Abstract：
Detrimental effects of early life stress on cardiovascular health are evident in adolescence. Cardiovascular reactivity and recovery in response to interpersonal stress may be a mechanism. This study aimed to evaluate if adolescent girls with higher early life stress demonstrated greater cardiovascular reactivity and slower recovery to peer rejection. A sample of 92 adolescent girls (age: M = 13.24) self-reported early life stressors. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were continuously measured before, during, and after a laboratory peer rejection paradigm. Counter to hypotheses, adolescent girls with higher early life stress had lower, not higher, HR during the recovery period. Early life stress was not associated with SBP or DBP recovery. Additionally, early life stress was not associated with SBP, DBP, or HR reactivity. Future research is needed to assess if blunted cardiovascular reactivity to interpersonal rejection during adolescence is a mechanism linking early life stress and later cardiovascular disease risk in women.
摘要：
早期生活压力对心血管健康的有害影响在青春期很明显。心血管反应性和对人际压力的恢复可能是一种机制。这项研究旨在评估早期生活压力较高的青春期女孩是否表现出更大的心血管反应性和对同伴排斥反应的恢复较慢。92名青春期女孩（年龄：M=13.24）自我报告的早期生活压力源的样本。收缩压（SBP），舒张压（DBP），和心率（HR）连续测量之前，during,在实验室同行拒绝范例之后。与假设相反，青春期女孩较高的早期生活压力较低，不是更高,恢复期间的HR。早期生活压力与SBP或DBP恢复无关。此外,早期生活压力与SBP无关，DBP,或HR反应性。需要进一步的研究来评估青春期对人际排斥反应的减弱的心血管反应是否是女性早期生活压力和后期心血管疾病风险的一种机制。
