Even if someone had a rough childhood, their blood doesn't show more signs of DNA damage from oxidative stress after having a baby, based on multiple tests.
Scientific Claim
Childhood maltreatment load shows no significant association with oxidative DNA damage in postpartum women, as measured by comet assay, γH2AX staining, and serum 8-OH(d)G levels across two independent cohorts totaling 147 participants.
Original Statement
“In study cohort I, the analyses revealed no significant main effects of maltreatment load on tail intensity (b = −0.0011, p = 0.95) and tail moment (b = −0.0035, p = 0.83). These results were confirmed by γH2AX fluorescence staining... In study cohort II... no significant association between maltreatment load and the serum levels of 8-OH(d)G.”

Assessment Explanation
The study design is observational and reports non-significant associations with precise p-values. The claim correctly uses 'no significant association' and avoids causal language.

The Association of Childhood Maltreatment With Lipid Peroxidation and DNA Damage in Postpartum Women
The researchers checked if growing up with trauma leads to more DNA damage in new moms, using three different tests—and found no link. So, trauma didn’t seem to cause more DNA damage in these women.
