Breastfed infants pass more stools and more liquid stools than formula fed infants and some have no bowel movements or infrequent stools for several days or weeks. We compared exclusively breastfed and exclusively formula fed infants for the first three months.
This study of 118 infants was carried out in the maternity ward of the Lille University Jeanne de Flandre Hospital, France, in 2015. The outcomes were the number and consistency of stools and the prevalence of infrequent stools.
At three months, 84 infants remained and we compared 40 who were exclusively breastfed and 13 who were exclusively formula fed. Daily stool frequency was significantly higher in the breastfed than formula fed infants during the first (4.9 ± 1.7 vs. 2.3 ± 1.6, p < 0.001) and second (3.2 ± 1.6 vs. 1.6 ± 1.5, p = 0.003) months. Stools were more liquid in the breastfed infants during the first three months. Infrequent stools occurred in 28% of breastfed and 8% of formula fed infants at least once. (p = 0.25).
Exclusively breastfed infants produced more stools than exclusively formula fed infants during the first two months and more liquid stools during the first three. Infrequent stools were 3.5 times more likely in the breastfed infants.
与配方奶喂养的婴儿相比，母乳喂养的婴儿排便更多且更稀，有些婴儿甚至会连续几天或几周不排便。我们比较了前三个月纯母乳喂养和纯配方奶喂养的婴儿。
这项研究共纳入了 118 名婴儿，于 2015 年在法国里尔大学让娜·德·弗拉芒医院的妇产科病房进行。结果为粪便的数量和稠度以及排便不规律的发生率。
3 个月时，84 名婴儿仍在接受研究，我们比较了 40 名纯母乳喂养和 13 名纯配方奶喂养的婴儿。母乳喂养婴儿的每日排便频率在第 1 个月（4.9±1.7 次 vs. 2.3±1.6 次，p<0.001）和第 2 个月（3.2±1.6 次 vs. 1.6±1.5 次，p=0.003）显著高于配方奶喂养婴儿。在前 3 个月，母乳喂养婴儿的粪便更稀。至少有一次排便不规律的婴儿中，母乳喂养婴儿占 28%，配方奶喂养婴儿占 8%（p=0.25）。
在头两个月，纯母乳喂养的婴儿比纯配方奶喂养的婴儿产生的粪便更多，且前 3 个月粪便更稀。母乳喂养婴儿排便不规律的可能性是配方奶喂养婴儿的 3.5 倍。
