Social subordination
Social subordination has been studied in 3 papers since 2019: none in people yet, 3 in animals. The research so far is in animals. The newest paper, Jan 26, 2022: “Early-life experience shapes patterns of senescence in a food-caching passerine”.

What did studies of Social subordination find?
4Studies of Social subordination measured 4 outcomes; the most studied are reproductive senescence (1 study), blood glucose (1) and IL-1β and IL-6 (1).

Reproductive senescence
upin P. canadensis1
Social subordination increases reproductive senescence in P. canadensis (until 6 years of age before declining).
“using 39 years of breeding data, we demonstrate that Ejectee males advanced laying dates and increased the annual number of nestlings until 6 years of age before declining”

What is Social subordination linked with?
1Studies link Social subordination with 1 measure, most often inflammation (1 study).
