Violence puts wear and tear on kids’ DNA
The health effects of trauma go deeper than one might expect.
DURHAM, N.C. — Children who have experienced violence might really be older than their years. The DNA of 10-year-olds who experienced violence in their young lives has been found to show wear and tear normally associated with aging, a Duke University study has found.
“This is the first time it has been shown that our telomeres can shorten at a faster rate even at a really young age, while kids are still experiencing stress,” said Idan Shalev, a post-doctoral researcher in psychology and neuroscience at the Duke Institute for Genome Sciences & Policy.
Telomeres are special DNA sequences found at the tips of chromosomes; much like the plastic tips of shoelaces, they prevent DNA from unraveling. Emerging evidence suggests that telomeres are “master integrators,” connecting stress to biological age and associated diseases….
