Adequate and balanced nutrition during pregnancy is essential for both the mother's and fetus's health. The increased dietary intake of ultra-processed foods (UPFs) and their significant share in the diet negatively affects diet quality and gestational weight gain during pregnancy. The aim of this systematic review was to examine the association of UPFs consumption with diet quality and gestational weight change among healthy pregnant women, using data from observational studies (PROSPERO Identifier: CRD42023468269) from the last 10 years.
A search was performed in Pubmed, Wiley, Scopus, and Web of Science, and studies published in english language were selected. Study selection and data extraction were made by determining the exclusion and eligible inclusion criterias according to the PECOS framework. Of the 12 studies included, 5 were longitudinal cohort studies and 7 were cross-sectional studies. On average, half of the energy in the participants' daily diets came from UPFs in 3 studies, but the energy share of UPFs was about 20-30% in the remainder studies. UPFs-enriched maternal diet was associated with less dietary intake of legumes, vegetables, fruits and protein sources (seafood and plant protein, total protein) and greater consumption of refined grains compared to those who consume less UPFs. In parallel, UPFs consumption was negatively associated with Healthy Eating Index. UPF intake during pregnancy has a negative impact on diet quality and gestational weight gain. Increasing awareness of UPFs during this period may reduce potential complications during pregnancy and fetal growth.
怀孕期间充足和均衡的营养对母亲和胎儿的健康都至关重要。超加工食品（UPFs）的饮食摄入量增加及其在饮食中所占的重要比例，会对饮食质量和妊娠期间的体重增加产生负面影响。本系统综述的目的是使用过去 10 年来自观察性研究的数据（PROSPERO 标识符：CRD42023468269），研究健康孕妇中 UPFs 消费与饮食质量和妊娠体重变化之间的关系。
在 Pubmed、Wiley、Scopus 和 Web of Science 中进行了搜索，并选择了以英语发表的研究。根据 PECOS 框架确定排除和合格纳入标准进行了研究选择和数据提取。在纳入的 12 项研究中，有 5 项是纵向队列研究，7 项是横断面研究。平均而言，在 3 项研究中，参与者日常饮食中的一半能量来自 UPFs，但在其余研究中，UPFs 的能量份额约为 20-30%。富含 UPFs 的孕妇饮食与豆类、蔬菜、水果和蛋白质来源（海鲜和植物蛋白、总蛋白）的饮食摄入量较少以及精制谷物的摄入量较大有关，而与 UPFs 摄入量较低的孕妇相比。同时，UPFs 的摄入与健康饮食指数呈负相关。怀孕期间 UPFs 的摄入对饮食质量和妊娠体重增加有负面影响。在此期间提高对 UPFs 的认识可能会减少妊娠期间和胎儿生长的潜在并发症。
