In our study, we found that peanut allergy was reported most often among 6- to 10-year-old children (25.5%), white children (47.7%), and children from households with an annual income of $50,000-$99,999 (41.7%). Although peanut allergy was diagnosed by a physician in roughly 75% of cases, the reactions tended to be more severe than for other foods (53.7% versus 41.0%). Furthermore, parents were significantly less likely to report tolerance to peanut as compared with the odds of tolerance reported for other foods. Therefore, overall, childhood peanut allergy, which represents nearly a quarter of all food allergy, presents more severe reactions and is less likely to be outgrown than other food allergies. Although it is diagnosed by a physician in nearly three-fourths of all cases, socioeconomic disparities remain regarding how it is diagnosed. To learn more about our study, click here.
