To determine whether non-US citizens have a higher mortality risk of heat-related deaths than do US citizens.
We used place of residence reported in mortality data from the National Vital Statistics System from 2005 to 2014 as a proxy for citizenship to examine differences in heat-related deaths between non-US and US citizens. Estimates from the US Census Bureau American Community Survey of self-reported citizenship status and place of birth provided the numbers for the study population. We calculated the standardized mortality ratio and relative risk for heat-related deaths between non-US and US citizens nationally.
Heat-related deaths accounted for 2.23% (n = 999) of deaths among non-US citizens and 0.02% (n = 4196) of deaths among US citizens. The age-adjusted standardized mortality ratio for non-US citizens compared with US citizens was 3.4 (95% confidence ratio [CI] = 3.2, 3.6). This risk was higher for Hispanic non-US citizens (risk ratio [RR] = 3.6; 95% CI = 3.2, 3.9) and non-US citizens aged 18 to 24 years (RR = 20.6; 95% CI = 16.5, 25.7).
We found an increased mortality risk among non-US citizens compared with US citizens for heat-related deaths, especially those younger and of Hispanic ethnicity.
确定非美国公民因与热相关的死亡的死亡率是否高于美国公民。
我们使用国家生命统计系统 2005 年至 2014 年的死亡率数据中报告的居住地作为公民身份的代理，以检查非美国公民和美国公民之间与热相关的死亡差异。美国人口普查局美国社区调查的自我报告的公民身份和出生地的估计数为研究人群提供了数字。我们计算了全国非美国公民和美国公民与热相关的死亡的标准化死亡率比和相对风险。
与热相关的死亡占非美国公民死亡的 2.23%（n=999），占美国公民死亡的 0.02%（n=4196）。与美国公民相比，非美国公民的年龄调整标准化死亡率比为 3.4（95%置信区间[CI] = 3.2, 3.6）。西班牙裔非美国公民（风险比[RR] = 3.6；95% CI = 3.2, 3.9）和 18 至 24 岁的非美国公民的风险更高（RR = 20.6；95% CI = 16.5, 25.7）。
我们发现与热相关的死亡，非美国公民比美国公民的死亡率更高，尤其是年轻和西班牙裔的非美国公民。
