Because of numerous health benefits for both mothers and babies, breastfeeding is the recommended method of infant feeding. We sought to determine the association between birth order and breastfeeding practices in families with multiple children.
The 2002 National Survey of Family Growth was used to analyze the demographic characteristics of a national probability sample of 2,115 U.S. mothers aged 15 to 44 with two, three, four, and five or more children younger than age 19. In-person, computer-assisted interviews were conducted by trained female interviewers. The main variable of interest was birth order; the main outcome measure was breastfeeding initiation for each mother-child pair. We used multiple logistic regression models to determine the demographic predictors of breastfeeding the second child in families with two children.
Mothers with two, three, four, and five or more children breastfed all of their children 52.6%, 48.4%, 44.7%, and 57.1% of the time, respectively (p = 0.46). In families with multiple children, more than 70% of women made the same feeding choice for each of their children, whether it was breastfeeding or bottlefeeding. After controlling for demographic factors, Hispanic women and women with more than a high school education were significantly more likely to breastfeed their second child if they had breastfed the first child.
U.S. mothers are likely to choose the same feeding method for each of their children, independent of the number of children they have. Breastfeeding promotion must take into consideration previous infant feeding experiences, if any.
由于母乳喂养对母亲和婴儿都有诸多健康益处，因此它是推荐的婴儿喂养方式。我们试图确定多子女家庭中出生顺序与母乳喂养行为之间的关联。
利用2002年全国家庭成长调查分析了2115名年龄在15至44岁之间、育有两名、三名、四名以及五名或更多19岁以下子女的美国母亲的全国概率样本的人口统计学特征。由经过培训的女性访谈员进行面对面的计算机辅助访谈。主要关注变量是出生顺序；主要结局指标是每对母婴的母乳喂养开始情况。我们使用多元逻辑回归模型来确定有两个孩子的家庭中母乳喂养第二个孩子的人口统计学预测因素。
育有两名、三名、四名以及五名或更多子女的母亲分别有52.6%、48.4%、44.7%和57.1%的时间对其所有子女进行母乳喂养（p = 0.46）。在多子女家庭中，超过70%的女性对其每个孩子都做出相同的喂养选择，无论是母乳喂养还是奶瓶喂养。在控制了人口统计学因素后，如果西班牙裔女性和受过高中以上教育的女性母乳喂养了第一个孩子，那么她们母乳喂养第二个孩子的可能性显著更高。
美国母亲可能会为其每个孩子选择相同的喂养方式，而与她们所育子女的数量无关。母乳喂养推广必须考虑到以往的婴儿喂养经历（如果有的话）。
