UNLABELLED
There is a well-established relationship between high ambient temperature and risk of death. However, the number of deaths attributable to heat each year in the United States remains incompletely quantified.
METHODS
We replicated the approach from a large, international study to estimate temperature-mortality associations in 297 United States counties and additionally calculated the number of deaths attributable to heat, a quantity of likely interest to policymakers and the public.
RESULTS
Across 297 counties representing 61.9% of the United States population in 2000, we estimate that an average of 5,608 (95% empirical confidence interval = 4,748, 6,291) deaths were attributable to heat annually, 1997-2006.
CONCLUSIONS
Our results suggest that the number of deaths related to heat in the United States is substantially larger than previously reported.
未标注
环境高温与死亡风险之间存在既定的关系。然而，美国每年因高温导致的死亡人数仍未得到完全量化。
方法
我们采用了一项大型国际研究的方法，来估计美国297个县的温度与死亡率之间的关联，并额外计算了因高温导致的死亡人数，这一数量可能是政策制定者和公众感兴趣的。
结果
在代表2000年美国61.9%人口的297个县中，我们估计在1997 - 2006年期间，每年平均有5608例（95%经验置信区间 = 4748, 6291）死亡可归因于高温。
结论
我们的结果表明，美国与高温相关的死亡人数比之前报道的要多得多。
