孤独症与较差的健康结果有关，压力反应被认为是一种潜在的机制。本研究探讨了孤独感与心血管反应性（CVR）之间的关系是否在急性心理应激任务中存在差异。88名健康的年轻人完成了孤独的心理测量，并参加了标准化的心血管压力测试协议，包括公开演讲和心算任务。在急性应激暴露之前和期间评估心血管功能。较高水平的孤独显着预测较低的总外周阻力（TPR）反应的公开演讲任务，但不是算术的挑战。这表明，孤独对心血管反应性急性应激的影响可能因应激源类型而异。这些研究结果进行了讨论，在未来的研究。
Loneliness is connected to poorer health outcomes with stress reactivity proposed as an underlying mechanism. The present study explored whether the relationship between loneliness and cardiovascular reactivity (CVR) varies across acute psychological stress tasks. Eighty-eight healthy younger adults completed a psychometric measure of loneliness and participated in a standardised cardiovascular stress-testing protocol, with a public speaking and a mental arithmetic task. Cardiovascular functioning was assessed before and during the acute stress exposure. Higher levels of loneliness significantly predicted lower total peripheral resistance (TPR) reactivity to the public speaking task but not to the arithmetic challenge. This suggests that the effect of loneliness on cardiovascular reactivity to acute stress may vary by stressor type. These findings are discussed in relation to future research.
