Key result
Lower high-frequency heart rate variability significantly increased the risk of developing PTSD in physically injured patients with a history of childhood abuse (OR 1.62), but not in those without.
Why the study?
This study examined the moderating effects of childhood abuse histories on the associations between heart rate variability components and the development of post-traumatic stress disorder.
Do lower LF and HF components of heart rate variability predict the development of PTSD in physically injured adults, and is this moderated by childhood abuse history?

Childhood abuse history significantly amplifies the risk of developing PTSD associated with lower heart rate variability following physical injury, highlighting the need for integrated physiological and psychological screening.
Childhood abuse may moderate post-injury HRV-PTSD links; leaves open targeted screening or monitoring before clinical adoption.
Introduction: This study examined the moderating effects of childhood abuse histories on the associations between low frequency (LF) and high frequency (HF) components of heart rate variability (HRV) and the development of post-traumatic stress disorder (PTSD). Methods: Participants with physical injuries were recruited from a trauma center and followed for two years. Baseline assessments included LF, HF, and childhood abuse histories, assessed using the Nemesis Childhood Trauma Interview. Socio-demographic and clinical covariates were obtained. PTSD diagnoses were made at 3, 6, 12, and 24 months post-injury using the Clinician-Administered PTSD Scale for DSM-5. Logistic regression analyses assessed the associations. Results: Among 538 participants, 58 (10.8%) developed PTSD during the study period. A significant interaction was found: lower LF/HF were significantly associated with PTSD in patients with childhood abuse histories, but not in those without. Conclusion: Childhood abuse history significantly moderates the relationship between LF-HF HRV components and PTSD development, suggesting that childhood adversities amplify the risk. These findings support the importance of screening for childhood abuse histories and monitoring HRV in physically injured patients as part of the assessment process.

Jeon et al. (2024) conducted a cohort in Physical injuries and post-traumatic stress disorder (n=538). Lower heart rate variability (LF and HF components) with childhood abuse history vs. Higher heart rate variability or absence of childhood abuse history was evaluated on Development of PTSD over 2 years (OR 1.62, 95% CI 1.32-2.07, p=<0.01). Lower high-frequency heart rate variability significantly increased the risk of developing PTSD in physically injured patients with a history of childhood abuse (OR 1.62), but not in those without.
