Research indicates a higher prevalence of attention deficits in children exposed to HG in utero compared to controls with some claiming that the deficit is due to prenatal effects of malnutrition in HG mothers and others that it is due to maternal mental health after birth. The current study examines the effect of hyperemesis gravidarum (HG) diagnosis during pregnancy on infant attention controlling for maternal stress, depression anxiety and attachment. Thirty-eight infants mean age 4 months were videotaped with their mothers (19 mothers with a hyperemesis diagnosis and 19 controls) during play with a soft toy and looking at a picture book. Infant attention was operationalized as gaze direction towards the play activity, mother, and 'distracted' (indicated by looking away from play or mother). Mothers completed stress, depression, anxiety, and attachment questionnaires. HG exposed infants attended for significantly less time during play with a book or soft toy compared to controls. Maternal stress, depression, anxiety, and attachment did not differ in HG mothers and controls. Infant ability to attend to the toy, book, mother or being distracted did not relate to maternal postnatal attachment, or mental health. These results suggest that the prenatal environment, especially exposure to HG might be associated with reduced infant attention abilities independent of maternal postnatal health.
研究表明，与对照组相比，宫内暴露于 HG 的儿童注意力缺陷的患病率更高，一些人声称这种缺陷是由于 HG 母亲的营养不良对胎儿的影响，而另一些人则认为这是由于母亲产后的心理健康状况。本研究旨在探讨妊娠期间 HG 诊断对婴儿注意力的影响，同时控制母亲的压力、抑郁、焦虑和依恋。38 名婴儿（平均年龄 4 个月）与母亲一起（19 名母亲患有 HG，19 名对照组）在玩柔软玩具和看图画书时被录像。婴儿的注意力被定义为注视方向（指向玩耍活动、母亲或“分心”（表现为看向玩耍或母亲之外的地方）。母亲们完成了压力、抑郁、焦虑和依恋问卷。与对照组相比，HG 暴露组的婴儿在看书或玩柔软玩具时的注意力时间明显更短。HG 母亲和对照组的母亲在压力、抑郁、焦虑和依恋方面没有差异。婴儿对玩具、书、母亲或分心的注意力能力与母亲产后的依恋或心理健康无关。这些结果表明，产前环境，特别是暴露于 HG，可能与婴儿注意力能力下降有关，而与母亲产后的健康状况无关。
