This study examined the effect of HIV on visceromotor (i.e., heart rate and heart rate variability) and somatomotor (i.e., auditory processing and affect recognition) components of a Social Engagement System defined by the Polyvagal Theory (Porges, 1995) that links vagal regulation of the heart with brainstem regulation of the striated muscles of the face and head. Relative to at risk HIV-seronegative women, HIV-seropositive women had less heart rate variability (i.e., respiratory sinus arrhythmia) and had poorer performance on auditory processing and affect recognition tasks. CD4 was negatively correlated with the accuracy to detect specific emotions. The observed indices of atypical autonomic and behavioral regulation may contribute to greater difficulties in social behavior and social communication between HIV-infected women and other individuals in their social network.
本研究考察了 HIV 对社会参与系统的内脏运动（即心率和心率变异性）和躯体运动（即听觉处理和情感识别）成分的影响，该系统由多棘带理论（Porges, 1995）定义，将迷走神经调节心脏与脑干调节面部和头部的横纹肌联系起来。与有感染风险的 HIV 血清阴性女性相比，HIV 血清阳性女性的心率变异性（即呼吸窦性心律失常）较低，在听觉处理和情感识别任务上的表现较差。CD4 与检测特定情绪的准确性呈负相关。观察到的非典型自主和行为调节指标可能导致 HIV 感染女性与社交网络中的其他个体在社交行为和社交沟通方面存在更大困难。
