Preterm neonates show decreased HRV compared to those at full-term. We compared HRV metrics between preterm and full-term neonates in transfer periods from neonate rest state to neonate-parent interaction, and vice versa.
Short-term recordings of the HRV parameters (time and frequency-domain indices and non-linear measurements) of 28 premature healthy neonates were compared with the metrics of 18 full-term neonates. HRV recordings were performed at home at term-equivalent age and HRV metrics were compared between the following transfer periods: from first rest state of the neonate (TI1) to a period in which the neonate interacted with the first parent (TI2), from TI2 to a second neonate rest state (TI3), and from TI3 to a period of neonate interaction with the second parent (TI4).
For the whole HRV recording period, PNN50, NN50 and HF (%) was lower for preterm neonates compared to full-terms. These findings support the reduced parasympathetic activity of preterm compared to full-term neonates. The results of comparisons between transfer period simply a common coactivation of SNS and PNS systems for both full and pre-term neonates.
Spontaneous interaction with the parent may reinforce both full and pre-term neonates' ANS maturation.
与足月儿相比，早产儿的心率变异性（HRV）降低。我们比较了早产儿和足月儿在从新生儿静息状态到新生儿与父母互动期间以及反之的转换阶段的HRV指标。
将28例健康早产儿的HRV参数（时域和频域指标以及非线性测量）的短期记录与18例足月儿的指标进行比较。在足月等效年龄时在家中进行HRV记录，并在以下转换阶段比较HRV指标：从新生儿的第一个静息状态（TI1）到新生儿与第一位父母互动的阶段（TI2），从TI2到新生儿的第二个静息状态（TI3），以及从TI3到新生儿与第二位父母互动的阶段（TI4）。
在整个HRV记录期间，与足月儿相比，早产儿的PNN50、NN50和HF（%）较低。这些发现支持了与足月儿相比早产儿副交感神经活动降低。转换阶段之间比较的结果仅仅表明足月和早产儿的交感神经系统和副交感神经系统存在共同激活。
与父母的自发互动可能会加强足月和早产儿自主神经系统的成熟。
