【medical-news】母乳喂养可降低发生风湿性关节炎

Women who breast feed for a longer period of time are less likely to get rheumatoid arthritis, according to a study published on May 13, 2008 in the Annals of the Rheumatic Diseases, a BMJ Specialist journal.

In the last thirty years, the fraction of women breastfeeding for more than six months has increased substantially. This study examined the effects of breast feeding, administration of oral contraceptives, and having children (but not breast feeding) on rheumatoid arthritis. The investigators studied 136 women with rheumatoid arthritis and 544 women without the disease.

The only group that experienced reduced rheumatoid arthritis had children and breastfed for extended periods of time. Those who breastfed longer were more likely to decrease arthritis risk. In comparison to the group that never participated in breastfeeding, women who had breastfed for one to 12 months had only three-quarters the chance of getting the disease. Women who had breastfed for 13 months or more had half the chance of getting rheumatoid arthritis as those who had never breastfed.

Notably, this relationship was not found with the use of oral contraceptives, which mimic the hormonal effects of pregnancy.

The authors concluded that there was some difficulty in drawing a direct connection between the higher rates of breast feeding and the correlating drop in the number of women affected by rheumatoid arthritis. However, they claim that the study shows another reason why women might consider to continue breast feeding.

从长远来看,采取母乳喂养的妇女患类风湿性关节炎的可能性更小,根据一项2008年5月13日发表在《风湿病年鉴》(一种BMJ专业杂志)上的研究。
In the last thirty years, the fraction of women breastfeeding for more than six months has increased substantially. This study examined the effects of breast feeding, administration of oral contraceptives, and having children (but not breast feeding) on rheumatoid arthritis. The investigators studied 136 women with rheumatoid arthritis and 544 women without the disease.
在过去的30年,伴超过6个月母乳喂养史的妇女比例有质的增加。这项研究观察了母乳喂养、服用口服避孕药及抚养孩子(非母乳喂养)对类风湿性关节炎患病率的影响。调查者研究了136名患类风湿性关节炎的妇女和544名无此疾病的妇女。
The only group that experienced reduced rheumatoid arthritis had children and breastfed for extended periods of time. Those who breastfed longer were more likely to decrease arthritis risk. In comparison to the group that never participated in breastfeeding, women who had breastfed for one to 12 months had only three-quarters the chance of getting the disease. Women who had breastfed for 13 months or more had half the chance of getting rheumatoid arthritis as those who had never breastfed.
只有一组患类风湿性关节炎比率减少了,她们有孩子并采取母乳喂养超过了一定时间。那些母乳喂养时间越长的,关节炎的风险更可能下降的越多。和从不母乳喂养的组比较,有1至12个月母乳喂养史的妇女只有四分之三的可能患此种疾病。有13个月或更长时间母乳喂养史的妇女有一半的可能患上类风湿性关节炎,和从不采用母乳喂养的妇女比较。
Notably, this relationship was not found with the use of oral contraceptives, which mimic the hormonal effects of pregnancy.
值得注意的是,这种相关性没有在使用口服避孕药的妇女中发现(这些药物模拟妊娠的激素效应)。
The authors concluded that there was some difficulty in drawing a direct connection between the higher rates of breast feeding and the correlating drop in the number of women affected by rheumatoid arthritis. However, they claim that the study shows another reason why women might consider to continue breast feeding.
作者总结到,画出一个图表直接说明两者的关系有些困难——母乳喂养率越高,妇女患上类风湿性关节炎的人数就相应的越少。然而,他们声称这项研究就为什么妇女应该考虑继续母乳喂养提供了另外一个理由。
Breast feeding, but not use of oral contraceptives, is associated with a reduced risk of rheumatoid arthritis
母乳喂养,且弃用口服避孕药,和减少类风湿性关节炎风险相关。
