【BBC媒体英语】宠物狗“可能有助儿童避免患哮喘” Pet d 本站原创 更新时间: 2019-11-29         

瑞典的一项大型研究项目发现,家中有宠物狗的低龄孩子日后不大可能患哮喘。BBC记者 Michelle Roberts 有以下报道:

Many people are allergic to dogs, or at least the dead skin cells and saliva that they shed as they groom themselves.

许多人对狗过敏,或者至少对它们自己打扮时脱落的死皮细胞和唾液过敏。

But a new piece of research from Sweden suggests early exposure to these pets could cut a child's future risk of allergy. Living with a dog in the home in the first year of life was linked to a 13% lower risk of asthma in later childhood among the 650,000 children the authors tracked.

但是来自瑞典的一项新研究表明,尽早接触这些宠物可以减少孩子将来过敏的风险。 作者追踪的65万名儿童中,在第一年与狗同居与低发哮喘风险相比降低了13%。

The researchers say this fits with the hygiene hypothesis which favours exposure to dust and dirt to improve our tolerance of common allergens. But for a child who is already allergic to dogs, buying a puppy would not be a good idea.

研究人员说,这符合健康假说,该假说倾向于暴露于灰尘和污垢,以提高我们对常见过敏原的耐受性。 但是对于一个已经对狗过敏的孩子来说,买一只小狗不是一个好主意。
