(HealthDay) -- The prevalence of childhood food allergy is associated with urban/rural status, even after adjusting for confounding variables, according to a study published online May 17 in Clinical Pediatrics.

To estimate the prevalence and severity of by , Ruchi S. Gupta, M.D., M.P.H., of the Northwestern University Feinberg School of Medicine in Chicago, and associates analyzed data from a randomized survey of 38,465 children younger than age 18, administered from June 2009 to February 2010.

The researchers found that increasing population density corresponded with higher food allergy prevalence rates, with 9.8 percent of children affected in urban centers and 6.2 percent affected in rural areas. Graded odds were noted for food allergy, with the highest likelihood for urban versus rural areas (odds ratio, 1.7) followed by metropolitan versus rural areas (odds ratio, 1.4). The association remained significant even after adjusting for confounding variables, including race/ethnicity, gender, age, , and latitude.

"An association between urban/rural status and prevalence of food allergy was observed," the authors write. "Understanding the influence of geography on the pathogenesis of food allergy holds promise for the treatment and management of disease and warrants further investigation."
