识别最容易受到消极和积极社会环境影响的婴儿对于理解早期行为发展至关重要。本研究纵向评估了婴儿迷走神经张力（呼吸性窦性心律失常; RSA）和母亲的社会支持对322个低收入墨西哥裔美国人的母亲-婴儿二人组（婴儿：54.1%女性）的行为问题和能力的相互影响，并探讨了性别差异。根据6周龄时的静息HR数据计算婴儿RSA。母亲在6个月时报告了一般社会支持、伴侣支持和家庭支持，在1岁时报告了婴儿行为问题和能力。双向互动（RSA ×支持来源）进行了评估，以预测行为问题和能力，调整协变量。结果表明，更高的能力与较低的RSA的母亲报告更高的一般支持或更高的合作伙伴的支持婴儿。母亲伴侣或家庭支持对RSA行为问题的交互作用仅在女婴中发现：当母亲报告低支持时，RSA较高的女孩表现出更多的行为问题，但在高支持的背景下，问题水平较低。我们的研究结果表明，婴儿RSA是早期社会环境对早期发展的影响的重要调节剂。
The identification of infants who are most susceptible to both negative and positive social environments is critical for understanding early behavioral development. This study longitudinally assessed the interactive effects of infant vagal tone (respiratory sinus arrhythmia; RSA) and maternal social support on behavioral problems and competence among 322 low-income Mexican American mother–infant dyads (infants: 54.1% female) and explored sex differences. Infant RSA was calculated from resting HR data at 6 weeks of age. Mothers reported on general social support, partner support, and family support at 6 months, and infant behavioral problems and competence at 1 year. Two-way interactions (RSA × support source) were evaluated to predict behavioral problems and competence, adjusting for covariates. Results indicated higher competence among infants with lower RSA whose mothers reported higher general support or higher partner support. Interactive effects on behavior problems of RSA with maternal partner or family support were only found for female infants: Girls with higher RSA showed more behavior problems when mothers reported low support, but fewer problem levels in the context of high support. Our results suggest that infant RSA is an important moderator of the effects of the early social environment on early development.
