Abstract：
UNASSIGNED: Pneumonia is one of the most common causes of hospital admissions in the United States and remains a major cause of death. However, less is known regarding the mortality burden from pneumonia in the United States and how this burden has changed over time.
UNASSIGNED: Death rates from causes related to pneumonia were determined using the CDC Wide-ranging Online Data for Epidemiologic Research (WONDER) data from 1999-2019. Pneumonia deaths were calculated for the overall population as well as for sociodemographic subgroups. We also analysed changes in death rates over time.
UNASSIGNED: Overall, 2.1% of total US deaths during the period between 1999 and 2019 were due to pneumonia (2.6% in 1999 and 1.5% in 2019). Mortality declined over time for both men and women, and across most age cohorts, as well as all racial, urbanisation, and regional categories. Rates of pneumonia deaths were higher among males as compared to females (age-adjusted mortality rate ratio (AAMRR) = 1.35; 95% CI: 1.34-1.35). Compared to White Americans, Black Americans had the highest pneumonia-related mortality rates of any racial group (AAMRR = 1.11; 95% CI: 1.10-1.11).
UNASSIGNED: Rates of pneumonia-related death have decreased in the United States in recent decades. However, significant racial and gender disparities remain, indicating the need for more equitable care.

摘要：
■肺炎是美国住院的最常见原因之一，仍然是死亡的主要原因。然而,在美国，人们对肺炎的死亡负担以及这种负担随时间的变化知之甚少。
■使用1999-2019年CDC广泛的流行病学研究在线数据（WONDER）数据确定与肺炎相关的原因死亡率。计算了总人口以及社会人口统计学亚组的肺炎死亡人数。我们还分析了死亡率随时间的变化。
■总的来说，1999年至2019年期间，美国总死亡人数的2.1％是由于肺炎（1999年为2.6％，2019年为1.5％）。随着时间的推移，男性和女性的死亡率都在下降，在大多数年龄组中，以及所有种族，城市化,和区域类别。与女性相比，男性的肺炎死亡率更高（年龄调整后的死亡率（AAMRR）=1.35；95％CI：1.34-1.35）。与美国白人相比，在所有种族中，黑人美国人的肺炎相关死亡率最高（AAMRR=1.11；95％CI：1.10-1.11）。
■近几十年来，美国肺炎相关死亡率有所下降。然而,显著的种族和性别差异仍然存在，这表明需要更公平的照顾。
