已经提出了三个假设来预测低出生率和死亡率以及预期寿命增加的国家的人口健康变化。确定其中哪一种最能解释疾病和死亡模式的变化，是了解卫生干预措施对老龄化人口的公共卫生和经济影响的重要一步。这项研究的目的是使用西澳大利亚的数据链接系统来评估西澳大利亚州的压缩、扩张和动态平衡理论。研究人员利用预期寿命的变化、首次住院的平均年龄和处于慢性残疾或限制活动状态的时间来评估相互竞争的假设。在24年的研究期间，男性和女性的预期寿命分别增加了4.0岁和2.6岁。然而，男性和女性被诊断为慢性残疾的平均时间分别增加了9.2年和9.4年。这些结果表明，澳大利亚可能正在增加“更严重发病率的医学化”。
Three hypotheses have been advanced to predict changes in population health in countries experiencing low birth and death rates, and increasing expectation of life. Determining which of these best accounts for changing patterns of illness and death is an important step in understanding both the public health and economic impacts of health interventions in an ageing population. The aim of this study was to use the WA Data Linkage System to evaluate the compression, expansion and dynamic equilibrium theories in Western Australia. Changes in life expectancy, average age at first-time hospitalisation and time spent in chronic disabling or activity limiting states were used to evaluate the competing hypotheses.Life expectancy increased by 4.0 and 2.6 years over the 24-year study period in males and females, respectively. However, average time spent with a diagnosed chronic disabling condition increased by 9.2 and 9.4 years in males and females, respectively. These results suggest that an increase in the "medicalisation of more serious morbidity" may be in operation in Australia.
