What did studies of Childhood social class find?
1Studies of Childhood social class measured 1 outcome; the most studied are rate of cognitive change (1 study).
Rate of cognitive change
no changein humans1
1 study
Rate of cognitive change
no changein humans1
Childhood social class was not clearly linked with rate of cognitive change in humans.
“Childhood social class was significantly associated with mean-level cognitive performance at age 65 y, but not with rate of cognitive change.”

What is Childhood social class linked with?
3Studies link Childhood social class with 3 measures, most often PhenoAge age acceleration (1 study), Hannum DNA methylation age (1) and cognitive function (1).

PhenoAge age acceleration

Childhood social class is associated with PhenoAge age acceleration in humans (3.6 years greater (95% CI 1.8 to 5.4)).

Childhood social class is associated with cognitive function in humans.
