It’s interesting how long it takes for solid research to be integrated into daily life, especially research that produces results that shock us, but that we have somehow understood at some deep level all along. The CDC’s ACE Study — which linked childhood trauma with the adult onset of chronic disease, including mental illness, and violence or being a victim of violence — is one of those research studies.
Tuesday’s roundup featured a story about how exposure to child abuse and bullying affected our DNA, showing that stress leads to accelerated biological aging. Stephanie Pappas did a good story about the research in LiveScience, in which she quoted Dr. Elissa Epel, a University of California, San Francisco, health psychologist who studies stress and cell aging.
“Now we have some evidence that indeed children’s immune-system aging can be adversely affected by severe stress early in childhood, a scar that could last possibly decades later,” Epel told LiveScience. “This study underscores the vital importance of reducing violent exposures for children — both serious bullying and abuse in the family.”
The researchers pointed out that the violence doesn’t have to affect the child physically — it’s the cumulative stress that’s affecting the DNA.
