童年逆境（CA）与青年精神病理学密切相关。确定减少CA后脆弱性的因素对于制定预防干预措施至关重要。迷走神经张力和迷走神经反应后，心理社会应激可能会影响心理病理学青少年暴露于CA。我们收集了157名13-17岁青少年在安静和特里尔社会应激试验（TSST）期间的心动周期和心阻抗图数据，以计算呼吸性窦性心律失常（RSA）和射血前期（PEP）。评估了CA的内化和外化症状以及多种形式。静息RSA和RSA反应性与CA在预测内化而非外化精神病理学方面相互作用; CA与高静息RSA和RSA反应性青少年的内化问题无关。未观察到与PEP的相互作用。高静息RSA预测TSST后更大的迷走神经反弹和加速的心率恢复，突出了一个潜在的机制，低内化症状后，CA的年轻人与高迷走神经张力。(C)2013 Wiley Periodicals，Inc.
Childhood adversity (CA) is strongly associated with youth psychopathology. Identifying factors that reduce vulnerability following CA is critical for developing preventive interventions. Vagal tone and vagal reactivity following psychosocial stressors might influence psychopathology among youths exposed to CA. We acquired heart period and impedance cardiography data to calculate respiratory sinus arrhythmia (RSA) and preejection period (PEP) from 157 adolescents aged 13-17 years at rest and during the Trier Social Stress Test (TSST). Internalizing and externalizing symptoms and multiple forms of CA were assessed. Resting RSA and RSA reactivity interacted with CA in predicting internalizing but not externalizing psychopathology; CA was unassociated with internalizing problems in adolescents with high resting RSA and RSA reactivity. No interactions were observed with PEP. High resting RSA predicted greater vagal rebound and accelerated heart rate recovery following the TSST, highlighting one potential mechanism underlying low internalizing symptoms following CA among youths with high vagal tone.
