Study: Food Allergies More Common in Older Siblings
According to a new study, older siblings are more likely to suffer from food allergies than their younger brothers and sisters.
Among the participants in the study, food allergies were found in 4 percent of firstborn children, 3.5 percent in second-born children and 2.6 percent in the younger siblings.
The study also found that firstborns are also more likely to have allergic rhinitis and conjunctivitis.
The findings are based on surveys of more than 13,000 children, from the ages of 7 to 15.
The study was presented at the annual meeting of the American Academy of Allergy, Asthma and Immunology.
