大量流行病学文献已经证明了空气污染和温度对死亡率的影响。然而，关于温度变化对空气污染引起的急性死亡率的影响，证据并不一致。在此，我们调查了温度对韩国七个城市空气污染与非意外死亡、心血管死亡和呼吸系统死亡之间关系的影响。我们对数据集应用分层时间序列模型，以检验65岁人群中颗粒物（99百分位数）的影响，PM10与非意外或心血管死亡之间的最高总体风险是否出现在非常炎热的天气，而不是在极端炎热的天气（日平均温度：95-99百分位数）。PM10对非意外死亡率有强烈的有害影响，男性的温度范围最高（99 -99百分位数），女性的温度范围非常高（95-99百分位数）。我们的研究结果表明，温度可以影响PM10水平与病因特异性死亡率之间的关系。此外，考虑到年龄和性别群体，差异也很明显。(C) 2015 Elsevier B.V.版权所有
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 99th percentile) in individuals aged = 65 years, the highest overall risk between PM10 and non-accidental or cardiovascular mortality was observed on very hot days and not on extremely hot days (daily mean temperature: 95-99th percentile). There were strong harmful effects from PM10 on non-accidental mortality with the highest temperature range (>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. (C) 2015 Elsevier B.V. All rights reserved.
