This systematic review aimed to examine differences in growth outcomes between breastfed infants and infants fed with formula with different protein/energy ratios during the first six months of life. We conducted a systematic review in the PubMed, Web of Science, and Springer databases. Twenty clinical trials qualified for inclusion. We extracted data about the growth outcomes of infants who were exclusive breastfed or exclusively infant formula fed in the first six months and used a meta-analysis to pool the finding data. We categorized study formulas into four groups according to their protein content: <1.8, 1.8−2.0, 2.1−2.2, and >2.2 g/100 kcal. In the first month of life, growth was not different between formula- and breastfed infants. During 2−3 months of life, growth was faster in infants who consumed formulas with protein contents higher than 2.0 g/100 kcal. After 3 months, formula-fed infants grew faster than breastfed infants. Our meta-analysis indicated that the growth outcomes of infants fed with infant formula with a relatively low protein/energy ratios, compared with that a relatively high protein/energy ratio, were close to those of breastfed infants.
本系统评价旨在研究在生命的头六个月中，母乳喂养婴儿和不同蛋白质/能量比配方奶喂养婴儿的生长结果差异。我们在 PubMed、Web of Science 和 Springer 数据库中进行了系统评价。20 项临床试验符合纳入标准。我们提取了前六个月中纯母乳喂养或纯配方奶喂养婴儿的生长结果数据，并使用荟萃分析来汇总发现数据。我们根据蛋白质含量将研究配方分为四组：<1.8、1.8-2.0、2.1-2.2 和>2.2 g/100 kcal。在生命的第一个月，配方奶喂养和母乳喂养婴儿的生长没有差异。在 2-3 个月时，摄入蛋白质含量高于 2.0 g/100 kcal 的配方奶的婴儿生长更快。3 个月后，配方奶喂养的婴儿比母乳喂养的婴儿生长更快。我们的荟萃分析表明，与高蛋白质/能量比相比，低蛋白质/能量比配方奶喂养婴儿的生长结果与母乳喂养婴儿接近。
