The LOVE MOM cohort (Longitudinal Outcomes of VLBW Infants Exposed to Mothers' Own Milk; NIH: R010009; Meier PI) enrolled 430 infants with very low birth weight (VLBW) between 2008 and 2012 to study the impact of the dose and exposure period of MOM during hospitalization in the neonatal intensive care unit (NICU) on potentially preventable complications of prematurity and their associated costs. In this prospective study, MOM and formula feedings were calculated daily (mL), medical diagnoses for NICU morbidities (necrotizing enterocolitis [NEC], late-onset sepsis [sepsis], and bronchopulmonary dysplasia [BPD]) were confirmed independently by 2 neonatologists, and propensity scoring was used to analyze covariates. Neurodevelopmental outcome was measured for a subset of 251 LOVE MOM infants at 20 months of age, corrected for prematurity (CA). Data revealed a dose-response relationship between higher amounts of MOM received during critical NICU exposure periods and a reduction in the risk of NEC, sepsis, BPD, and their costs, as well as higher cognitive index scores at 20 months CA. MOM appears to function via different mechanisms during NICU exposure periods to reduce the risk of potentially preventable complications and their costs in VLBW infants. Institutions should prioritize the economic investments needed to acquire, store, and feed high-dose MOM in this population.
“爱母”队列研究(极低出生体重儿母乳喂养的纵向结局;美国国立卫生研究院:R010009;迈尔·PI)在2008年至2012年期间招募了430名极低出生体重(VLBW)婴儿,以研究新生儿重症监护病房(NICU)住院期间母亲自己的母乳(MOM)的剂量和暴露时间对早产潜在可预防并发症及其相关费用的影响。在这项前瞻性研究中,每天计算MOM和配方奶的喂养量(毫升),两名新生儿科医生独立确认NICU疾病(坏死性小肠结肠炎[NEC]、晚发性败血症[败血症]和支气管肺发育不良[BPD])的医学诊断,并使用倾向评分分析协变量。对251名“爱母”队列研究婴儿中的一部分在20个月龄时进行神经发育结局测量,并根据早产情况进行校正(CA)。数据显示,在NICU关键暴露期接受较多MOM与NEC、败血症、BPD风险及其费用降低之间存在剂量反应关系,以及在20个月CA时认知指数得分较高。在NICU暴露期,MOM似乎通过不同机制发挥作用,以降低VLBW婴儿潜在可预防并发症的风险及其费用。各机构应优先进行必要的经济投资,以获取、储存和喂养该人群的高剂量MOM。
