Abstract：
BACKGROUND: Dietary fat intake in pregnancy, lactation, and childhood determines child growth, neurodevelopment, and long-term health.
METHODS: We performed a scoping review of dietary guidelines on fat intake for pregnant and lactating women, infants, children, and adolescents. We systematically searched several databases and websites for relevant documents published in English from 2015 to 2019.
RESULTS: We included 14 documents. Of those, eight targeted pregnant and/or lactating women, mainly recommending daily intake of approx. 250 mg/d of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), while one advised supplementing 800 mg/d DHA and 100 mg/d EPA in women of low omega-3 fatty acid status. The number of guidelines for infants was low (n = 3). Recommended intakes of total fat were 30-40% and 20-35% of total energy intake (TEI) for infants and children, respectively. Intakes of saturated fatty acids (SFAs) <10% of TEI and avoidance of trans-fatty acids (TFAs) were recommended across childhood. The methodology applied to develop guidelines and to grade the strength of recommendations was heterogeneous.
CONCLUSIONS: Quantitative recommendations on fat intake during pregnancy focused mainly on PUFA intake, and those targeting infants were limited. Consistent recommendations were provided for total fat, SFA, and TFA intake in childhood; however, strength of recommendation was mostly not reported.

摘要：
背景：怀孕期间的饮食脂肪摄入量，哺乳期,童年决定孩子的成长，神经发育，和长期健康。
方法：我们对孕妇和哺乳期妇女脂肪摄入量的饮食指南进行了范围审查，婴儿,孩子们,和青少年。我们系统地检索了多个数据库和网站，以获取2015年至2019年以英文发布的相关文献。
结果：我们包含了14个文档。其中,八名目标孕妇和/或哺乳期妇女，主要推荐每日摄入量约。250毫克/天的二十碳五烯酸（EPA）和二十二碳六烯酸（DHA），而一个建议补充800mg/dDHA和100mg/dEPA在低omega-3脂肪酸状态的女性。婴儿指南的数量较少（n=3）。推荐的总脂肪摄入量为婴儿和儿童总能量摄入量（TEI）的30-40％和20-35％，分别。建议在整个儿童时期摄入饱和脂肪酸（SFAs）＆lt;10％的TEI和避免使用反式脂肪酸（TFA）。用于制定准则和对建议强度进行评分的方法是异质的。
结论：关于怀孕期间脂肪摄入的定量建议主要集中在PUFA的摄入，那些针对婴儿的是有限的。为总脂肪提供了一致的建议，SFA,和儿童时期的TFA摄入量；然而，建议的强度大多没有报告。
