目的研究早产儿宫外生长迟缓的相关因素。方法选择我院2009年1月至2010年1月间存活出院的早产儿(出生体重儿<1500g),定期随访至12个月,给予生长发育监测,并对宫外生长迟缓相关因素进行分析。结果 123例早产儿以体重计生长迟缓(低于生长曲线第10百分位)的发生率:出生时为58.5%,出院时为80.5%,校正胎龄足月(37～42周)时为56.1%,3个月时39.2%,6～12个月时22.0%,宫外生长迟缓的危险因素包括出生低胎龄、宫内生长迟缓、生后反复感染、母亲合并妊娠高血压综合征、出院后营养强化。结论预防产前、生后危险因素,建立早期积极规范的营养支持,以促进早产儿生长发育。
Objective To study the related factors of ectopic growth retardation in preterm infants. Methods Preterm infants (birth weight <1500 g) who were discharged during hospitalization from January 2009 to January 2010 were selected. The patients were followed up for 12 months regularly to monitor the growth and development, and the related factors of ectopic growth retardation were analyzed. Results The incidence of delayed growth (lower than the 10th percentile of the growth curve) of 123 preterm infants was 58.5% at birth, 80.5% at discharge and at full-term gestational age (37-42 weeks) 56.1%, 39.2% at 3 months and 22.0% at 6 ~ 12 months. The risk factors for extrauterine growth retardation included low gestational age at birth, intrauterine growth retardation, repeated postnatal infection, maternal pregnancy-induced hypertension syndrome, Nutritional enhancement after discharge. Conclusion Prevention of prenatal and postnatal risk factors, the establishment of early active normative nutritional support to promote the growth and development of premature children.
