As someone who's spent 26 years in GA and met many folks also in AA and NA, I estimate that at least 80% have had childhood trauma. True for me, true for my eldest child.

It really is a silent crisis and difficult to get a hold on the scale of it. To the point where it feels like everyone has some kind of trauma, but that might just be the circles I'm in.

A friend who is counselor and head priest at a girls’ Catholic school thinks it’s a large factor behind the childhood obesity epidemic too. Not just sexual abuse but childhood trauma in general leading to food as a coping mechanism.

His offhand theory is that the increase in the prevalence of restaurants and hyperpalatable foods gave people an outlet to feel safe (a third place in public where the whole family goes and acts their best) and the hyperpalatable food gave an easy and cheap dopamine boost during hard times leading to a spiral.

True in prison as well. The setting doesn't encouraging grappling with it in those terms like rehab does. But it's easy to see anyway.
