To evaluate the suitability of the new nutritional composition of renewed commercial Formula A (protein reduced to 2.2 g/100 kcal, arachidonic acid increased to 13.2 mg/100 kcal, and docosahexaenoic acid maintained at 20 mg/100 kcal), we examined whether the growth of Formula A-fed infants was equivalent to that of breastfed infants. In this observational study, 1,053 infants were followed-up to 12 months. Growth, stool consistency, and the health condition of 99 infants fed with Formula A and 295 breastfed infants were compared. Body weight, body mass index, and head circumference of Formula A-fed infants were similar to those of breastfed infants. Additionally, there were no differences in the stool consistency and the health condition (infection and allergy prevalence) between the two groups. Formula A-fed infants grew as well as breastfed infants, suggesting the appropriate nutritional composition of Formula A. The findings may contribute to further improvements in infant formulas.

用蛋白质含量为2.2 g / 100 kcal的商业婴儿配方食品喂养的足月婴儿的生长：一项观察性随访研究。

为了评估更新的商业配方A的新营养成分的适用性（蛋白质降至2.2 g / 100 kcal，花生四烯酸增加至13.2 mg / 100 kcal，二十二碳六烯酸维持在20 mg / 100 kcal），我们检查了由配方A喂养的婴儿的生长与母乳喂养的婴儿的生长相同。在这项观察性研究中，对1,053例婴儿进行了随访，随访时间为12个月。比较了以配方奶A喂养的99例婴儿和295例母乳喂养的婴儿的生长，粪便稠度和健康状况。由配方A喂养的婴儿的体重，体重指数和头围与母乳喂养的婴儿相似。此外，两组之间的粪便稠度和健康状况（感染和过敏患病率）没有差异。
