创伤对围产期母婴相互作用的影响可能会影响后代的生理系统参与健康结果的组织。本研究使用了一种新的先进的系统，最近适用于婴儿检查产妇一生的创伤和相关的心理症状，在围产期与婴儿的心肺反应性和行为困扰，在实验室应激源的协会。母亲自我报告一生中暴露于创伤，围产期创伤应激，以及目前的创伤后应激障碍（PTSD）和抑郁症的症状。在静态面部模式中，使用无创呼吸感应体积描记装置连续记录23名婴儿的心率和呼吸量、时间和胸腹协调指数，静态面部模式是一种录像的母婴二元评估，包括基线、应激源和恢复阶段。婴儿行为困扰过程中的程序也进行了评估。低暴露于创伤和围产期创伤应激的母亲的婴儿表现出预期的增加，从基线到应激源的行为困扰和心肺激活和减少这些参数从应激源到恢复。母亲暴露于多种创伤和围产期创伤应激升高的婴儿表现出类似的激活模式，从基线到应激源，但未能显示在恢复过程中减少。在控制了母亲目前的PTSD和抑郁症状后，这些模式得以维持。产妇一生的创伤暴露和创伤应激在围产期与中断婴儿心肺调节和行为困扰的压力协议。这些结果支持围产期规划的概念及其在身心健康结果中的潜在作用。
Trauma influences on perinatal maternal-child interactions may affect the organization of offspring physiological systems involved in health outcomes. This study used a novel advanced system recently adapted for infants to examine associations of maternal lifetime trauma and related psychological symptoms in the perinatal period with infant cardiorespiratory reactivity and behavioral distress in response to a laboratory stressor. Mothers self-reported lifetime exposure to trauma, perinatal traumatic stress, and current symptoms of posttraumatic stress disorder (PTSD) and depression. Heart rate and indices of respiratory volume, timing, and thoraco-abdominal coordination were continuously recorded using a non-invasive respiratory inductance plethysmography device from 23 infants during the Still-Face Paradigm, a videotaped mother-infant dyadic assessment that included baseline, stressor, and recovery phases. Infant behavioral distress during the procedure was also assessed. Infants of mothers with low exposure to trauma and perinatal traumatic stress showed expected increases in behavioral distress and cardiorespiratory activation from baseline to stressor and decreases in these parameters from stressor to recovery. Infants of mothers exposed to multiple traumas and with elevated perinatal traumatic stress showed similar patterns of activation from baseline to stressor but failed to show decreases during recovery. These patterns were maintained after controlling for current maternal PTSD and depressive symptoms. Maternal lifetime trauma exposure and traumatic stress during the perinatal period were associated with disrupted infant cardiorespiratory regulation and behavioral distress during a stressor protocol. These results support the concept of perinatal programming and its potential role in physical and mental health outcomes.
