目前对影响孕妇呼吸窦性心律失常（RSA）的因素的了解有限，这可能对她们的健康和后代的发育有影响。我们研究了162名说英语和西班牙语的孕妇的童年虐待史、情绪失调、最近的生活压力和妊娠晚期休息时的RSA之间的关系。有调节的中介分析表明，更严重的儿童虐待史（95%置信区间[0.26,0.63]）和更严重的情绪失调（95% CI[0.001, 0.006]）预测怀孕期间更多的压力，儿童虐待史与情绪失调相互作用预测休息时的RSA （95% CI[- 0.04, - 0.0003]）。探索性分析显示，无论儿童虐待严重程度如何，怀孕期间女性健康相关压力介导了情绪失调和RSA之间的关系（95% CI[−0.007,−0.002]）。这些发现表明，女性在怀孕期间的休息RSA可能反映了整个生命周期中身体和情绪压力的积累，而早期生活逆境和产前心理生理之间的关系可能被情绪调节等保护因素所缓冲。此外，这些发现强调了区分产前压力类型的重要性。鉴于对妇女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相关的因素。
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.
