 This study found that maternal parenting stress is linked to changes in DNA methylation in both mothers and their children. Specifically, it was found that mothers who experienced more stress had lower levels of methylation on a gene called PRP1, which is involved in stress signaling. This gene was also found to be less methylated in the children of these mothers. These findings suggest that maternal stress can have long-term effects on the health of both parents and their offspring.
