Although twin gestation is well recognized to be associated with impaired fetal and postnatal growth, specific data about body composition of twins in the first month of life are scarce.
The aim of this study was to compare the body composition of twins, evaluated with air-displacement plethysmography, to that of singletons of similar gestational age and adequacy of growth, during the first month of life. We tested the hypothesis that the quality of growth would be similar.
Anthropometric and air-displacement plethysmography measurements were performed in 18 pairs of twins and in 36 singleton neonates, longitudinally, from birth to the 30th day of life. Each twin was matched to a singleton infant of similar gestational age and birth weight z-score.
With regard to anthropometric measures, the only difference was a lower weight in twins versus singletons on the 15th day of life. With regard to body composition, we did not find any difference between groups at any time point. Fat mass increased significantly from day 1 to day 30 in both twins and singletons.
In terms of body composition, twins do not differ from singletons of similar gestational age and weight, either at birth or in early postnatal life.
尽管双胎妊娠与胎儿及出生后生长受限密切相关，但关于双胎出生后第一个月身体成分的具体数据却很匮乏。
本研究旨在比较通过空气置换体积描记法评估的双胎与孕龄及生长情况相似的单胎在出生后第一个月的身体成分。我们检验了生长质量相似这一假设。
对18对双胎和36名单胎新生儿从出生至出生后第30天进行纵向人体测量和空气置换体积描记法测量。每对双胎与一名孕龄和出生体重Z评分相似的单胎婴儿匹配。
在人体测量方面，唯一的差异是双胎在出生后第15天的体重低于单胎。在身体成分方面，我们在任何时间点均未发现两组之间存在差异。双胎和单胎的脂肪量从出生第1天到第30天均显著增加。
在身体成分方面，双胎在出生时及出生后早期与孕龄和体重相似的单胎并无差异。
