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.
🧭 Read this score with how it was built in mindStudies we had treated as independent turned out to share a research group
No new research arrived, and nothing about the studies changed. Three of the papers supporting this claim are three reports from ONE study — the Dunedin Multidisciplinary Health and Development Study, which has followed the same 1,037 people born in Otago, New Zealand in 1972-73 for their whole lives. Our database had them recorded as three separate research groups, so one cohort was casting three independent-looking votes. They now count as one. The finding itself is unchanged and still points the same way; we are simply no longer counting a single long-running study three times.

What the evidence shows
Childhood adversity is associated with higher adult inflammatory markers decades later, in cohorts of 138,000 and 153,000 adults where each additional adversity domain predicted more inflammation. It is observational and a 25-study review found inconsistent evidence for sensitive periods, so the association is robust while the timing and mechanism are not.

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).
