慢性压力对前额叶的功能有有害的影响。经验证据表明，心率变异性（HRV）升高的迷走神经张力可以减轻精神压力对额叶功能的影响。本研究通过信息处理速度（DSST）、单词流畅性和言语学习任务表现来评估HRV对压力相关认知能力下降的缓解作用。分析来自西班牙裔社区健康研究/拉丁裔研究（HCHS/SOL）社会文化辅助项目的1420名西班牙裔/拉丁裔成年人的无伪影心电图（ECG）数据。使用12导联心电图收集所有正常r -峰至r -峰间期（RMSSD）连续差的均方根的短期记录，以及相邻拍次之间的变化和这些间隔的标准差（SDNN）作为总HRV的指标。正如预测的那样，HRV和任务上的压力出现了相互作用，这些任务被认为需要最大的前额叶参与，即DSST。在考虑了社会人口因素后，慢性压力与SDNN高四分位数的个体的更好的DSST表现有关，但与RMSSD无关。更大的压力暴露对DSST表现的矛盾效应可能部分地解释为高压力队列中经常报道的信息处理和决策速度的增加。这种相互作用的本质突出了通过迷走神经张力谱来研究压力和认知之间关系的重要性。
Chronic stress has a deleterious effect on prefrontal lobe functioning. Empirical evidence suggests elevated vagal tone, indexed by elevated heart rate variability (HRV), mitigates the effect of mental stress on frontal lobe function. Here, the mitigating effect of HRV on stress-related decrements in cognitive performance is assessed based on information processing speed (DSST), word fluency and verbal learning task performance. Artifact free electrocardiogram (ECG) data was analyzed from 1420 Hispanic/Latino adults from the Sociocultural Ancillary of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). A 12-lead ECG was used to collect shortterm recordings of the root mean square of successive differences in all normal R-peak to R-peak intervals (RMSSD) and the change between adjacent beats and the standard deviation of those intervals (SDNN) as indices of total HRV. As predicted, an interaction emerged for HRV and stress on the task presumed to require the greatest prefrontal lobe involvement, i.e., the DSST. After accounting for sociodemographic factors, chronic stress was associated with better DSST performance amongst individuals at higher quartile of SDNN, but not RMSSD. The paradoxical effect for greater stress exposure on DSST performance may in part be explained by increased speed of information processing and decision making often reported in high-stress cohorts. The nature of this interaction highlights the importance of examining the relationship between stress and cognition across a spectrum of vagal tone.
