Black population in the United States experienced more than 1.63 million excess deaths and more than 80 million excess years of life lost, when compared with the White population over the last two decades, according to a new study published on Tuesday.

周二公布的一项新研究显示，在过去20年里，与白人相比，美国黑人的死亡人数增加了163万，寿命减少了8000多万年。

After a period of progress in reducing disparities, improvements stalled, and differences between the Black population and the White population worsened in 2020, according to the study published in the medical journal JAMA.

根据发表在医学杂志《美国医学会杂志》上的这项研究，在缩小差距方面取得了一段时间的进展后，改善停滞不前，黑人和白人之间的差异在2020年进一步恶化。

From 1999 to 2020, the disproportionately higher mortality rates in Black males and females resulted in 997,623 and 628,464 excess deaths, respectively, representing a loss of more than 80 million years of life, according to the study.

根据这项研究，从1999年到2020年，黑人男性和女性的死亡率过高，分别导致997623人和628464人死亡，这意味着损失了8000多万年的寿命。

Heart disease had the highest excess mortality rates, and the excess years of potential life lost rates were largest among infants and middle-aged adults, according to the study.

根据这项研究，心脏病的超额死亡率最高，婴儿和中年人的潜在寿命损失率最高。

Amid efforts in the United States to promote health equity, there is a need to assess recent progress in reducing excess deaths and years of potential life lost among the Black population compared with the White population, the study said.

该研究称，在美国促进健康公平的努力中，有必要评估最近在减少黑人与白人人口之间的超额死亡和潜在寿命损失方面取得的进展。
