关于澳大利亚骨折率的人口数据很少。我们确定了居住在一个特定地区（人口218000）的35岁及以上成年人在2年内发生的所有骨折，代表了澳大利亚人口。本研究的主要优势在于骨折的全面确定，这是通过定期搜索基隆骨质疏松研究地区仅有的两家放射学提供者来确保的。然而，由于我们的确定依赖于医学影像学检查的临床指征，椎骨骨折可能被低估。在35 - 55岁的人群中，男性的骨折率（每10 000人/年）约为女性的两倍（65人对35人）。60岁以上女性的骨折率几乎是55岁以下女性的7倍。相比之下，60岁以上男性的骨折率仅比55岁以下男性高50%（72 vs 104）。女性和男性的骨折发生率最高的部位是髋部（分别为28和10）、脊柱（21和7）、前臂远端（Colles '）（18和4）和肱骨（11和3），女性比男性高3-4倍。这些骨折占女性所有骨折的63%，男性占32%。相比之下，女性和男性的小腿和踝关节骨折发生率均低于10/10000，并且随着年龄的增长而增加。与其他人群的回顾性调查相比，髋部骨折发生率似乎很高，特别是在老年人群中。与许多其他国家一样，澳大利亚人口的寿命越来越长。在1991年至1996年澳大利亚全国人口普查的五年中，90岁及以上的妇女人数增加了32%，这一年龄段的男子人数增加了48%。鉴于骨折率稳定，与年龄有关的骨折，特别是髋部骨折，对妇女和男子造成的重大健康负担将继续增加。
There is little population-based data concerning fracture rates in Australia. We ascertained all fractures occurring during 2 years in adults aged 35 years and over residing within a defined region (population 218 000), representative of the Australian population. The major strength of this study is the comprehensive ascertainment of fractures, which was ensured by regular searches of the only two radiologic providers in the Geelong Osteoporosis Study region. Nevertheless, vertebral fractures are likely to be underestimated since our ascertainment relied on a clinical indication for a medical imaging procedure. Among those aged 35 - 55 years, the fracture rate (persons per 10 000/year) in men was about double the rate in women (65 vs 35. The fracture rate was almost 7 times higher in women over 60 years versus women less than 55 years of age. In contrast, the fracture rate in men over 60 years was only 50% higher than in men less than 55 years of age (72 vs 104). Fracture rates in women and men were highest at the hip (28 and 10 respectively), spine (21 and 7), distal forearm (Colles') (18 and 4) and humerus (11 and 3), and were 3-4 times higher in women than men. These fractures accounted for 63% of all fractures in women and 32% in men. By contrast, the rate of lower leg and ankle fractures was less than 10 per 10 000 in both women and men and did not increase to the same extent with age. Hip fracture rates appear high, particularly among the older age strata, compared with retrospective ascertainment in other populations. In Australia, as in many other countries, there is an increasing longevity of the population. The number of women aged 90 years and over increased by 32% and the number of men of this age increased by 48% in the 5 years between the Australian national census of 1991 and 1996. Given stable fracture rates, the substantial health burden imposed by age-related fractures, particularly hip fractures, will continue to escalate in both women and men.
