Children from low-income backgrounds, she noted, spend less on specialty outpatient care.
The difference in food allergy rates is likely linked, in part, to familial and cultural differences in childrearing, she said. African-American and Hispanic parents tend to introduce solid foods earlier, and breastfeed children at lower rates than those of white families.
Dr. Mahdavinia noted that while more affluent families are able to sidestep allergies by making a simple stop at a high-end grocer to get an allergen-free version of a food, poorer families are less able to buy these more expensive alternatives.
“The higher rate of asthma anaphylaxis observed in these minority children is concerning, especially when it’s considered in the context of the reported higher rate of fatal anaphylaxis associated food allergy in African Americans,” she said. “So there’s a tremendous need for future studies.”
