Sol,
I am interested in the source for those statistics too. I tried googling keywords to try to find it, but the best I could find was “DNA methylation signatures of childhood trauma predict psychiatric disorders and other adverse outcomes 17 years after exposure.” (Mol Psychiatry. .)
https://pubmed.ncbi.nlm.nih.gov/35546634/
Only the abstract is free to view, the full article is pay-per-view, so I’ve only read the abstract.
There is an article (not a research paper) that touches on epigenetics (DNA methylation is one of several epigenetic mechanisms that cells use to control gene expression) and a therapist that works with prison inmates. “Unlocking Violent Crime Through Epigenetics” (Deutsche Welle) https://amp.dw.com/en/unlockin...igenetics/a-45964140
