A longitudinal study of a sample of women and their offspring from two urban areas (N = 233) was conducted to test whether maternal prenatal anxiety trajectories from early to late pregnancy are associated with 12-month infant developmental outcomes, independent of maternal postpartum anxiety symptoms, prenatal and postpartum depressive symptoms, parity, birth outcomes and maternal education. Three types of maternal anxiety trajectories over the course of pregnancy were identified and labeled increasing, decreasing, and stable-low. Only increasing maternal prenatal anxiety was associated with 12-month infant outcomes, specifically lower Bayley-III scores on receptive language and gross motor skills. Maternal anxiety measured at each individual timepoint in pregnancy was not associated with infant Bayley-III outcomes, highlighting the importance of examining trajectories of maternal affect.
本研究对来自两个城市地区的女性及其后代（N=233）进行了纵向研究，以测试从妊娠早期到晚期的母体产前焦虑轨迹是否与 12 个月大婴儿的发育结果相关，而与母亲产后焦虑症状、产前和产后抑郁症状、产次、出生结局和母亲教育无关。在妊娠过程中确定了三种类型的母体焦虑轨迹，并分别标记为增加型、降低型和稳定-低型。只有产前焦虑增加的母亲与 12 个月大婴儿的结果有关，具体表现为接受性语言和大运动技能的贝利 III 评分较低。在妊娠的每个单独时间点测量的母体焦虑与婴儿贝利 III 结果无关，这突出表明检查母体情感轨迹的重要性。
