To examine heart rate (HR) responses to and coping with stress in children with recurrent abdominal pain (RAP), anxiety, and healthy controls.
A clinical sample (children with RAP and children with anxiety) was compared to control children on self-reported and HR responses to stress and a laboratory test of pain tolerance and intensity (cold pressor).
Children in the clinical sample had elevated HRs compared to healthy controls before, during, and after laboratory tasks. Self-reported stress reactivity to social stress was positively correlated with HR at all study time intervals. Secondary control coping with social stress was negatively correlated with HR at most study time intervals. Internalizing symptoms were positively correlated with HR and self-reported stress reactivity.
Stress reactivity, as reflected in both self-reported and HR responses to laboratory stressors, is related to the presence of both RAP and anxiety in children.
研究复发性腹痛（RAP）、焦虑症患儿与健康对照组在应对压力时的心率（HR）反应。
将临床样本（RAP 患儿和焦虑症患儿）与对照组儿童在自我报告和对压力的 HR 反应以及疼痛耐受力和强度的实验室测试（冷加压）方面进行比较。
与健康对照组相比，临床样本中的儿童在实验室任务前后的 HR 均升高。自我报告的社交压力应激反应与所有研究时间间隔的 HR 呈正相关。应对社交压力的二级控制与大多数研究时间间隔的 HR 呈负相关。内省症状与 HR 和自我报告的应激反应呈正相关。
应激反应，如实验室应激源的自我报告和 HR 反应所反映的那样，与儿童中 RAP 和焦虑症的存在有关。
