在文献中，敌意和不良健康结果的相关性并不一致。自我调节和皮质醇分泌可能在区分那些有更大风险的负面健康结果的敌对个体方面发挥重要作用。在本研究中，我们试图检查是否具有高自我调节强度，高应激诱导的高频心率变异性（HF-HRV），缓冲敌意对皮质醇分泌的影响。参与者（N = 213）完成了自我报告的敌意和测量HF-HRV在休息和社会压力任务。唾液样本收集之前立即（一个样本），并超过50分钟后（六个样本），压力任务，以评估皮质醇分泌随时间的推移。敌对的个体不太可能表现出皮质醇敏感性（即，皮质醇随时间的高变化）。鉴于皮质醇敏感性通过糖皮质激素抵抗和炎症增加代谢和炎症性疾病的风险，这些发现很重要。因此，增加应激诱导的HF-HRV的干预措施可能会减少敌意对健康结果的影响。
Hostility and adverse health outcomes are inconsistently associated in the literature. Self-regulation and cortisol secretion may play important roles in differentiating those hostile individuals who are at greater risk of negative health outcomes from those who are not. In the present study, we sought to examine if having high self-regulatory strength, as indexed by high stress-induced high-frequency heart rate variability (HF-HRV), buffered the effects of hostility on cortisol secretion. Participants (N = 213) completed a self-report measure of hostility and measurement of HF-HRV at rest and during a social stress task. Saliva samples were collected immediately before (one sample), and over a 50 minute period after (six samples), the stress task to evaluate cortisol secretion over time. Hostile individuals were less likely to demonstrate cortisol sensitivity (i.e., high change in cortisol over time) when they had high stress-induced HF-HRV. Such findings are important given that cortisol sensitivity increases risk of metabolic and inflammatory disorders via glucocorticoid resistance and inflammation. Therefore, interventions that increase stress-induced HF-HRV may reduce the impact of hostility on health outcomes.
