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
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
