Substantial epidemiologic literature has demonstrated the effects of air pollution and temperature on mortality. However, there is inconsistent evidence regarding the temperature modification effect on acute mortality due to air pollution. Herein, we investigated the effects of temperature on the relationship between air pollution and mortality due to non-accidental, cardiovascular, and respiratory death in seven cities in South Korea. We applied stratified time-series models to the data sets in order to examine whether the effects of particulate matter <10 μm (daily (pm10) 2000-2009. 828,787 a all and at between by cardiovascular daily data days deaths different each effect estimates extremely first from highest hot likelihood location maximum mean meta-analysis method. model, modified mortality non-accidental observed of on or overall pm10 pooled quantified random-effects ranges registered risk sets, temperature. temperature: temperatures the then through time-series using was were within>99th percentile) in individuals aged <65 ≥65 ( (daily 95-99th aged and between cardiovascular days effects extremely from harmful highest hot in mean mortality non-accidental not observed on or overall percentile). pm10 range risk strong temperature temperature: the there those very was were with years, years.>99th percentile) in men, with a very high temperature range (95-99th percentile) in women. Our findings showed that temperature can affect the relationship between the PM10 levels and cause-specific mortality. Moreover, the differences were apparent after considering the age and sex groups.
