Research shows that prenatal maternal stress (PNMS) negatively affects a range of infant outcomes; yet no single study has explored the effects of stress in pregnancy from a natural disaster on multiple aspects of infant neurodevelopment. This study examined the effects of flood-related stress in pregnancy on 6-month-olds' neurodevelopment and examined the moderating effects of timing of the stressor in gestation and infant sex on these outcomes. Women exposed to the 2011 Queensland (Australia) floods in pregnancy completed surveys on their flood-related objective and subjective experiences at recruitment and reported on their infants' neurodevelopment on the problem solving, communication, and personal-social scales of the Ages and Stages-III at 6 months postpartum (N = 115). Interaction results showed that subjective flood stress in pregnancy had significantly different effects in boys and girls, and that at high levels of stress girls had significantly lower problem solving scores than boys. Timing of the flood later in pregnancy predicted lower personal-social scores in the sample, and there was a trend (p < .10) for greater objective flood exposure to predict lower scores. PNMS had no effect on infants' communication skills. In conclusion, differential aspects of maternal flood-related stress in pregnancy influenced aspects of 6-month-olds' neurodevelopment.
研究表明，产前母亲压力（PNMS）会对一系列婴儿结局产生负面影响；然而，尚无单一研究从自然灾害导致的孕期压力方面，探讨其对婴儿神经发育多个方面的影响。本研究考察了孕期与洪水相关的压力对6个月大婴儿神经发育的影响，并考察了应激源在孕期的发生时间以及婴儿性别对这些结局的调节作用。孕期经历2011年澳大利亚昆士兰州洪水的女性在招募时完成了关于其与洪水相关的客观和主观经历的调查，并在产后6个月时报告了其婴儿在《年龄与阶段问卷第三版》的问题解决、沟通和个人社交量表上的神经发育情况（N = 115）。交互作用结果显示，孕期主观洪水压力对男孩和女孩的影响存在显著差异，在高压力水平下，女孩的问题解决得分显著低于男孩。孕期后期发生洪水预示着样本中较低的个人社交得分，且存在一种趋势（p <.10），即更高的客观洪水暴露预示着更低的得分。产前母亲压力对婴儿的沟通技能没有影响。总之，孕期母亲与洪水相关压力的不同方面影响了6个月大婴儿神经发育的各个方面。
