To determine the reliability of bioelectrical impedance analysis, and to compare and contrast the anthropometric and BIA status of newborns.
BIA and anthropometric parameters were compared in the few days after birth and at about 3 weeks of age.
At the maternity hospital or in a paediatric care unit.
Small- or appropriate-for-gestational-age newborns, with birth weight below or above the 10th percentile of the reference value, respectively. Measurements were performed on 36 and 47 newborns at birth, and for a subgroup (21 and 11) again about 3 weeks later, respectively.
At birth, length2/resistance was 4.3 +/- 0.6 and 6.1 +/- 1.2 cm2/omega (P = 10(-7)), and at 3 weeks of age length2/resistance was 5.0 +/- 0.6 and 5.7 +/- 0.8 cm2/omega (P = 0.11), for small- and appropriate-for-gestational-age newborns, respectively. Percentage reliability was 2.2% and 2.6% for intra- and inter-observer measurements of resistance. Importance of a correct placement of the sensor electrode was demonstrated.
Ease of measurement and reliability of BIA in neonates were shown. Evolution of BIA values is in agreement with the known increase in total body water linked to regrowth of cell mass in small-for-gestational-age infants. Additional study is required before BIA should be used in usual clinical setting in newborns due to the lack of prediction equation.
确定生物电阻抗分析的可靠性，并比较和对比新生儿的人体测量学和生物电阻抗分析状况。
在出生后几天内以及约3周龄时对生物电阻抗分析和人体测量学参数进行比较。
在妇产医院或儿科护理病房。
小于胎龄儿或适于胎龄儿，出生体重分别低于或高于参考值的第10百分位数。分别在36名和47名新生儿出生时进行测量，并对一个亚组（分别为21名和11名）在约3周后再次进行测量。
出生时，小于胎龄儿和适于胎龄儿的身长²/电阻分别为4.3±0.6和6.1±1.2 cm²/Ω（P = 10⁻⁷），3周龄时身长²/电阻分别为5.0±0.6和5.7±0.8 cm²/Ω（P = 0.11）。电阻测量的观察者内和观察者间可靠性百分比分别为2.2%和2.6%。证明了传感器电极正确放置的重要性。
显示了新生儿生物电阻抗分析测量的简便性和可靠性。生物电阻抗分析值的变化与已知的小于胎龄儿细胞质量再生导致的总体水增加一致。由于缺乏预测方程，在新生儿常规临床环境中使用生物电阻抗分析之前还需要进一步研究。
