目的：探讨日死亡人数与天气、环境空气污染的关系。我们收集了新西兰基督城（人口30万）从1988年6月到1993年12月的每日数据。我们使用泊松回归模型，控制季节使用的参数方法。结果：以上的第三个四分位数（20.5摄氏度）的最高温度，1摄氏度的增加与1%（95%CI：0.4至2.1%）的全因死亡率和3%（0.1至6.0%）的呼吸死亡率增加。PM10增加10 μ g/m3与全因死亡率增加1%（0.5 - 2.2%）和呼吸道死亡率增加4%（1.5 - 5.9%）相关（滞后一天后）。我们发现没有证据表明温度和颗粒空气pollutation.Conclusions的影响之间的相互作用：高温和颗粒空气污染是独立的与增加每日死亡率在基督城。事实上，这些结果是一致的，在其他国家的类似研究加强的论点，该协会很可能是causeal.Implications：这些研究结果有助于燃料燃烧的健康后果的证据，无论是在短期内（从当地的空气污染）和长期（从全球气候影响增加大气中的二氧化碳）。
Objective: To investigate the relationship between the daily number of deaths, weather and ambient air pollution.Method: An ecological study. We assembled daily data for the city of Christchurch, New Zealand (population 300,000) from June 1988 to December 1993. We used Poisson regression models, controlling for season using a parametric method.Results: Above the third quartile (20.5 degrees C) of maximum temperature, an increase of 1 degrees C was associated with a 1% (95% Cl: 0.4 to 2.1%) increase in all-cause mortality and a 3% (0.1 to 6.0%) increase in respiratory mortality. An increase in PM10 of 10 mu g/m(3) was associated (after a lag of one day) with a 1% (0.5 to 2.2%) increase in all-cause mortality and a 4% (1.5 to 5.9%) increase in respiratory mortality. We found no evidence of interaction between the effects of temperature and particulate air pollution.Conclusions: High temperatures and particulate air pollution are independently associated with increased daily mortality in Christchurch. The fact that these results are consistent with those of similar studies in other countries strengthens the argument that the associations are likely to be causal.Implications: These findings contribute to evidence of health consequences of fuel combustion, both in the short term (from local air pollution) and in the long term (from the global climatic effects of increased atmospheric CO2).
