慢性应激暴露可能导致心血管功能失调，增加非裔美国人心血管疾病的风险。本研究探讨了慢性应激暴露和应对方式对急性应激心血管反应性的直接和交互作用。非裔美国新兴成年人样本（n = 277）完成了一系列自我报告评估，并在两个时间点进行了特里尔社会压力测试（TSST）。在1个月的随访中，既往慢性应激暴露与女性心率（HR）反应性呈负相关。任务型应对方式与HR反应性呈正相关，回避型应对方式与HR反应性呈负相关。更高的使用情绪导向的应对缓和慢性应激暴露和HR反应之间的关系，导致更强大的反应。在女性中，但不是男性，较低的使用回避为导向的应对缓和之前的慢性压力暴露和HR反应之间的关系，也导致更强大的反应。先前的慢性应激暴露和使用适应不良的应对策略可能会对心血管反应产生负面影响，特别是在非洲裔美国女性中。使用适应性应对方式可以减轻这些影响，改善心血管反应性。这些研究结果提供了初步的支持，心理健康的决定因素在一个控制的实验室实验，并强调重要的性别差异，考虑在预防工作中的非洲裔美国人心血管健康的差距。
Chronic stress exposure may contribute to dysregulation of cardiovascular functions and increase CVD risk among African Americans. This study investigated the direct and interactive effects of chronic stress exposure and coping styles on cardiovascular reactivity to acute stress. A sample of African American emerging adults (n = 277) completed a battery of self-report assessments and underwent the Trier Social Stress Test (TSST) across two time points. Prior chronic stress exposure was negatively associated with heart rate (HR) reactivity among females at 1-month follow-up. Task-oriented coping was positively associated with HR reactivity, while avoidance-oriented coping showed a negative association. Higher use of emotion-oriented coping moderated the relationship between chronic stress exposure and HR reactivity, resulting in more robust reactivity. Among females, but not males, lower use of avoidance-oriented coping moderated the relationship between prior chronic stress exposure and HR reactivity, also resulting in more robust reactivity. Prior chronic stress exposure and the use of maladaptive coping strategies may confer negative impacts on cardiovascular reactivity, particularly among African American females. Using adaptive coping styles may mitigate these effects and improve cardiovascular reactivity. These findings provide preliminary support for psychosocial determinants of health within a controlled laboratory experiment and highlight important gender differences to consider in prevention efforts for African American cardiovascular health disparities.
