Key result
Higher levels of childhood maltreatment were associated with higher levels of depressive symptoms, but only among young adults who exhibited lower tonic respiratory sinus arrhythmia.
Why the study?
The goal was to investigate the moderating effect of tonic respiratory sinus arrhythmia in the relation between childhood maltreatment and depression symptoms among young adults.

Tonic RSA may moderate maltreatment-depression links in young adults; hypothesis-generating, needs prospective validation before clinical use.
The goal of the current study was to investigate the moderating effect of tonic respiratory sinus arrhythmia (RSA) in the relation between childhood maltreatment and depression symptoms among young adults. A total of 98 participants (70 women) aged 17-22 years completed questionnaires on childhood maltreatment and depressive symptoms. RSA data were obtained during a resting condition in the laboratory. Results indicated that childhood maltreatment interacted with tonic RSA to predict depressive symptoms, even after controlling for age and body mass index (BMI) of each participant. Specifically, higher levels of childhood maltreatment were associated with higher levels of depressive symptoms, but only among young adults who exhibited lower tonic RSA. The results indicated that the association between childhood maltreatment and depressive symptoms depends on young adults' physiological functioning/flexibility. Findings suggest that consideration of external environmental factors in combination with internal physiological factors is critical to understand young adults' mental health.

Zhang et al. (2021) conducted a cross-sectional in Depressive symptoms (n=98). Childhood maltreatment and tonic respiratory sinus arrhythmia was evaluated on Depressive symptoms. Higher levels of childhood maltreatment were associated with higher levels of depressive symptoms, but only among young adults who exhibited lower tonic respiratory sinus arrhythmia.
