The study looked at 237 rhesus macaques. I can only read the abstract, which doesn't clarify how they determined their early life adversity.

The abstract doesn't make very strong claims about how much an impact they saw, only that they started to see some patterns emerge.

The patterns were also not even consistent in the same direction, with some of their measurements correlating adversity with changes that "looked like" the opposite of accelerated aging.

> "In some cases, adversity-related changes looked like accelerated aging. In others, they went in the opposite direction," explained co-lead author Rachel Petersen

I would like to read the full paper, but this feels like there are several layers of PR speak on top of what they were studying.

Many factors can impact the markers they're measuring, including body size, so this paper shouldn't be used as evidence that we can measure trauma directly or anything like that. They were searching for patterns and differences, but there isn't a clear or even uni-directional link with adversity.
