早期母婴互动，一个潜在的主要贡献者的早产儿的行为和生理调节的发展，很少受到研究的关注。本研究探讨了43名早产儿从分娩责任转移到母亲到每个婴儿的第4个月的生理调节的发展与母婴喂养相互作用。婴儿和母亲在出院前在特殊护理托儿所和产后1个月和4个月在家中观察。一般线性混合模型被用来检查婴儿心率变异性（HRV）和积极情感参与和敏感性/反应性分数随时间的变化和婴儿HRV喂养条件（喂养前，喂养，喂养后）。随着时间的推移，高频和低频HRV存在显著差异（分别为p <0.001和p = 0.014）。然而，母亲的喂养行为并没有表现出显着的影响的时间（p = 0.24）。喂养条件对高频HRV的影响是显著的（p <0.001），与喂养前和喂养后相比，喂养期间的HRV较低。母亲的喂养行为与此无关。婴儿HRV发现母亲喂养行为对婴儿生理调节的影响可能需要研究HRV与婴儿喂养行为的关系。
Early mother-infant interaction, a potentially major contributor to the development of a premature infant's behavioral and physiologic regulation, has received very little research attention. This study examined the development of physiologic regulation in relation to maternal-infant feeding interaction for 43 premature infants, from the time caregiving responsibility was transferred to the mother through each infant's 4th postterm month. Infants and mothers were seen in a special care nursery just before discharge and in home at 1 and 4 months postterm age. General linear mixed models were used to examine the changes in infant heart rate variability (HRV) and Positive Affective Involvement and Sensitivity/Responsiveness scores over time and infant HRV over feeding conditions (prefeeding, feeding, and postfeeding). Significant differences were found for high-frequency and low-frequency HRV over time (p < .001 and p = .014, respectively). However, maternal feeding behavior did not show a significant effect of time (p = .24). The feeding condition effect on high-frequency HRV was significant (p < .001), with HRV lower during feeding compared to both prefeeding and postfeeding. Maternal feeding behavior was not associated with. infant HRV Discovering the ways in which maternal feeding behavior contributes to infant physiologic regulation may require study of the relationship of HRV to infant feeding behavior.
