BACKGROUND/AIMS: Studies about defecation patterns have been mostly conducted on infants who were breastfed in a short term but were fed predominantly with formula. In this study, defecation patterns of 125 infants, most of them being breastfed during 12th month were evaluated.
Frequency, consistency and color of the stool were analyzed in relation to the feeding pattern at the 15th day and at the 1st, 2nd, 3rd, 4th, 5th, 6th and 12th months.
Frequency of defecation was highest in 15th day with a median of 6/day. It decreased with age (p=0.0001), being 4/day and 3/day in 1st and 2nd months respectively, and 2/day between 3rd-12th months. During first 5 months, the stool frequency was higher in infants who were exclusively breastfed compared to those being fed with breastfed and formula (p<0.05). The effect of the feeding pattern on stool frequency disappeared in the following months (p>0.05). Stool frequency decreased by half at the 2nd month when the rate of less than once/day attained its highest value (24.8%). In those who had a rate of less than once/day, stool frequency stayed low until the 6th month and exclusively breastfed rate was also found lower (p<0.05).
Besides the age, exclusive breastfeeding was also effective on stool frequency. It points out that infants who are fed with formula in addition to breastfeeding may defecate less than once per day hence should not be diagnosed as having constipation depending solely on defecation frequency and should not receive unneccesary treatments.
背景/目的：关于排便模式的研究大多针对短期母乳喂养但主要以配方奶喂养的婴儿。在本研究中，对125名婴儿的排便模式进行了评估，其中大多数在12个月时主要进行母乳喂养。
分析了第15天以及第1、2、3、4、5、6和12个月时粪便的频率、稠度和颜色，并与喂养模式相关联。
排便频率在第15天时最高，中位数为每天6次。随着年龄增长而下降（p = 0.0001），在第1个月和第2个月分别为每天4次和3次，在第3至12个月期间为每天2次。在最初的5个月里，纯母乳喂养的婴儿排便频率高于母乳喂养加配方奶喂养的婴儿（p < 0.05）。在接下来的几个月里，喂养模式对排便频率的影响消失（p > 0.05）。在第2个月时排便频率减半，此时每天排便少于1次的比例达到最高值（24.8%）。在那些每天排便少于1次的婴儿中，排便频率在第6个月之前一直较低，并且纯母乳喂养的比例也较低（p < 0.05）。
除年龄外，纯母乳喂养对排便频率也有影响。这表明除母乳喂养外还添加配方奶喂养的婴儿可能每天排便少于1次，因此不应仅根据排便频率诊断为便秘，也不应接受不必要的治疗。
