Increase in Prevalence of Peanut AllergyAccording to the Food Allergy and Anaphylaxis Network (FAAN), a recent study shows that incidents of peanut allergy in children are rapidly growing, prompting the need for vastly improved standards of care and greater public education. The study, published in the December 2003 issue of Journal of Allergy and Clinical Immunology (JACI), revealed that the incidents of peanut allergy in children doubled over a five-year period. Researchers from the David Hide Asthma and Allergy Research Centre in the Isle of Wight, United Kingdom, tested 1,273 children born between September 1, 1994, and August 31, 1996. A questionnaire, completed by the parents, was used to seek information on past and current atopic symptoms such as asthma, hay fever, and eczema, as well as specific questions relating to food allergy, including peanut allergy, and any anaphylactic reactions. This was then followed by a skin prick test to determine if there is a positive response to peanut. To determine a possible increase in prevalence, the results of the study were compared to a similar study from 1989. The result showed that out of 1,246 children, 3.3% (41 children) had a positive response to peanut during the skin prick test. This is definitely higher compared with the positive response rate of 1.1% in the 1989 study. In addition, children who tested positive to peanut allergy showed a high level of atopy, which is the genetic tendency to develop allergy and asthma symptoms. Based on the responses from the questionnaire, there was also an increase in reported peanut allergy, from 0.5% to 1.0%.
Cause & TreatmentScientists believed that there are several reasons for this, including:
- Consumption of peanuts of women during pregnancy
- Infants exposed to peanut through breast milk, which may contain major peanut allergens
- An increase in the number of families who become vegetarian or supplement their diet with vegetarian foods, often containing nuts, particularly peanuts
