Babies benefit from breast-feeding—they have a lower risk of infections, vomiting and diarrhea and less of a chance of later developing adult onset diabetes. And now a study finds that being breast-fed helps protect infants who are genetically predisposed to be at risk for asthma. The work was recently presented at the European Respiratory Society's International Congress in London.
Researchers collected data about 368 Swiss infants—such as the frequency and intensity of respiratory symptoms. They also tracked whether the infants were breast-fed. And they performed genomic analysis of the children.
The results: infants carrying genes that put them at increased risk for asthma had a 27 percent decrease in developing respiratory symptoms while being breast-fed. The same children showed a trend toward the risk going back up when they were not being breast-fed.
The study sheds light on the interactions between genes and the environment when it comes to asthma. The researchers note that they need to replicate the study in another group of infants to see if the findings hold. But if further work has a similar outcome, it could lead to better ways to let affected individuals breathe easier.

宝宝受益于母乳喂养，这些宝宝患感染病、呕吐、痢疾的风险较低，他们成人后得糖尿病的几率也较低 。现在一项研究发现，母乳喂养有助于保护那些先天易得哮喘病的婴儿 。该研究结果于近期在伦敦举行的欧洲呼吸协会会议上发布 。
研究人员收集了368名瑞士婴儿在呼吸道疾病频率和强度等方面的数据 。他们也对这些婴儿是否是母乳喂养进行了追踪调查 。他们对这些孩子进行了基因分析 。
研究结果：携带患有哮喘基因的婴儿，经过母乳喂养后，发展成为呼吸道疾病的几率降低了27% 。这些婴儿在不进行母乳喂养后，患哮喘的几率会回升 。
这项研究揭示了基因和环境在哮喘方面的相互作用 。研究人员指出，他们需要对另外一组婴儿进行同样的研究，以测试研究结果是否依旧成立 。如果后续研究得出类似的结果，那就可以找到更好的方法，让感染的婴儿呼吸更顺畅 。
