目标。我们研究了母乳喂养的开始和持续时间与语言和运动技能发展的关系，研究对象是美国10至71个月的儿童，具有全国代表性。利用2003年全国儿童健康调查的22399名儿童的横断面数据，我们研究了母乳喂养与儿童语言和运动技能发展之间的关系。结果是基于每位母亲对她对孩子的表达性语言、接受性语言、精细运动技能和大运动技能发展的关注程度（很多、一点、一点）的回答。母乳喂养数据基于母亲的回忆。采用方差估计方法和多元多项式回归模型，在调整混杂因素后，估计母乳喂养开始和持续时间对儿童发育的影响。样本平均年龄2.79岁；67%为非西班牙裔白人，16%为西班牙裔，9%为非西班牙裔黑人。大约17%的母亲表示担心孩子的表达性语言发展；大约10%的人有接受性语言问题；大约6%的人担心精细运动技能；5%的人报告了一般运动技能方面的问题。多变量分析显示，开始母乳喂养的母亲比从未母乳喂养孩子的母亲更不可能关注孩子的表达性和接受性语言发展以及精细和一般运动技能。母乳喂养3到5.9个月的孩子的母亲比从未母乳喂养的孩子的母亲更不可能关注孩子的表达性和接受性语言以及精细和一般运动技能。与所有的横断面数据一样，结果应谨慎解释。我们的研究结果表明，母乳喂养可以防止幼儿语言和运动技能发展的延迟。对于母乳喂养1 ~ 3个月的儿童，对语言和运动技能发展的担忧明显减少，随着母乳喂养持续1 ~ 9个月，这种担忧普遍减少。
Objectives. We examined the associations of breastfeeding initiation and duration with language and motor skill development in a nationally representative sample of US children aged 10 to 71 months.Methods. Using cross-sectional data on 22 399 children from the 2003 National Survey of Children's Health, we examined relationships between breastfeeding practices and children's language and motor skills development. Outcomes were based on each mother's response to questions regarding her level of concern (a lot, a little, not at all) about her child's development of expressive language, receptive language, fine motor skills, and gross motor skills. Breastfeeding data were based on mothers' recall. Methods of variance estimation were applied and multivariate polynomial regression modeling was done to estimate the effects of breastfeeding initiation and duration on children's development after adjustment for confounders.Results. Mean age of the sample was 2.79 years; 67% were non-Hispanic white, 16% were Hispanic, and 9% were non-Hispanic black. Approximately 17% of mothers reported concerns about their child's expressive language development; similar to 10% had receptive language concerns; similar to 6% had concerns about fine motor skills; and 5% reported general motor skills concerns. Multivariate analysis revealed that mothers who initiated breastfeeding were less likely than mothers of never-breastfed children to be concerned a lot about their child's expressive and receptive language development and fine and general motor skills. Mothers of children breastfed 3 to 5.9 months were less likely than mothers of never-breastfed children to be concerned a lot about their child's expressive and receptive language and fine and general motor skills.Conclusions. As with all cross-sectional data, results should be interpreted with caution. Our findings suggest breastfeeding may protect against delays in young children's language and motor skill development. Fewer concerns about language and motor skill development were evident for children breastfed >= 3 months, and concerns generally decreased as breastfeeding continued >= 9 months.
