PMID 39616435WHAT IT FOUND
Women with intimate partner violence who had a childhood brain injury were significantly more likely to have sustained a brain injury from a partner in adulthood.
This association held even after accounting for childhood trauma, age, and education. The study cannot prove causation due to its cross-sectional design.
Key findings
01Participants who sustained at least 1 childhood brain injury from any mechanism were statistically significantly more likely to sustain an IPV-related brain injury in adulthood.
02The association between childhood brain injury and adult IPV-related brain injury remained significant after adjusting for age, education, and childhood trauma.
03An exploratory analysis found that non-abuse-related childhood brain injuries were significantly associated with adult IPV-related brain injuries, but abuse-related childhood injuries were not.

What it does not show
The cross-sectional design prevents causal inference or risk estimation. Brain injury history was self-reported retrospectively, introducing potential recall bias. The sample was predominantly White and highly educated, limiting generalizability. The exploratory analysis separating abuse-related from non-abuse-related childhood injuries had low statistical power.
Declared interests
The study was supported by the National Institutes of Health. No specific commercial conflicts of interest were declared in the provided text.
The easy way to misread this
Do not interpret the lack of statistical significance for abuse-related childhood brain injuries as evidence that they are not a risk factor. This result came from a small, underpowered exploratory analysis, and the overall association between any childhood brain injury and adult IPV-related injury remains strong.
