目的 研究不同喂养方式对小于胎龄儿体重、身长、头围的影响。方法 将215名小于胎龄儿按照喂养方式分为5组:早产儿出院后配方奶喂养组、母乳喂养组、足月儿配方奶喂养组、母乳+早产儿出院后配方奶喂养组、母乳+足月儿配方奶喂养组, 比较各组在出生、生后1、3、6、12、18月及24月体重、身长、头围等生长发育指标。结果 不同喂养方式对小于胎龄儿体重、身长、头围发育的影响有统计学意义(P<0.05), 早产儿出院后配方奶喂养组及其与母乳混合喂养组儿童发育指标优于纯母乳喂养及足月儿配方奶喂养组, 其差异有统计学意义(P<0.05)。结论 小于胎龄儿出院后应用早产儿出院后配方奶喂养或与母乳混合喂养能够促进体重、身长、头围发展, 实现小于胎龄儿的追赶生长, 避免发生宫外生长发育迟缓的发生。

Objective To study the effect on small for gestational age child's weight, length, head circumference with different feeding way. Methods The 215 small for gestational age children were divided into five groups:preterm children after discharge formula-fed group, breast-fed group, full-term child formula-fed group, breast+preterm children after discharge formula-fed group, breast+full-term child formula-fed group.Weight, length and head circumference of each group were recorded at birth, 1 month, 3 months, 6 months, 12 months, 18 months and 24 months. Results The effects on small for gestational age child weight, length, head circumference with different feeding were statistically significant (P<0.05).Preterm children after discharge formula-fed group and mixed feeding with breast milk child development indicators were better than breast feeding and full-term children formula-fed group, the difference was statistically significant (P<0.05). Conclusion Using preterm children after discharge formula or breast-feeding or mixed feeding can contribute to growth of weight, length, head circumference, achieve catch-up growth and reduce or avoid extrauterine growth retardation.
