产前社会心理暴露会显着影响婴儿的健康和发育。理论上，具有较高消极情绪的婴儿更容易受到环境暴露的影响。我们评估了产前母亲暴露与婴儿气质消极性的相互作用，以预测婴儿皮质醇对轻度挑战性母婴互动任务的反应。参与者包括 322 名墨西哥裔美国母婴二人组（母亲年龄 18-42 岁；82% 讲西班牙语；一般家庭收入 10,000-15,000 美元）。母亲们在产前报告了抑郁症状和社会支持，并在产后 6 周报告了婴儿气质消极。在 12 周母婴互动任务之前和之后收集婴儿的唾液皮质醇。较高的产前母亲抑郁症状和较低的社会支持预示着情绪消极性较高的婴儿皮质醇较高。较高的婴儿气质消极性预示着从产前到产后 12 周，母亲的痛苦会增加，社会支持会减少。母亲社会背景因素和婴儿气质的相互作用可能会影响婴儿神经生物学调节的发展，并随着时间的推移促进或紧张母亲和婴儿的适应。 (c) 2015 年 Wiley 期刊公司。
Prenatal psychosocial exposures can significantly affect infant health and development. Infants with higher temperamental negativity are theorized to be more susceptible to environmental exposures. We evaluated the interaction of prenatal maternal exposures and infant temperamental negativity to predict infant cortisol response to mildly challenging mother-infant interaction tasks. Participants included 322 Mexican American mother-infant dyads (mother age 18-42; 82% Spanish-speaking; modal family income $10,000-$15,000). Mothers reported depressive symptoms and social support prenatally and infant temperamental negativity at 6 weeks postpartum. Salivary cortisol was collected from infants before and after mother-infant interaction tasks at 12 weeks. Higher prenatal maternal depressive symptoms and lower social support predicted higher cortisol among infants with higher temperamental negativity. Higher infant temperamental negativity predicted an increase in maternal distress and a decrease in social support from prenatal to 12 weeks postpartum. Interactive influences of maternal social-contextual factors and infant temperament may influence the development of infant neurobiological regulation and promote or strain maternal and infant adaptation over time.
