Abstract

While the mental health challenges posed by quarantine are well-documented, its physiological effects remain less understood. We examined cardiovascular trajectories over a 6-day quarantine following common cold infection, utilizing data from the Pittsburgh Cold Study 3 (n = 213, 2007–2011). Specifically, we explored the relationship between depressive mood and heart rate (HR) patterns, hypothesizing that individuals prone to depressive mood might experience altered arousal during quarantine. We conducted similar analyses for blood pressure (BP) as well. Our findings revealed that, on average, HR increased during quarantine. Notably, individuals reporting higher depressive mood levels exhibited lower initial HR but experienced a sharper increase throughout the quarantine period. In contrast, no significant linear or quadratic changes were observed in systolic blood pressure (SBP). However, initial analyses did identify significant linear changes in diastolic blood pressure (DBP) and mean arterial pressure (MAP). These changes in DBP and MAP were not influenced by depressive mood and lost significance in sensitivity analyses that accounted for infection-related factors, health behaviors, and socio-demographic variables. Interestingly, HR trajectories remained significant in sensitivity analyses but lost significance when self-reported symptoms were included. Self-reported symptoms partially mediated the relationship between depressive mood and HR increases, suggesting that individuals with higher depressive tendencies also reported more infection-related symptoms, contributing to increased HR. These findings highlight how midterm social isolation can elevate HR, particularly in individuals prone to depressive mood. However, the absence of a control group limits broader interpretations, emphasizing the need for further research.
社会隔离期间心率增加:抑郁情绪和自述感染症状的关系
虽然隔离带来的心理健康挑战有据可查,但其生理影响仍鲜为人知。我们利用匹兹堡感冒研究3 (n = 213,2007-2011)的数据,检查了普通感冒感染后6天隔离期间的心血管轨迹。具体来说,我们探讨了抑郁情绪与心率(HR)模式之间的关系,假设容易抑郁情绪的个体在隔离期间可能会经历觉醒改变。我们也对血压(BP)进行了类似的分析。我们的研究结果显示,平均而言,在隔离期间,HR增加了。值得注意的是,报告抑郁情绪水平较高的个体表现出较低的初始HR,但在整个隔离期间经历了更急剧的增长。相比之下,收缩压(SBP)没有明显的线性或二次变化。然而,最初的分析确实确定了舒张压(DBP)和平均动脉压(MAP)的显著线性变化。DBP和MAP的这些变化不受抑郁情绪的影响,在考虑感染相关因素、健康行为和社会人口变量的敏感性分析中失去了意义。有趣的是,HR轨迹在敏感性分析中仍然显着,但在包括自我报告的症状时失去了意义。自我报告的症状部分介导了抑郁情绪与HR增加之间的关系,这表明抑郁倾向较高的个体也报告了更多的感染相关症状,从而导致HR增加。这些发现强调了中期社会孤立是如何提高人力资源的,特别是对那些容易抑郁的人来说。然而,缺乏对照组限制了更广泛的解释,强调了进一步研究的必要性。

期刊介绍: Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane. The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
