The aim of this study was to examine the relationship between duration of breastfeeding and educational outcomes. We hypothesized that longer periods of breastfeeding would predict better educational outcomes in middle childhood.
The Western Australian Pregnancy Cohort (Raine) Study used a cohort of 2900 women who were enrolled at 18 weeks' gestation; with 2868 live-born children were followed prospectively. At ∼10 years of age, data from 1038 children were linked to standardized mathematics, reading, writing, and spelling scores. Associations between breastfeeding duration and educational outcomes were estimated by using linear models with adjustment for gender, family income, maternal factors, and early stimulation at home through reading.
Ten-year-old children who were predominantly breastfed for 6 months or longer in infancy had higher academic scores than children who were breastfed for less than 6 months. The effect of breastfeeding on educational outcomes differed according to gender; boys were particularly responsive (in mathematics, spelling, reading, and writing) to a longer duration of breastfeeding.
Predominant breastfeeding for 6 months or longer was positively associated with academic achievement in children at 10 years of age. However, the effectiveness of breastfeeding differed according to gender; the benefits were only evident for boys.
本研究旨在探讨母乳喂养时长与教育成果之间的关系。我们假设，母乳喂养时间较长与儿童中期的更好教育成果相关。
西澳大利亚妊娠队列（Raine）研究纳入了 2900 名 18 周妊娠的女性，其中 2868 名活产儿进行了前瞻性随访。在 10 岁左右，1038 名儿童的数据与标准化的数学、阅读、写作和拼写分数相关联。通过线性模型调整性别、家庭收入、产妇因素和家庭早期阅读刺激等因素后，评估母乳喂养时长与教育成果之间的关系。
与母乳喂养少于 6 个月的儿童相比，婴儿期主要母乳喂养 6 个月或更长时间的 10 岁儿童具有更高的学业成绩。母乳喂养对教育成果的影响因性别而异；男孩对较长的母乳喂养时间特别敏感（在数学、拼写、阅读和写作方面）。
主要母乳喂养 6 个月或更长时间与儿童 10 岁时的学业成绩呈正相关。然而，母乳喂养的效果因性别而异；仅对男孩有效。
