摘　　要：The number of people with food allergy(FA)has increased in recent decades,as has the number of foods to which they are allergic.Estimates of FA prevalence vary widely,likely because of different definitions,evaluated foods and geo-graphic variations.In developed countries,overall preva-lence estimates range from 1.9%to 7.2%[1,2].In Latin America,the prevalence of FA in children is between 1.4%and 5.3%[3-6],with important age-based variations(from 1.9%in infants to 0.4%in preschoolers)[7].FA is a complex trait in which the interplay of genetic and environmental fac-tors results in disease expression.Well-known factors that increase atopic susceptibility include sex[8,9],age[10],and socioeconomic status[11-13].Furthermore,the asso-ciation between family history of allergies and childhood FA has been consistently reported in recent years.Overall,a maternal history of allergic disease appears to be more strongly associated with FA than paternal history of atopy[14].
