This study examined relationships among stress hormone levels, posttraumatic stress disorder (PTSD) diagnosis and symptoms, and gender shortly after a common civilian trauma.
Levels of catecholamines and cortisol in 15-hour urine samples were examined in 55 adults who had been in serious motor vehicle accidents and in 22 age-matched control.
Catecholamines were related to PTSD diagnosis and symptoms, but only among men: PTSD-symptomatic men who had been in an accident exhibited elevated levels of epinephrine and norepinephrine 1 month after the accident and had higher epinephrine levels 5 months later. Intrusive thoughts predicted catecholamine levels at 1 month, and avoidance of trauma-relevant stimuli was associated with higher epinephrine levels 5 months later. These effects were not significant among women. Urinary cortisol was also elevated among PTSD-symptomatic men, but not women, and only immediately (1 month) after the accident. For men and women, greater emotional numbing predicted a lower cortisol level 6 months after the accident.
These findings were interpreted as limited support for the generalizability of findings in men with chronic, combat-related PTSD and indicate the need for additional research on psychoendocrine assessment of traumatized women and specific dimensions of PTSD symptomatology.
本研究调查了常见平民创伤后不久,应激激素水平、创伤后应激障碍(PTSD)诊断及症状与性别的关系。
对55名遭遇严重机动车事故的成年人及22名年龄匹配的对照者的15小时尿液样本中的儿茶酚胺和皮质醇水平进行检测。
儿茶酚胺与PTSD诊断及症状相关,但仅在男性中如此:事故后1个月,有PTSD症状的男性事故受害者肾上腺素和去甲肾上腺素水平升高,5个月后肾上腺素水平更高。闯入性思维可预测1个月时的儿茶酚胺水平,而回避与创伤相关的刺激与5个月后更高的肾上腺素水平相关。这些效应在女性中不显著。有PTSD症状的男性尿液皮质醇水平也升高,但女性未升高,且仅在事故后立即(1个月)升高。对于男性和女性,情感麻木程度越高预示事故后6个月皮质醇水平越低。
这些发现被解释为对患有慢性、与战斗相关PTSD的男性研究结果的普遍性提供了有限支持,并表明需要对受创伤女性的心理内分泌评估及PTSD症状的特定维度进行更多研究。
