A woman breastfeeds her baby in Bordeaux, southwest France April 27, 2006. Children breast-fed as infants are less likely to wet the bed later on, researchers reported on Wednesday, probably because they have a developmental edge. There is strong evidence that in many cases bed-wetting can "result from delayed neurodevelopment," said the report from the Robert Wood Johnson Medical School in New Brunswick, New Jersey. "There is biological plausibility in inferring that breast-feeding protects against bed-wetting and our results show a strong statistical association" although not enough to prove a direct cause-effect. Breast-feeding is beneficial because of the role that certain fatty acids passed onto the infant play in brain development, said the study published in the July issue of Pediatrics, the journal of the American Academy of Pediatrics. The study was based on 55 children who were bed-wetters at ages 5 to 13 and 117 in the same age range who were not. Of the bed-wetters, 45 percent had been breast-fed, compared to 81 percent of those who were continent at night. (Agencies)

本周三，研究人員公布，嬰兒期喝母乳的兒童以后不容易尿床。這可能是因為用母乳喂養(yǎng)的孩子發(fā)育的比較好。 此研究報告由新澤西州新不倫瑞克羅伯特·伍德·約翰遜醫(yī)科學校發(fā)表。報告稱，事實有力證明，在很多情況下，尿床都是"緣于神經(jīng)發(fā)育遲緩"。 “說母乳喂養(yǎng)能夠防止尿床，這在生物學上是能講得通的，而且我們的研究結(jié)果也為此提供了有力的數(shù)據(jù)支持。”但這些數(shù)據(jù)還不足以證明二者之間存在直接的因果關(guān)系。 研究報告中說，母乳喂養(yǎng)是有好處的，因為嬰兒在母乳中所吸收的某些脂肪酸能促進大腦發(fā)育。此研究報告發(fā)表在美國兒科研究會期刊《兒科》的7月號上。 此項研究的研究對象為55名年齡在5歲至13歲之間的尿床兒童以及117名相同年齡段的非尿床兒童。在尿床兒童中，有45％是母乳喂養(yǎng)的，而在那些不尿床的兒童中，該比重是81％。 (英語點津姍姍編輯)
