背景：母亲产前应激与婴儿负性情绪有关。然而，尚不清楚产妇产前压力的不同来源，如抑郁、焦虑和妊娠特异性焦虑症状如何与反应性结果相关。本研究旨在测试不同来源的母亲产前压力和婴儿在六个月的情绪反应之间的关系。方法：我们的研究人群（n=282）来自FinnBrain出生队列研究。产前压力通过在妊娠期间三个时间点的母亲抑郁、一般焦虑和妊娠特异性焦虑问卷来测量（gwk 14,24,34）。根据症状评分，将样本分为怀孕期间压力高的母亲（n=110）和怀孕期间压力低的母亲（n=172）。母亲报告的婴儿情绪反应及其分量表在产后6个月测量。结果：在控制背景变量和产妇产后症状后，仅用妊娠特异性焦虑预测总体负性情绪反应（β =0.20, p < 0.01）、恐惧（β =0.15, p = 0.057）和坠落反应（β =-0.22, p < 0.01）。调整混杂因素后，未发现婴儿阳性反应的显著预测因子。局限性：使用了母亲对母亲症状和婴儿反应性的报告，这可能会增加报告偏倚的风险。结论：研究结果表明，在怀孕期间经历压力的母亲应该得到干预，筛查应该特别关注与怀孕有关的担忧。(C) 2016 Elsevier B.V.版权所有
Background: Maternal prenatal stress has been related to infant negative affect. However, it is still unclear how different sources of maternal prenatal stress such as depressive, anxiety and pregnancy-specific anxiety symptoms are associated with reactivity outcomes. This study aimed to test the associations between different sources of maternal prenatal stress and the aspects of infant emotional reactivity at six months.Method: Our study population (n=282) was drawn from the FinnBrain Birth Cohort Study. Prenatal stress was measured by questionnaires on maternal depression, general anxiety and pregnancy-specific anxiety at three time points across pregnancy (gwk 14, 24, 34). Based on the symptom scores, the sample was divided into mothers with high stress during pregnancy (n=110) and mothers with low stress during pregnancy (n=172). Mother-reported infant emotional reactivity and its subscales were measured six months postpartum.Results: After controlling for background variables and maternal postnatal symptoms, overall negative emotional reactivity (beta=0.20, p < 0.01), and its aspects fearfulness (beta=0.15, p =.057) and falling reactivity (beta=-0.22, p < 0.01), were predicted by only pregnancy-specific anxiety. No significant predictors were found for infant positive reactivity after adjusting for confounders.Limitations: Mother reports of both maternal symptoms and infant reactivity were used, which might increase the risk of reporting bias. Conclusions: The findings suggest that mothers experiencing stress should be provided intervention during pregnancy, and that screening should have a particular focus on pregnancy-related worries.
