养检查调查（NHANES III，1988-1991）的第1阶段，采用双能X射线吸收测定法，包括骨矿物质密度（EMD）、骨矿物质含量（BMC）和股骨近端5个选定感兴趣区域（ROI）扫描的骨面积：股骨颈、转子、转子间、沃德三角和总骨密度。按年龄和性别分别提供非西班牙裔白人（NHW）、非西班牙裔黑人（NHB）和墨西哥裔美国人（MA）的这些变量。五个ROI的BMD和BMC随年龄增长而下降，而面积则没有下降。骨密度和骨矿物质含量NHB最高，MA居中，NHW最低，而面积NHW最高，NHB居中，MA最低。在所有三个种族/民族组中，男性的BMD、BMC和面积均大于女性。年龄、性别或人种/种族的差异在Ward三角区最大，其次是股骨颈;转子、转子间和总ROI的模式彼此相当相似。本报告提供了有关成人股骨骨矿物质水平的广泛数据，这些数据来自迄今为止最大的样本之一，应作为其他研究成人骨骼部位的参考数据。
This paper describes bone mineral levels in the proximal femur of US adults based on a nationally representative sample of 7116 men and women aged 20 years and older. The data were collected in phase 1 of the third National Health and Nutrition Examination Survey (NHANES III, 1988-1991) using dual-energy X-ray absorptiometry, and included bone mineral density (EMD), bone mineral content (BMC) and area of bone scanned in five selected regions of interest (ROI) in the proximal femur: femur neck, trochanter, intertrochanter, Ward's triangle and total. These variables are provided separately by age and sex for non-Hispanic whites (NHW), non-Hispanic blacks (NHB) and Mexican Americans (MA). BMD and BMC in the five ROI tended to decline with age, whereas area did not. BMD and BMC were highest in NHB, intermediate in MA and lowest in NHW, but areas were highest in NHW, intermediate in NHB and lowest in MA. Men had greater BMD, BMC and area than women in all three race/ethnic groups. Differences by age, sex or race/ethnicity tended to be the largest in Ward's triangle, followed by the femur neck; patterns in the trochanter, intertrochanter and total ROI were reasonably similar to each other. This report provides extensive data on femur bone mineral levels of adults from one of the largest samples available to date and should be valuable as reference data for other studies which examine this skeletal site in adults.
