There is limited understanding of factors across the lifespan that influence pregnant women's respiratory sinus arrhythmia (RSA), which could have implications for their health and offspring development. We examined associations among 162 English- and Spanish-speaking pregnant women's childhood maltreatment history, emotion dysregulation, recent life stress, and resting RSA during the third trimester. Moderated mediation analyses indicated that more severe childhood maltreatment history (95% confidence interval (CI) [0.26, 0.63]) and higher emotion dysregulation (95% CI [0.001, 0.006]) predicted more stress during pregnancy, and childhood maltreatment history interacted with emotion dysregulation to predict resting RSA (95% CI [−0.04, −0.0003]). Exploratory analyses revealed that women's health-related stress during pregnancy mediated the relation between emotion dysregulation and RSA regardless of childhood maltreatment severity (95% CI [−0.007, −0.002]). These findings suggest that women's resting RSA during pregnancy may reflect physical and emotional stress accumulation across the lifespan and that relations between early life adversity and prenatal psychophysiology may be buffered by protective factors, such as emotion regulation. In addition, these findings underscore the importance of distinguishing between types of prenatal stress. Given the implications for women's health and offspring development, we urge researchers to continue exploring factors associated with pregnant women's psychophysiology.

一生中逆境对妊娠期呼吸性窦性心律失常的影响

对影响孕妇呼吸性窦性心律失常 (RSA) 的整个生命周期的因素了解有限，这可能对她们的健康和后代发育产生影响。我们检查了 162 名讲英语和西班牙语的孕妇的童年虐待史、情绪失调、近期生活压力和妊娠晚期静息 RSA 之间的关联。适度的中介分析表明，更严重的童年虐待史（95% 置信区间 (CI) [0.26, 0.63]）和更高的情绪失调（95% CI [0.001, 0.006]）预示着怀孕期间的压力更大，而童年虐待史与情绪失调以预测静息 RSA (95% CI [-0.04, -0.0003])。探索性分析表明，女性 怀孕期间与健康相关的压力介导了情绪失调和 RSA 之间的关系，而与童年虐待的严重程度无关（95% CI [-0.007, -0.002]）。这些研究结果表明，女性在怀孕期间的静息 RSA 可能反映了整个生命周期中身体和情绪压力的积累，并且早期生活逆境与产前心理生理学之间的关系可能会受到情绪调节等保护性因素的缓冲。此外，这些发现强调了区分产前压力类型的重要性。鉴于对女性健康和后代发育的影响，我们敦促研究人员继续探索与孕妇心理生理学相关的因素。-0.002]）。这些研究结果表明，女性在怀孕期间的静息 RSA 可能反映了整个生命周期中身体和情绪压力的积累，并且早期生活逆境与产前心理生理学之间的关系可能会受到情绪调节等保护性因素的缓冲。此外，这些发现强调了区分产前压力类型的重要性。鉴于对女性健康和后代发育的影响，我们敦促研究人员继续探索与孕妇心理生理学相关的因素。-0.002]）。这些研究结果表明，女性在怀孕期间的静息 RSA 可能反映了整个生命周期中身体和情绪压力的积累，并且早期生活逆境与产前心理生理学之间的关系可能会受到情绪调节等保护性因素的缓冲。此外，这些发现强调了区分产前压力类型的重要性。鉴于对女性健康和后代发育的影响，我们敦促研究人员继续探索与孕妇心理生理学相关的因素。比如情绪调节。此外，这些发现强调了区分产前压力类型的重要性。鉴于对女性健康和后代发育的影响，我们敦促研究人员继续探索与孕妇心理生理学相关的因素。比如情绪调节。此外，这些发现强调了区分产前压力类型的重要性。鉴于对女性健康和后代发育的影响，我们敦促研究人员继续探索与孕妇心理生理学相关的因素。
