childhood adversity increases lifelong inflammation
In plain terms: Does early-life trauma permanently raise adult inflammation?
Yes — childhood trauma is associated with elevated adult inflammatory markers decades later (meta-analysis + birth-cohort data), though the effect is modest and not found in every cohort.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
