Background
A number of studies have examined the relationship between high ambient temperature and mortality. Recently, concern has arisen about whether this relationship is modified by socio-demographic factors. However, data for this type of study is relatively scarce in subtropical/tropical regions where people are well accustomed to warm temperatures.Objective
To investigate whether the relationship between daily mean temperature and daily all-cause mortality is modified by age, gender and socio-economic status (SES) in Brisbane, Australia.Methods
We obtained daily mean temperature and all-cause mortality data for Brisbane, Australia during 1996-2004. A generalised additive model was fitted to assess the percentage increase in all deaths with every one degree increment above the threshold temperature. Different age, gender and SES groups were included in the model as categorical variables and their modification effects were estimated separately.Results
A total of 53,316 non-external deaths were included during the study period. There was a clear increasing trend in the harmful effect of high temperature on mortality with age. The effect estimate among women was more than 20 times that among men. We did not find an SES effect on the percent increase associated with temperature.Conclusions
The effects of high temperature on all deaths were modified by age and gender but not by SES in Brisbane, Australia. 相似文献2.

As a prolonged period of Australian prosperity ends, attention has now begun to turn to the likely impacts of a severe economic downturn. The pain of recession is unlikely to be evenly distributed across the population or across space. Not that the previous economic good fortune was evenly spread across society. It is, therefore, expected that a new layer of socio-economic stress will be laid over existing patterns of social and spatial disparity. In this context, questions of deprivation and social exclusion are an important ongoing concern. Deprivation and social exclusion are operative at a number of levels of society. Neo-liberal thought and policy has been directed at the level of the individual. However, space and place are also important, as spatially concentrated disadvantage has structural consequences for both individual fortunes and the broader social fabric. This article considers the spatial distribution of disadvantage across our major metropolitan regions and considers potential approaches to address social exclusion in our suburban heartlands. 相似文献
