To compare resting energy expenditure (REE) in small- and appropriate-for-gestational-age very low birth weight newborns after reaching corrected at-term age.
Observational study that included all clinically stable very low birth weight newborns admitted to a neonatal intensive care unit. The newborns were classified as small-for-gestational-age (SGA) and appropriate-for-gestational-age (AGA). Resting energy expenditure was measured using indirect calorimetry when the newborns reached at-term age.
A total of 51 newborns, of which 23 were SGA and 28 AGA, were included. There was no statistically significant difference in REE between the two groups, although the observed levels were higher than the reference values.
There is no statistical difference in resting expenditure energy between SGA and AGA infants when they reached term. The higher energy expenditure found in both groups may be explained by other factors related to prematurity and its complications and requires further investigation.
比较达到校正足月年龄后，小胎龄和适于胎龄的极低出生体重儿的静息能量消耗（REE）。
这是一项观察性研究，纳入了所有入住新生儿重症监护病房的临床稳定的极低出生体重儿。将新生儿分为小于胎龄儿（SGA）和适于胎龄儿（AGA）。当新生儿达到足月年龄时，使用间接测热法测量静息能量消耗。
共纳入 51 例新生儿，其中 23 例为 SGA，28 例为 AGA。两组之间的 REE 无统计学差异，尽管观察到的水平高于参考值。
当达到足月时，SGA 和 AGA 婴儿的静息能量消耗没有统计学差异。两组较高的能量消耗可能与与早产及其并发症相关的其他因素有关，需要进一步研究。
