Abstract： 目的 分析极低出生体重儿(very low birth weight infant,VLBWI)在纠正胎龄40周时的生长赶超情况及影响因素.方法 以50例VLBWI作为研究对象.以40周胎龄健康足月儿和15个城市不同胎龄婴儿出生体重为正常值,比较50例VLBWI在出生、出院时及纠正胎龄40周时的小于胎龄Jh(small for gestational age,SGA)发生率;分析喂养方式、并发症、辅助治疗等对VLBWI生长赶超的影响. 结果 50例VLBWI在纠正胎龄40周时的体重为(3290±640)g,与同胎龄足月儿比较差异无统计学意SL(P＞0.05).50例VLBWI出院时SGA所占比例为64.0%(32/50),明显高于出生时的24.0H(12/50)和纠正胎龄40周时的32.0%(15/50),P均＜0.05.出生时SGA(OR=0.035,95% CI 0.003～0.487)、低T3综合征(OR=0.101,95%CI 0.013～0.774)及长期使用静脉营养(OR=0.307,95%C1 0.097～0.972);是导致VLBWI生长赶超失败的危险因素,而早期开展肠道喂养(0R=8.241,95%CI 1.373～49.470)则有利于VLBWI的生长赶超.并发低T3综合征的VLBWI住院4周期间及出院后平均体重增长速度均低于未并发低T3综合征的VLBWI(P均＜0.05).结论 合理的营养方案、降低并发症的发生率是VLBWI实现早期生长赶超的关键.
