The role of the hypothalamic-pituitary-adrenal (HPA) axis in psychiatric disorders following trauma is poorly studied and most studies have been done on adults.
To investigate the association of mental well-being and diurnal cortisol in abused adolescents.
The present cross-sectional study examined diurnal salivary cortisol (measured three times a day during three days) in relation to psychiatric symptoms (Trauma Symptoms Checklist for Children) and the salutogenic construct "sense of coherence", in 15 adolescents exposed to childhood abuse.
Significant correlations were found between symptoms and sense of coherence versus early and late morning cortisol concentrations. The correlations were most consistent for internalizing and externalizing symptoms, and somewhat less for post-traumatic symptoms and sense of coherence. In contrast, evening cortisol did not correlate with any of the psychological measures.
These results extend previous research findings by pointing towards a relation between symptoms and higher morning cortisol and accentuated diurnal cortisol variation in abused adolescent as opposed to lower basal cortisol and a flattening of the cortisol rhythm repeatedly observed in traumatized adults.
The pathophysiology of the impact of trauma on youth, including the impact on biological stress systems, are important for an understanding of the consequences of trauma and may serve as a basis for the development of new treatment options.
下丘脑-垂体-肾上腺(HPA)轴在创伤后精神障碍中的作用研究较少,且大多数研究是在成年人中进行的。
调查受虐待青少年的心理健康与昼夜皮质醇之间的关联。
本横断面研究检测了15名遭受童年虐待的青少年的昼夜唾液皮质醇(在三天内每天测量三次),并将其与精神症状(儿童创伤症状清单)和健康生成概念“连贯感”进行关联分析。
症状及连贯感与清晨和傍晚的皮质醇浓度之间存在显著相关性。内化和外化症状的相关性最为一致,创伤后症状和连贯感的相关性则稍弱。相比之下,傍晚皮质醇与任何心理测量指标均无相关性。
这些结果扩展了先前的研究发现,表明受虐待青少年的症状与较高的清晨皮质醇以及加剧的昼夜皮质醇变化有关,这与创伤后成年人反复观察到的较低基础皮质醇和皮质醇节律变平相反。
创伤对青少年影响的病理生理学,包括对生物应激系统的影响,对于理解创伤后果很重要,可能为开发新的治疗方案提供依据。
