◆アメリカの死亡率が中年層だけでなく高齢層でも増加しており、特に心血管疾患などの健康関連の要因が影響しています。高齢者への医療アクセスの不足も問題です。今後の研究と政策決定において、高齢者の死亡率の上昇とその原因に焦点を当てる必要があります。

Abstract
Since 2010, US life expectancy growth has stagnated. Much research on US mortality has focused on working-age adults given adverse trends in drug overdose deaths, other external causes of death, and cardiometabolic deaths in midlife. We show that the adverse mortality trend at retirement ages (65+ y) has in fact been more consequential to the US life expectancy stagnation since 2010, as well as excess deaths and years of life lost in 2019, than adverse mortality trends at working ages. These results reveal that the United States is experiencing a “double jeopardy” that is driven by both mid-life and older-age mortality trends, but more so by older-age mortality. Understanding and addressing the causes behind the worsening mortality trend in older ages will be essential to returning to the pace of life expectancy improvements that the United States had experienced for decades.
