I always felt that exposure to animals was good for children, but I meant

Early exposure to farm animals lowers IBD risk 

NEW YORK (Reuters Health) - Infants who are regularly exposed to farm animals 
appear to be less likely than others to develop inflammatory bowel disease in 
childhood, according to the findings of a German study published in the 
journal Pediatrics. 

"Approximately 12,000 children and adolescents in Germany suffer from 
inflammatory bowel disease (IBD)," write Dr. Katja Radon and colleagues at 
Ludwig-Maximilians-University, Munich. The recent increase in Crohn's 
disease, a type of inflammatory bowel disease, especially in industrialized 
countries, and its pronounced geographical variation, suggest that 
environmental factors contribute this condition.

The researchers examined the association between contact with farm animals in 
infancy and the development of Crohn's disease or ulcerative colitis in 
childhood. Data were analyzed for 748 IBD cases (444 with Crohn's disease and 
304 with ulcerative colitis) and 1,481 healthy "control" children.

The children with IBD were more likely than the control children to live in 
urban areas. Regular contact with farm animals during the first year of life 
was inversely associated with IBD, the investigators report.

Specifically, the children with Crohn's disease or ulcerative colitis were 
about 50 percent less likely to have regular contact with farm animals in 
infancy compared with the healthy children.

"The results of this study indicate that farm animal contact during infancy, 
one of the major factors protecting individuals against childhood allergies, 
might also decrease the risk of juvenile IBD," Radon's team concludes. The 
findings also support the hypothesis that allergic diseases and IBD might 
have similar paths of development.
