We assessed the anthropometric characteristics of symmetric (SGA-S) and asymmetric (SGA-A) term newborns and describe their subcutaneous fat differences. We assessed perinatal data, maternal characteristics and anthropometric variables (including skinfold thicknesses) in 139 small for gestational age (SGA) term infants, classified as symmetric and asymmetric according to their ponderal index (using the 10(th) percentile as the cut-off criterion). Despite an overall small body size and lower amounts of subcutaneous fat than the reference population, SGA-S term newborns showed a proportionate body fat distribution and SGA-A were thinner and had a lower percentage of central subcutaneous fat than SGA-S. These findings, resulting from intrauterine growth restriction, could be associated with different early and later postnatal outcomes among SGA groups.
我们评估了对称（SGA-S）和不对称（SGA-A）足月新生儿的人体测量特征，并描述了他们的皮下脂肪差异。我们评估了 139 名小于胎龄儿（SGA）足月婴儿的围产期数据、产妇特征和人体测量学变量（包括皮褶厚度），这些婴儿根据其体重指数（使用第 10 百分位数作为截断标准）被分类为对称和不对称。尽管整体身体较小，皮下脂肪量低于参考人群，但 SGA-S 足月新生儿的体脂分布比例适当，而 SGA-A 则更瘦，中央皮下脂肪百分比低于 SGA-S。这些由宫内生长受限引起的发现，可能与 SGA 组之间不同的早期和后期出生后结局有关。
