Childhood trauma is a non-specific risk factor for eating disorders (EDs). It has been suggested that this risk is exerted through trauma-induced long-lasting changes in the body stress response system. Therefore, we explored the activity of the hypothalamus-pituitary-adrenal axis and of the sympathetic nervous system in adult ED patients with or without a history of childhood trauma exposure. Salivary cortisol and alpha-amylase, a marker of the sympathetic nervous system activity, were measured at awakening and after 15, 30 and 60 min in 35 women with EDs. The Childhood Trauma Questionnaire (CTQ) was employed to assess exposure to childhood trauma and, according to the CTQ cut-off scores, 21 ED women were classified as maltreated (Mal) participants and 14 women as no-maltreated (noMal) ED participants. Compared to noMal ED women, Mal ED participants showed significantly decreased cortisol awakening response (between group difference: p = 0.0003) and morning salivary alpha-amylase secretion (between group difference: p = 0.02). Present results confirm that the cortisol awakening response of adult ED patients with childhood trauma exposure is lower than that of adult ED patients without childhood trauma experiences and show for the first time that also the morning secretion of salivary alpha-amylase is decreased in adult ED patients who have been exposed to early traumatic experiences. These results point for the first time to a dampening in the basal activity of both components of the endogenous stress response system in childhood maltreated adult ED women.

早期创伤经历会损害成人饮食失调内源性压力反应系统的两个组成部分的功能

童年创伤是饮食失调 (ED) 的非特异性风险因素。有人认为,这种风险是通过创伤引起的身体压力反应系统的长期变化而产生的。因此,我们探讨了有或没有儿童创伤暴露史的成人 ED 患者的下丘脑-垂体-肾上腺轴和交感神经系统的活动。35 名患有 ED 的女性在醒来时和 15、30 和 60 分钟后测量了唾液皮质醇和 α-淀粉酶(交感神经系统活动的标志物)。儿童创伤问卷 (CTQ) 用于评估儿童期创伤的暴露程度,根据 CTQ 截止分数,21 名 ED 女性被归类为受虐待 (Mal) 参与者,14 名女性被归类为未受虐待 (noMal) ED 参与者。与正常ED女性相比,Mal ED 参与者的皮质醇觉醒反应(组间差异:p = 0.0003)和早晨唾液α-淀粉酶分泌(组间差异:p = 0.02)显着降低。目前的结果证实,童年创伤暴露的成年 ED 患者的皮质醇觉醒反应低于没有童年创伤经历的成年 ED 患者,并首次表明成年 ED 患者的唾液α-淀粉酶的早晨分泌减少那些接触过早期创伤经历的人。这些结果首次表明,在儿童期受虐待的成年 ED 女性中,内源性应激反应系统的两个组成部分的基础活动都受到抑制。0003)和早晨唾液α-淀粉酶分泌(组间差异:p = 0.02)。目前的结果证实,童年创伤暴露的成年 ED 患者的皮质醇觉醒反应低于没有童年创伤经历的成年 ED 患者,并首次表明成年 ED 患者的唾液α-淀粉酶的早晨分泌减少那些接触过早期创伤经历的人。这些结果首次表明,在儿童期受虐待的成年 ED 女性中,内源性应激反应系统的两个组成部分的基础活动都受到抑制。0003)和早晨唾液α-淀粉酶分泌(组间差异:p = 0.02)。目前的结果证实,童年创伤暴露的成年 ED 患者的皮质醇觉醒反应低于没有童年创伤经历的成年 ED 患者,并首次表明成年 ED 患者的唾液α-淀粉酶的早晨分泌减少那些接触过早期创伤经历的人。这些结果首次表明,在儿童期受虐待的成年 ED 女性中,内源性应激反应系统的两个组成部分的基础活动都受到抑制。目前的结果证实,童年创伤暴露的成年 ED 患者的皮质醇觉醒反应低于没有童年创伤经历的成年 ED 患者,并首次表明成年 ED 患者的唾液α-淀粉酶的早晨分泌减少那些接触过早期创伤经历的人。这些结果首次表明,在儿童期受虐待的成年 ED 女性中,内源性应激反应系统的两个组成部分的基础活动都受到抑制。目前的结果证实,童年创伤暴露的成年 ED 患者的皮质醇觉醒反应低于没有童年创伤经历的成年 ED 患者,并首次表明成年 ED 患者的唾液α-淀粉酶的早晨分泌减少那些接触过早期创伤经历的人。这些结果首次表明,在儿童期受虐待的成年 ED 女性中,内源性应激反应系统的两个组成部分的基础活动都受到抑制。
