Beat Eczema - The infant eczema
Children living near the line of the equator are less likely to have eczema and allergies food allergy live in some small areas that are not so sunny, offers an observation that the evidence that low levels of vitamin D levels increase ecological, the risk of developing allergy.

The team of Dr. Nicholas Osborne, University of Exeter, UK, has identified a latitudinal gradient with Beat Eczema and allergies to peanuts and eggs in a study of over 7,000 children associated.

"This research further confirms our conviction to continue to explore possible causal influence of environmental factors, UV radiation and vitamin D in this group of diseases," the team wrote in a letter published in the Journal of Allergy and Clinical Immunology.

The authors used data from the third stage of longitudinal Australian study on children, conducted with 3,000,312 children aged 4-5 years, and 4,000,331 children aged eight and nine, in 2008.

They estimated that 4,000,500 kilometers of Australia from north to south between 10 and 43 degrees south latitude, and their high rates of allergies and asthma, "making the country the place to analyze these associations. "

Eczema more concentrated latitudinal gradient in both age groups. Among children had eczema less than 9 percent of respondents residing in the north (10-29 ° S), compared to 15 percent of people in the Midwest (29-35 ° S) and 19 percent of people in the south (35-43 ° S).

In this group, according to a multivariate analysis and the northern region (closest to the equator) as reference, the team that the children 75 percent more likely to have eczema if they lived in the Midwest and were more than twice as likely, if residing in the south.

Participants from eight to nine years, was the rate of eczema by 8 percent in the area north of housing, 12 percent in central Europe and 13 percent in the South. The adjusted relative risk for the Midwest and South was 1.6 and 1.9.

The team identified latitudinal gradient similar to peanut allergy in both age groups and for egg allergy in the smallest group (these allergies are not studied in older children, as no case in the north).

The prevalence of allergy to cow's milk, wheat, or "other" foods do not vary with latitude. The same happens with allergies to soy and sesame, but because both were rare, the study would not have detected differences.

"We are not surprised by the lack of a link between food allergies and other latitudes, because other biological mechanisms, such as allergies and non-IgE mediated food intolerances, unlike IgE-mediated allergy possible, "wrote the team.

The authors also detected a latitudinal gradient in the prevalence of asthma, suggesting that "the development of asthma should perhaps different pathological mechanisms of allergies to peanuts and eggs."

"In order to study these phenomena with meteorological data such as temperature and sunlight, and the serological analysis of vitamin D, would be other clues to the nature of these associations offer," the researchers conclude. Beat Eczema
