目的：背景压力会增强还是减弱儿童对急性压力的心血管反应？方法：为了解决这个问题，根据 150 名儿童和青少年自我报告的背景压力水平，评估了他们对四种急性实验室压力源的心血管反应。背景压力是在标准化访谈中确定的，并根据其重要性、频率以及是否持续或已解决进行先验分类。结果：结果显示，报告重要压力源或持续且频繁的压力源的儿童和青少年在所有四种实验室压力源中表现出比低压力儿童和青少年更大的舒张压和总外周阻力升高。额外的分析表明，该结果不能用社会人口统计学变量或本研究中测量的人格特征来解释。结论：结果表明测量背景压力对于了解个人的急性压力反应非常重要。
Objective: Does background stress heighten or dampen children's cardiovascular responses to acute stress? Method: To address this question, the cardiovascular responses to four acute laboratory stressors of 150 children and adolescents were evaluated according to their self-reported background stress level. Background stress was determined during a standardized interview and was a priori classified according to its importance, frequency, and whether it was ongoing or resolved. Results: Results showed that children and adolescents who reported important stressors or stressors that were ongoing and frequent exhibited a larger increase in diastolic blood pressure and total peripheral resistance during all four laboratory stressors than their low stress counterparts. Additional analysis showed that the results could not be accounted for by sociodemographic variables or by the personality traits measured in this study. Conclusions: Results suggest the importance of measuring background stress in understanding an individual's acute stress response.
