项目摘要

DESCRIPTION (provided by applicant): The purpose of this longitudinal, descriptive study is to examine, for premature infants, patterns and mediators of heart rate variability (HRV) and adaptive feeding behavior through the first 4 post-term months. The study aims are to explore: (a) the pattern of change of infant HRV, infant adaptive feeding behavior, and mother adaptive feeding behavior just before discharge from the special-care nursery and at I and 4 months; (b) examine the mediating effect of the adaptiveness of mothers' feeding behavior on the contribution to HRV and to the adaptiveness of the infant's feeding behavior, of infant biologic condition, and mothers' depressive symptoms; and (c) explore the longitudinal effect of the adaptiveness of mothers' interactive feeding behavior on the adaptiveness of infant feeding behavior and HRV. A convenience sample of 64 premature infants and their mothers will participate in this study. A Holter monitor will be used to collect HRV data, which will be decomposed into parasympathetic components with spectral analysis. Videotaped feeding interactions will be analyzed using the Parent Child Early Relational Assessment. Mothers' depressive symptoms will be assessed with the Center for Epidemiological Studies- Depression Scale. Infant biologic condition will be estimated with the Neonatal Health Index. Regression analysis will be used to address the study aims.

描述（由申请人提供）：本纵向描述性研究的目的是检查早产儿在足月后前4个月的心率变异性（HRV）和适应性喂养行为的模式和介质。本研究旨在探讨：（a）婴儿离开特护托儿所前、1个月和4个月时婴儿心率变异性、婴儿适应性喂养行为和母亲适应性喂养行为的变化模式;（B）检查母亲喂养行为的适应性对心率变异性的贡献和对婴儿喂养行为的适应性、婴儿生物条件的中介作用，探讨母亲互动喂养行为的适应性对婴儿喂养行为的适应性和心率变异性的纵向影响。64名早产儿及其母亲的便利样本将参与本研究。将使用霍尔特监测仪收集HRV数据，并通过频谱分析将其分解为副交感神经成分。录像喂养互动将使用父母儿童早期关系评估进行分析。将使用流行病学研究中心-抑郁量表评估母亲的抑郁症状。将使用新生儿健康指数来估计婴儿的生物学状况。回归分析将用于解决研究目的。
