The evidence for negative influences of maternal stress during pregnancy on child cognition remains inconclusive. This study tested the association between maternal prenatal stress and child intelligence in 4,251 mother-child dyads from a multiethnic population-based cohort in the Netherlands. A latent factor of prenatal stress was constructed, and child IQ was tested at age 6 years. In Dutch and Caribbean participants, prenatal stress was not associated with child IQ after adjustment for maternal IQ and socioeconomic status. In other ethnicities no association was found; only in the Moroccan/Turkish group a small negative association between prenatal stress and child IQ was observed. These results suggest that prenatal stress does not predict child IQ, except in children from less acculturated minority groups.
母亲在孕期所承受的压力对儿童认知能力的负面影响的证据尚无定论。本研究在荷兰一个基于多民族的队列中，对 4251 对母婴对子进行了研究，检验了母亲产前压力与儿童智力之间的关系。研究构建了一个产前压力的潜在因素，并在儿童 6 岁时测试了他们的智商。在荷兰和加勒比参与者中，调整了母亲的智商和社会经济地位后，产前压力与儿童的智商没有关联。在其他种族中没有发现关联；只有在摩洛哥/土耳其群体中，观察到产前压力与儿童智商之间存在较小的负相关。这些结果表明，产前压力并不能预测儿童的智商，除了在文化程度较低的少数族裔儿童中。
