Babies Who Eat Fish Lower Eczema Risk

FRIDAY, Sept. 26 (HealthDay News) -- Babies who start eating fish before the age of 9 months have a lower risk of developing eczema, new research shows.

The study, reported in a recent issue of theArchives of Disease in Childhoodalso found that one in five infants suffer from the skin condition in western Sweden.

The American Academy of Pediatrics issued a recommendation in 2000 for children at risk for eczema that parents hold off on various foods until they were older, including eliminating fish until they turned 3, said Dr. Sandra McMahan, an assistant professor of internal medicine with the Texas A&M Health Science Center College of Medicine and an allergist/immunologist at Scott & White.

In 2008, the academy reversed many of those recommendations, saying that children as young as 4 months to 6 months could have various foods, including fish, as there was no convincing evidence of harm.

Now it appears fish might actually make a positive difference.

"There has been a been a fear of early fish introduction, especially in infants with a family history of allergic disease," said study author Dr. Bernt Alm, a pediatrician with The Queen Silvia Children's Hospital, University of Gothenburg in Gothenburg, Sweden. "We have been afraid that this could lead to eczema and other allergic diseases. With this new knowledge, it is possible to relieve the parents from the burden of this fear," Alm said.

The proportion of allergic disease, including atopic eczema, has increased dramatically in developed countries in recent years. Although heredity is a strong factor in the development of such conditions, environmental and dietary factors also play a role.

These findings line up with previous research showing that mothers who fill up on apples and fish during pregnancy might protect their children from developing asthma and allergic diseases.

The authors of this study relied on medical records, as well as questionnaires filled out by parents when their children were 6 months of age and 1 year. All children were born in western Sweden in 2003.

By 12 months of age, almost 21 percent of infants had eczema or had experienced it previously. The average age of onset was 4 months.

The strongest risk factor was a family history, particularly children of mothers and siblings who had had eczema.

Infants who started eating fish before 9 months of age, however, were 25 percent less likely to be affected. Children who lived in a household with a bird were also less likely to develop eczema, possibly because birds are usually kept inside, exposing children continuously to endotoxin, toxins found inside pathogens.
