近期一项研究发现,衰老过程是不可阻挡的

Aging process is unstoppable, finds unprecedented study

这项由14个国家的科学家以及牛津大学的专家组成的国际合作研究旨在测试“不变的衰老速率”假说,该假说认为,一个物种从成年开始衰老的速率是相对固定的。

The study, by an international collaboration of scientists from 14 countries and including experts from the University of Oxford, set out to test the “invariant rate of ageing” hypothesis, which says that a species has a relatively fixed rate of ageing from adulthood.

牛津大学Leverhulme人口科学中心的José Manuel Aburto分析了跨越几个世纪和各大洲的年龄特定出生和死亡数据,他说:“我们的发现支持了这样一种理论,即由于年轻时死亡率的降低,更多的人活得更长,而不是延缓了死亡。”

“Our findings support the theory that, rather than slowing down death, more people are living much longer due to a reduction in mortality at younger ages,” said José Manuel Aburto from Oxford’s Leverhulme Centre for Demographic Science, who analysed age-specific birth and death data spanning centuries and continents.

Aburto说:“我们比较了人类和非人类灵长类动物的出生和死亡数据,发现所有灵长类动物的死亡模式都是相同的。”“这表明,最终控制寿命的是生物因素,而不是环境因素。”

“We compared birth and death data from humans and non-human primates and found this general pattern of mortality was the same in all of them,” said Aburto. “This suggests that biological, rather than environmental factors, ultimately control longevity.”

“统计数据证实,随着健康和生活条件的改善,个人寿命延长,这导致整个人口的寿命增加。然而,随着年龄的增长,死亡率会急剧上升,这在所有物种中都很明显。”

“The statistics confirmed, individuals live longer as health and living conditions improve which leads to increasing longevity across an entire population. Nevertheless, a steep rise in death rates, as years advance into old age, is clear to see in all species.”
