Body Mass Index and Mortality in Aboriginal Australians in Northern Territory: A Cohort Study

这项研究的最终目标是为土著人确定一个健康的体重范围。为了实现这一目标，我们将调查土著社区的体重和体重变化对健康的影响。我们将通过检查死亡率如何随体重变化来评估体重（以体重指数衡量）与死亡风险之间的关联。研究结果将对卫生专业人员向澳大利亚土著居民提供适当的建议以及土著居民采用与体重有关的健康生活方式产生重要影响。由于原住民与其他族群在体型、生理及环境因素上的差异，从其他族群获得的最适体重，可能并不适用于原住民族群。男性和女性的最佳体重不同吗？老年人和年轻人的最佳体重不同吗？这项研究将为回答诸如此类的各种问题提供证据。具有不同特征的个体可能具有不同的最佳体重值。这些信息有助于制定和修改澳大利亚土著居民的饮食指南。体重变化对健康影响的研究结果对于指导土著社区的体重控制方案具有重要意义。

The ultimate goal of this study is to define a healthy weight range for Aboriginal people. To fulfil this goal, we will investigate the health implications of body weight and weight change in Aboriginal communities. We will assess the association between body weight (as measured by body mass index) and the risk of death by examining how the death rate changes with body weight. The findings will have important implications for health professionals to provide adequate advice to Aboriginal Australians, and for Aboriginal people to adopt a healthy life style in relation to body weight. Due to the differences in body shape and physiological and environmental factors between Aborigines and other populations, the optimal body weight obtained from other populations may not be applicable to Aboriginal communities. Do males and females have different optimal body weights? Do old and young people have different optimal body weights? This study will provide evidence for answering various questions like these. Individuals with different characteristics may have different optimal body weight values. Such information is useful for the development and modification of dietary guidelines for Aboriginal Australians. The results on the health impact of weight change are important for guiding weight control programs in Aboriginal communities.
