先前的实验室研究表明，与非孤独的年轻人相比，孤独的年轻人有更高的基础总外周阻力（TPR）和更低的心输出量（CO）。本研究采用经验采样的方式获取动态血压；阻抗心动图；以及活动、评估、互动和健康行为的报告。结果证实，在正常的一天中，孤独会导致较高的 TPR 和较低的 CO。孤独并不能预测独处时间、日常活动或健康行为的差异，但确实可以预测更高的压力评估和更差的社交互动。与孤独无关，互动质量有助于 TPR。孤独差异不是由抑郁情绪或神经质介导的。社会支持调节压力和威胁中的孤独差异。男性和女性的孤独感是相似的。
Prior lab research revealed higher basal total peripheral resistance (TPR), and lower cardiac output (CO) in lonely than in nonlonely young adults. In this study, experience sampling was used to obtain ambulatory blood pressure; impedance cardiography; and reports of activities, appraisals, interactions, and health behaviors. Results confirmed that loneliness predicted higher TPR and lower CO during a normal day. Loneliness did not predict differences in time spent alone, daily activities, or health behaviors but did predict higher stress appraisals and poorer social interactions. Independent of loneliness, interaction quality contributed to TPR. Loneliness differences were not mediated by depressed affect or neuroticism. Social support mediated loneliness differences in stress and threat. Concomitants of loneliness were comparable for men and women.
