为了评估澳大利亚女性不同部位的骨质疏松症患病率，成年女性的横断面骨密度(BMD)数据来自随机抽取的按年龄分层的人群样本(n=1494；20-94年)，该样本来自澳大利亚特有的人口巴旺统计部。使用回归技术得出腰椎、股骨近端、前臂和全身骨密度的年龄和体重(以及三个部位的身高)匹配的参考范围。根据世界卫生组织(WHO)的指南，PA脊柱骨质疏松的截止值为0.917 g/cm(2)，股骨颈为0.713 g/cm(2)。骨量减少的上限水平在PA脊柱为1.128 g/cm(2)，在股骨颈为0.913 g/cm(2)。澳大利亚女性被归类为PA脊柱、股骨颈或前臂中部骨质疏松的比例从40-44岁的0.9%到79岁以上的87.0%不等。这项研究提供了代表澳大利亚女性人口的参考数据。根据世界卫生组织的指南，澳大利亚老年妇女中有很大一部分患有骨质疏松症。
To evaluate the prevalence of osteoporosis at various sites among Australian women, cross-sectional bone mineral density (BMD) data for adult females was obtained from an age-stratified population-based sample (n = 1494; 20-94 yr) drawn at random from the Barwon Statistical Division, a population characteristic of Australia. Age- and weight- (and for three sites, height) matched reference ranges for BMD at the lumbar spine, proximal femur, forearm, and total body were developed using regression techniques. The cutoff BMD level for osteoporosis at the PA spine was 0.917 g/cm(2) and 0.713 g/cm(2) at the femoral neck according to the World Health Organization (WHO) guidelines. The upper cutoff level for osteopenia was 1.128 g/cm(2) at the PA spine and 0.913 g/cm(2) for the femoral neck. The proportion of Australian women categorized as having osteoporosis at the PA spine, femoral neck, or midforearm ranged from 0.9% among those aged 40-44 yr to 87.0% for those older than 79 yr. This study provides reference data representative of the Australian female population. A large proportion of elderly,Australian women has osteoporosis according to the WHO guidelines.
