Children from middle class families more likely to suffer peanut allergy

Suggests that  oversanitization might suppress the natural development of the immune system

Children who have a peanut allergy tend to come from wealthier families, researchers have suggested.

Scientists say that this backs up the hygiene hypothesis that cleaner homes tend to increase the risk of childhood allergies.

They found that high income and hygiene habits could be increasing susceptibility as they discovered a link between peanut allergy in children and their families socio-economic status.

With the number of peanut allergies among children increasing the team from the American College of Allergy, Asthma, and Immunology (ACAAI) believe that one reason might be due to the wealth of their families.

The theory suggests that a lack of early childhood exposure to germs increases the chance for allergic diseases, that over sanitisation might suppress the natural development of the immune system.

Peanut allergy can be life-threatening with sufferers going into anaphylactic shock, but more commonly it causes itching in the mouth, a rash and swelling of the face, lips, eyes and tongue.

Study author Dr Sandy Yip said: “Overall household income is only associated with peanut sensitization in children aged one to nine years.

“This may indicate that development of peanut sensitization at a young age is related to affluence, but those developed later in life are not.”

Her team looked at 8,306 patients, 776 of which had an elevated antibody level to peanuts.

Peanut allergy was generally higher in men and racial minorities across all age groups. The researchers also found that peanut specific antibody levels peaked between the ages of 10 and 19, but tapered off after middle age.

ACAAI president Doctor Stanley Fineman said: “While many children can develop a tolerance to food allergens as they age, only 20 per cent will outgrow a peanut allergy.

The availability of the free application on May 5 at the iTunes store coincides with the World Health Organization’s (WHO) “5 Moments for Hand Hygiene” campaign. The campaign, which is part of the WHO’s “Save Lives: Clean Your Hands” annual initiative, spells out the standard opportunities for health care workers to practice hand hygiene.

“iScrub simplifies the time-consuming and error-prone process of recording observations, analyzing the data, and feeding results back to health care professionals and managers,” said Philip Polgreen, M.D., one of the application’s developers and an assistant professor of internal medicine at the UI Roy J. and Lucille A. Carver College of Medicine.
