To examine possible relations between parents' psychological stress and children's saliva cortisol levels in connection with a mild stressor (drawing a blood sample).
Parenting stress and serious life events at birth, age 1, age 2, age 5, and age 8 were assessed. Eighty-two paired saliva samples collected from their 8-year-old children just before and 30 min after blood was drawn were analyzed.
Instead of increasing, cortisol levels significantly decreased. Repeated measures GLM indicated a significant relation between higher parenting stress at child age 1 and at age 8, and elevated cortisol levels. A t-test indicated that cortisol levels after the blood draw were significantly higher in children whose parents reported a serious life event at age 8.
Parenting stress could be a relevant factor for children's adjustment of the HPA axis with long-term effects and leave children more vulnerable to experiences of stress.
探讨父母心理压力与儿童唾液皮质醇水平在轻度应激源（采血）下的可能关系。
评估育儿压力和出生时、1 岁、2 岁、5 岁和 8 岁时的严重生活事件。分析了 82 对 8 岁儿童在采血前和采血后 30 分钟采集的唾液样本。
皮质醇水平并没有升高，反而显著下降。重复测量 GLM 表明，儿童 1 岁和 8 岁时的育儿压力与皮质醇水平升高呈显著相关。t 检验表明，父母报告 8 岁时发生严重生活事件的儿童，采血后皮质醇水平显著升高。
育儿压力可能是儿童 HPA 轴调节的一个相关因素，具有长期影响，使儿童更容易受到压力体验的影响。
