目的早产儿，特别是早产儿(胎龄32周)，存在生长发育不良和神经发育不良的风险。早产儿的不良生长和神经发育结果部分归因于新生儿重症监护病房(NICU)的厌恶声音和相对缺乏言语。在NICU中直接将早产儿暴露于语音中的实验研究发现，与神经发育相关的健康因素有显著改善。很少有研究检验NICU语言环境的自然变化是否与早产儿的短期健康结果有关。这些数据对于优化NICU的声环境非常重要。我们的目标是检查新生儿重症监护病房的语言环境与住院期间体重增加的关系。研究设计受试者为早产儿(n= ，20例)。每个婴儿在月经后32至36周时，使用自动语音计数设备评估其语音环境。确定同一时期的平均增重率(g/kg/d)。卡路里来自图表上的摄入量(大卡/公斤/天)。线性回归检验了卡路里摄入量和言语次数作为婴儿体重增加的预测因子。结果卡路里摄入量和言语暴露显著地预测了婴儿体重增加，每个单独解释的方差约为27%(总计R2= 60.2%；p<； 0.001)。言语计数与家庭探视率、在孵化器中的时间或健康敏感度无关。结论虽然未来的研究应确定影响的因果关系和方向，但增加NICU中的言语暴露可能有利于身体发育。NICU护理计划应考虑增加演讲暴露的机会。关键点
ObjectiveChildren born preterm, especially those born very preterm (<32 weeks of gestational age [GA]) are at risk for poor growth and adverse neurodevelopmental outcomes. Adverse growth and neurodevelopmental outcomes in preterm children have been attributed, in part, to the aversive sounds and relative speech paucity of the neonatal intensive care unit (NICU). Experimental studies that directly expose preterm infants to speech sounds in the NICU find significant improvements in health factors relevant to neurodevelopment. Few studies have examined whether natural variations in the speech environment of the NICU are related to short-term health outcomes in preterm infants. Such data are important for optimizing the sound environment of the NICU. Our objective was to examine relations between the NICU speech environment and the rate of weight gain during hospitalization.Study DesignParticipants were infants born very preterm (n= 20). The speech environment of each infant was assessed at 32 to 36 weeks of postmenstrual age using an automatic speech-counting device. Average rates of weight gain (g/kg/d) were ascertained over the same period. Calories were derived from charted intake (kcals/kg/d). Linear regressions examined caloric intake and speech counts as predictors of infant weight gain.ResultsInfant weight gain was significantly predicted by caloric intake and speech exposure, each uniquely accounting for approximately 27% variance (totalR2= 60.2%;p< 0.001). Speech counts were uncorrelated with rates of family visitation, time in incubator, or health acuity.ConclusionWhile future research should establish causality and direction of effects, enhancing speech exposure in the NICU may be beneficial for physical growth. NICU care plans should consider opportunities to increase speech exposure.Key Points
