Women who had tough childhoods have immune cells that produce more reactive oxygen molecules, even though those molecules aren’t causing more DNA damage.
Scientific Claim
Childhood maltreatment is associated with increased mitochondrial reactive oxygen species (ROS) production in peripheral blood mononuclear cells of postpartum women, independent of direct DNA damage markers.
Original Statement
“In the same study cohort, we observed that telomeres... were significantly shorter... In study cohort I... CM was not only associated with alterations in mitochondrial activity, but also indicated an increase in cellular ROS production with increasing severity of CM experiences (34).”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim references a prior finding from the same cohort (34) and correctly frames it as an association, not a direct measurement in this paper. It avoids overstatement by acknowledging the source.

The Association of Childhood Maltreatment With Lipid Peroxidation and DNA Damage in Postpartum Women
The study looked at some signs of body stress from childhood trauma but didn’t measure the specific cellular energy factories (mitochondria) that produce harmful molecules called ROS, so it can’t say whether trauma increases those molecules as the claim suggests.
