Abstract
A substantial number of epidemiological studies have demonstrated an association between atmospheric conditions and human allcause as well as causespecific mortality However most research has been performed in industrialised countries whereas little is known about the atmosphere–mortality relationship in developing countries Especially with regard to modifications from nonatmospheric conditions and intrapopulation differences there is a substantial research deficit Within the scope of this study we aimed to investigate the effects of heat in a multistratified manner distinguishing by the cause of death age gender location and socioeconomic status We examined 22840 death counts using semiparametric Poisson regression models adjusting for a multitude of potential confounders Although Bangladesh is dominated by an increase of mortality with decreasing equivalent temperatures over a wide range of values the findings demonstrated the existence of partly strong heat effects at the upper end of the temperature distribution Moreover the study demonstrated that the strength of these heat effects varied considerably over the investigated subgroups The adverse effects of heat were particularly pronounced for males and the elderly above 65 years Moreover we found increased adverse effects of heat for urban areas and for areas with a high socioeconomic status The increase in and acceleration of urbanisation in Bangladesh as well as the rapid aging of the population and the increase in noncommunicable diseases suggest that the relevance of heatrelated mortality might increase further Considering rising global temperatures the adverse effects of heat might be further aggravated
