Polyvagal theory has influenced research on the role of cardiac vagal control, indexed by respiratory sinus arrhythmia withdrawal (RSA-W) during challenging states, in children's self-regulation. However, it remains unclear how well RSA-W predicts adaptive functioning (AF) outcomes and whether certain caveats of measuring RSA (e.g., respiration) significantly impact these associations. A meta-analysis of 44 studies (n=4996 children) revealed small effect sizes such that greater levels of RSA-W were related to fewer externalizing, internalizing, and cognitive/academic problems. In contrast, RSA-W was differentially related to children's social problems according to sample type (community vs. clinical/at-risk). The relations between RSA-W and children's AF outcomes were stronger among studies that co-varied baseline RSA and in Caucasian children (no effect was found for respiration). Children from clinical/at-risk samples displayed lower levels of baseline RSA and RSA-W compared to children from community samples. Theoretical/practical implications for the study of cardiac vagal control are discussed.
躯体自主神经理论影响了对心脏迷走神经控制作用的研究,该作用通过在挑战性状态下的呼吸窦性心律失常退缩(RSA-W)来评估,这与儿童的自我调节有关。然而,目前尚不清楚 RSA-W 对适应性功能(AF)结果的预测能力如何,以及测量 RSA 时的某些注意事项(例如呼吸)是否会显著影响这些关联。对 44 项研究(n=4996 名儿童)的荟萃分析显示,RSA-W 水平与较少的外化、内化和认知/学术问题相关,这表明其效应较小。相比之下,根据样本类型(社区与临床/高危),RSA-W 与儿童社交问题的关系存在差异。在共同变基线 RSA 的研究中,以及在白种人儿童中,RSA-W 与儿童的 AF 结果之间的关系更强(呼吸则没有发现效果)。与来自社区样本的儿童相比,来自临床/高危样本的儿童的基线 RSA 和 RSA-W 水平较低。讨论了躯体自主神经控制研究的理论/实践意义。
