Resting respiratory sinus arrhythmia (RSA) may confer infant susceptibility to the postpartum environment. Among infants with higher RSA, there may be a positive relation between depressive symptoms across the first 6 months postpartum (PPD) and later behavior problems, and toddlers' dysregulation during mother-child interactions may partially explain the effects. Among a sample of low-income Mexican-American families, infant RSA (N = 322; 46% male) was assessed at 6 weeks of age; mothers (M = 27.8, SD = 6.5) reported PPD symptoms every 3 weeks from 6 to 24 weeks and infant behavior problems at 36 months. Dysregulation was observed at 24 months. PPD was positively associated with behavior problems only among infants with lower RSA; however, this relation was not mediated by dysregulation.
静息呼吸窦性心律失常(RSA)可能使婴儿易受产后环境影响。在 RSA 较高的婴儿中,产后第 6 个月(PPD)期间的抑郁症状与之后的行为问题之间可能存在正相关,而在母婴互动中婴儿的失调可能部分解释了这些影响。在一项针对低收入墨西哥裔美国家庭的样本中,在婴儿 6 周龄时评估其 RSA(N=322;46%为男性);母亲(M=27.8,SD=6.5)在 6 至 24 周期间每 3 周报告一次 PPD 症状,并在 36 个月时报告婴儿的行为问题。在 24 个月时观察到失调。只有在 RSA 较低的婴儿中,PPD 才与行为问题呈正相关;然而,这种关系不受失调的影响。
