Children from wealthy families may more likely to have peanut allergies than those less well-off, a new study finds.

In the study, children ages 1 to 9 from high-income families had higher rates of peanut allergies compared with children these ages from lower income families.

The results add support to the hygiene hypothesis, said study researcher Dr. Sandy Yip, of the U.S. Air Force. The hygiene hypothesis is the idea that living in a cleaner environment may make people's immune systems more sensitive, and increase the prevalence of allergies.

The findings are also inline with those of a study published earlier this year, which found children living in cities were more likely to have food allergies compared with those living in rural areas, which tend to be less expensive than cities.

The study was presented this week at the American College of Allergy, Asthma and Immunology meeting in Anaheim, Calif.

Pass it on: Peanut allergies are more common in children from higher income families.
