Effect modification in the temperature extremes by mortality subgroups among the tropical cities of the Philippines

摘要

BackgroundTemperature–mortality relationships have been extensively probed with varying temperature range but with relatively similar patterns and in some instances are being modified by specific mortality groups such as causes of mortality, sex, and age.ObjectiveThis study aimed to determine the risk attributions in the extreme temperatures and also identified the risks associated with the various mortality subgroups.DesignWe used the 2006–2010 daily average meteorological and daily mortality variables from the Philippine Atmospheric Geophysical and Astronomical Services Administration and Philippine Statistics Authority–National Statistics Office, respectively. Mortality data were divided according to cause (cardiovascular and respiratory), sex, and age (0–14 years, 15–64 years, and 64 years). We performed a two-stage analysis to estimate the extreme temperature effects stratified by the different mortality subgroups to observe the effect modification.ResultsIn the pooled analysis, greater risks were o...
