Late preterm (LP) and early term (ET) infants can be considered the "great dissemblers": they resemble healthy full-term infants in appearance, but their immaturity places them at increased risk of poor short- and long-term outcomes. Nutritional requirements are greater than for full-term babies, but there are few good data on the nutritional requirements for LP and ET babies, leading to substantial variation in practice. Recent data indicate that rapid growth may be beneficial for neurocognitive function but not for body composition and later metabolic health. Breastfeeding the LP or ET infant can be challenging, and mothers of these infants may need additional support to breastfeed successfully. Future research should investigate nutritional requirements of LP and ET infants for optimal growth, addressing both short- and long-term outcomes and the potential trade-off between neurocognitive and metabolic benefits.
晚期早产儿(LP)和早期足月儿(ET)可以被认为是“伪装者”:他们在外观上与健康的足月儿相似,但他们的不成熟使他们面临更高的短期和长期不良结局风险。营养需求大于足月儿,但关于 LP 和 ET 婴儿的营养需求的数据很少,导致实践中存在很大差异。最近的数据表明,快速生长可能有益于神经认知功能,但对身体成分和以后的代谢健康无益。喂养 LP 或 ET 婴儿可能具有挑战性,这些婴儿的母亲可能需要额外的支持才能成功母乳喂养。未来的研究应该调查 LP 和 ET 婴儿的营养需求,以实现最佳生长,既要解决短期和长期结局问题,又要解决神经认知和代谢益处之间的潜在权衡问题。
