很少有研究调查母亲一生的创伤暴露对婴儿气质的影响。我们研究了母亲创伤史与婴儿负面情绪之间的关系，并通过产前皮质醇暴露在社会人口统计学不同的母婴双体样本中进行了修改。在怀孕期间，母亲们完成了终生创伤暴露和当前压力源的测量。通过母体毛发评估妊娠晚期皮质醇分泌量。当婴儿6个月大时，母亲完成婴儿行为问卷-修订。在控制婴儿性别和母亲年龄、教育程度、种族/民族和怀孕期间压力的分析中，母亲创伤暴露程度越高，婴儿对限制和悲伤的痛苦程度越高。较高和较低的产前皮质醇暴露改变了母亲创伤史与婴儿觉醒恢复率之间关系的大小和方向。在暴露于较高水平产前皮质醇的婴儿中，母亲创伤史和婴儿对限制的痛苦之间的关联更强。分析表明，母亲一生的创伤暴露与婴儿负面情绪的几个领域相关，独立于怀孕期间母亲的压力暴露，其中一些关联可能被产前皮质醇暴露所改变。研究结果对理解创伤暴露对儿童发育结果的代际影响具有启示意义。
Little research has examined the impact of maternal lifetime trauma exposure on infant temperament. We examined associations between maternal trauma history and infant negative affectivity and modification by prenatal cortisol exposure in a sociodemographically diverse sample of mother–infant dyads. During pregnancy, mothers completed measures of lifetime trauma exposure and current stressors. Third-trimester cortisol output was assessed from maternal hair. When infants were 6 months old, mothers completed the Infant Behavior Questionnaire-Revised. In analyses that controlled for infant sex and maternal age, education, race/ethnicity, and stress during pregnancy, greater maternal trauma exposure was associated with increased infant distress to limitations and sadness. Higher and lower prenatal cortisol exposure modified the magnitude and direction of association between maternal trauma history and infant rate of recovery from arousal. The association between maternal trauma history and infant distress to limitations was somewhat stronger among infants exposed to higher levels of prenatal cortisol. The analyses suggested that maternal lifetime trauma exposure is associated with several domains of infant negative affectivity independently of maternal stress exposures during pregnancy and that some of these associations may be modified by prenatal cortisol exposure. The findings have implications for understanding the intergenerational impact of trauma exposure on child developmental outcomes.
