这项前瞻性研究的目的是调查母乳喂养与12个月大时的智力和运动发育之间的关系，控制儿童的社会经济，母亲和环境背景以及营养状况的综合措施。2001年5月至8月期间出生于伯南布哥州内陆贫困地区的205名婴儿组成的队列被纳入研究，其中191名婴儿在12个月大时接受贝利婴儿发育量表II测试，并在第1、10、30、60、90、120、150、180、270和360天测量母乳喂养状况。在调整潜在混杂因素后，与部分母乳喂养或无母乳喂养相比，1个月时完全母乳喂养（即完全母乳喂养或主要母乳喂养）与智力发育的小但显著的益处（+3.0分，P = 0.02）相关。长时间的全母乳喂养对智力发育没有额外的好处。1个月时的全母乳喂养与10个等级中的两个等级的行为改善相关：主动任务（P = 0.003）和注意力（P = 0.02）。没有发现母乳喂养和运动发育之间的联系。
The aim of this prospective study was to investigate the association between breast feeding and mental and motor development at age 12 months, controlling for comprehensive measures of the child's socio-economic, maternal and environmental background, and nutritional status. A cohort of 205 infants born during May-August 2001 in a poor area in the interior of the State of Pernambuco was enrolled, of whom 191 were tested at age 12 months with the Bayley Scales of Infant Development II, and in whom breast-feeding status was measured at days 1, 10, 30, 60, 90, 120, 150, 180, 270 and 360. After adjusting for potential confounders, full breast feeding (i.e. exclusive or predominant) at 1 month was associated with a small but significant benefit in mental development (+3.0 points, P = 0.02) compared with partial or no breast feeding. No additional advantage in mental development was found with longer durations of full breast feeding. Full breast feeding at 1 month was associated with improved behaviour for two of 10 ratings tested: initiative with tasks (P = 0.003) and attention (P = 0.02). No association between breast feeding and motor development was found.
