Abstract

Purpose: This study compared the iron statuses of small for gestational age (SGA) and appropriate for gestational age (AGA) infants at birth.

Methods: The clinical data of 904 newborn infants admitted to the neonatal intensive care unit were reviewed. Blood samples were drawn from the infants within 24 hours after birth. Serum ferritin level was used as a marker of total iron status.

Results: In this study, 115 SGA (GA, 36.5±2.9 weeks; birth weight [BW], 1,975±594.5 g) and 717 AGA (GA, 35.1±3.5 weeks; BW, 2,420.3±768.7 g) infants were included. The SGA infants had higher hematocrit levels (50.6%±5.8% vs. 47.7%±5.7%, P<0.05) than the AGA infants. No difference in serum ferritin level (ng/mL) was found between the groups (mean [95% confidence interval]: SGA vs. AGA infants, 139.0 [70.0-237.0] vs. 141.0 [82.5-228.5]). After adjusting for gestational age, the SGA infants had lower ferritin levels (147.1 ng/mL [116.3-178.0 ng/mL] vs. 189.4 ng/mL [178.0-200.8 ng/ mL], P<0.05). Total body iron stores were also lower in the SGA infants than in the AGA infants (185.6 [153.4-211.7] vs 202.2 [168.7-241.9], P<0.05).

Conclusion: The SGA infants had lower ferritin and total body iron stores than the AGA infants. The SGA infants affected by maternal hypertension who were born at late preterm had an additional risk of inadequate iron store. Iron deficiency should be monitored in these infants during follow-up.

铁含量低于胎龄，适合胎龄婴儿出生。

目的:本研究比较小胎龄(SGA)和适当胎龄(AGA)婴儿出生时的铁状况。方法:回顾性分析新生儿重症监护病房904例新生儿的临床资料。婴儿在出生后24小时内抽取血液样本。血清铁蛋白水平作为总铁状态的标志。结果:本研究中，115例SGA (GA, 36.5±2.9周;出生体重[BW]， 1975±594.5 g)和717 AGA (GA, 35.1±3.5周);新生儿体重，2420.3±768.7 g)。SGA患儿红细胞压积(50.6%±5.8%)高于AGA患儿(47.7%±5.7%)。结论:SGA患儿的铁蛋白含量和体内总铁储量低于AGA患儿。受母亲高血压影响的晚期早产SGA婴儿有铁储存不足的额外风险。在随访期间应监测这些婴儿的缺铁情况。
