Child abuse and physical health in adulthood.
Afifi, Tracie O, MacMillan, Harriet L, Boyle, Michael et al. · Health reports · 2016
Quick Summary
This study looked at whether experiencing abuse as a child is linked to physical health problems in adults. Researchers surveyed over 23,000 Canadian adults and found that people who experienced physical abuse, sexual abuse, or witnessed domestic violence as children were more likely to have various physical health conditions as adults, including chronic fatigue syndrome. These associations remained even after accounting for factors like smoking and obesity.
Why It Matters
This study provides population-level evidence that childhood trauma is associated with chronic fatigue syndrome in adulthood, suggesting that ME/CFS may be one of several chronic conditions with roots in early adversity. Understanding these associations helps ME/CFS researchers and clinicians recognize trauma as a potential contributing factor and may inform more compassionate, trauma-informed care approaches.
Observed Findings
- Childhood abuse (physical, sexual, or witnessing intimate partner violence) was associated with increased odds of having any physical condition (OR 1.4–2.0).
- Childhood abuse was specifically associated with chronic fatigue syndrome in adulthood, with stronger effects observed in women than men.
- The association between childhood abuse and back problems, migraine headaches, and bowel disease remained significant even after adjusting for mental health conditions and other physical conditions.
- Childhood abuse was associated with increased odds of obesity (OR 1.2–1.4) and reduced self-perceived general health.
Inferred Conclusions
- Childhood abuse is a risk factor for multiple chronic physical conditions in adulthood, including chronic fatigue syndrome.
- Sex differences exist in vulnerability to certain abuse-related physical health outcomes, with women showing stronger associations for several conditions.
- The relationship between childhood abuse and some physical conditions persists independently of mental health comorbidities, suggesting direct physiological pathways.
Remaining Questions
- What are the specific biological mechanisms linking childhood abuse exposure to chronic fatigue syndrome development?
- Do different types or intensities of childhood abuse produce differential effects on ME/CFS risk?
What This Study Does Not Prove
This study demonstrates association only, not causation—childhood abuse does not definitively cause chronic fatigue syndrome. The cross-sectional design cannot establish temporal relationships or rule out confounding factors. Additionally, self-reported physician diagnoses may not reflect clinically rigorous ME/CFS case definitions.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
