Women who breastfed for at least a year have 50 percent less chance of developing rheumatoid arthritis, announced the Swedish scientists.
Comparing data of 136 women with rheumatoid arthritis with data collected from 544 healthy respondents, researchers from the University of Malmoe found that women who breastfed less than a year have on average 25 percent less risk of getting rheumatoid arthritis. Results released by the journal Annals of rheumatic diseases suggest that motherhood in itself does not have any protective effect on rheumatoid arthritis. It is already known that women are exposed to twice increased risk for this disease than men.

Scientists have not discovered a mechanism that would explain the results, and are further confused by the fact that breastfeeding increases the secretion of prolactine, hormone that stimulate the immune system, and that could even increase the chances for development of rheumatoid arthritis. In the same study was found that use of birth control pill does not reduce the risk of rheumatoid arthritis.
