Abstract

in English, Spanish

BACKGROUND:

Food allergy is deemed to have a worldwide prevalence ranging from 2 to 10 %.

OBJECTIVE:

To determine the frequency of skin reactivity to food allergens by age groups.

METHODS:

Cross-sectional, descriptive, prolective, observational study. Patients aged from 2 to 64 years with symptoms consistent with allergic disease were included. Skin prick tests were carried out with food allergens. Frequencies and percentages were estimated.

RESULTS:

One-hundred and ninety-one patients were included, out of which 63.4% were females. Mean age was 22.5 years; 19.3 % showed positive skin reactivity to at least one food. Distribution by age group was as follows: preschool children 13.5 %, schoolchildren 24.3 %, adolescents 2.7 % and adults 59.5 %. Diagnoses included allergic rhinitis in 84.3 %, asthma in 19.4 %, urticaria in 14.1 % and atopic dermatitis in 8.4 %. Positive skin reactivity frequency distribution in descending order was: soybeans with 5.2 %, peach with 4.7 %, grapes, orange and apple with 3.6 %, nuts with 3.1 %, pineapple, avocado, tomato and tuna with 2.6 %.

CONCLUSION:

The frequency of skin reactivity to food allergens was similar to that reported in the national and Latin American literature, but sensitization to each specific allergen varied for each age group.
