In the United States, about 25% of women choose not to initiate breastfeeding, yet little is known about how opinions of individuals in a woman's support network influence her decision to breastfeed. In the 2005-2007 Infant Feeding Practices Study II, women completed questionnaires from the last trimester of pregnancy until 12 months postpartum. Mothers indicated prenatally their family members' and health care providers' opinion on how newborns should be fed: breastfed only, formula fed only, breast and formula fed, or no opinion/don't know. Breastfeeding initiation was determined by asking mothers around 4 weeks postpartum (n=2,041) whether they ever breastfed. Logistic regression was used to examine the association between mothers' perception of family members' and health care providers' opinion on how to feed the infant and the initiation of breastfeeding, adjusting for sociodemographic characteristics. Nearly 14% of mothers surveyed did not initiate breastfeeding. Mothers who believed their family members or health care providers preferred breastfeeding only were least likely not to initiate breastfeeding. Never breastfeeding was significantly associated with the following perceptions: the infant's father (odds ratio [OR]=110.4; 95% CI 52.0 to 234.4) or maternal grandmother (OR=15.9; 95% CI 7.0 to 36.0) preferred only formula feeding; the infant's father (OR=3.2; 95% CI 1.7 to 5.9) or doctor (OR=2.7; 95% CI 1.2 to 6.2) preferred both breast and formula feeding; and the infant's father (OR=7.6; 95% CI 4.5 to 12.7), maternal grandmother (OR=5.4; 95% CI 2.6 to 11.0), or doctor (OR=1.9; 95% CI 1.0 to 3.7) had no opinion/didn't know their feeding preference. The prenatal opinions of family members and health care providers play an important role in a woman's breastfeeding decisions after the infant's birth.
在美国，约有 25%的女性选择不进行母乳喂养，而对于女性支持网络中个体的意见如何影响其母乳喂养决定，人们知之甚少。在 2005-2007 年婴儿喂养实践研究 II 中，女性从妊娠最后三个月到产后 12 个月完成问卷调查。母亲在产前表明了其家庭成员和医疗保健提供者对新生儿喂养方式的意见：仅母乳喂养、仅配方奶喂养、母乳喂养和配方奶喂养，或无意见/不知道。通过在产后约 4 周（n=2041）询问母亲是否曾经母乳喂养来确定母乳喂养的开始。使用逻辑回归来检查母亲对家庭成员和医疗保健提供者关于如何喂养婴儿的意见的看法与开始母乳喂养之间的关联，同时调整了社会人口统计学特征。接受调查的母亲中，近 14%没有开始母乳喂养。那些认为家庭成员或医疗保健提供者更喜欢母乳喂养的母亲最不可能不开始母乳喂养。从未母乳喂养与以下看法显著相关：婴儿的父亲（比值比[OR]=110.4；95%置信区间 52.0 至 234.4）或外祖母（OR=15.9；95%置信区间 7.0 至 36.0）更喜欢仅配方奶喂养；婴儿的父亲（OR=3.2；95%置信区间 1.7 至 5.9）或医生（OR=2.7；95%置信区间 1.2 至 6.2）更喜欢母乳喂养和配方奶喂养；婴儿的父亲（OR=7.6；95%置信区间 4.5 至 12.7）、外祖母（OR=5.4；95%置信区间 2.6 至 11.0）或医生（OR=1.9；95%置信区间 1.0 至 3.7）无意见/不知道他们的喂养偏好。家庭成员和医疗保健提供者的产前意见在女性分娩后母乳喂养决定中起着重要作用。
