ABSTRACT
BACKGROUND:
Food allergy (FA) prevalence is well documented in developed countries and appears to be increasing, but remains unknown in most Latin American countries. We aimed to evaluate on a population basis the parent-reported prevalence of FA and its clinical characteristics in Mexican schoolchildren.METHODS:
A validated Spanish version of a structured written questionnaire was administered to parents of schoolchildren aged 5-13 years old from Culiacan, Mexico.RESULTS:
A total of 1049 parents responded to the survey (response rate, 84%). The estimated prevalence rates (95% CI) were adverse food reactions 10.0% (8.3-11.9), "perceived FA, ever" 5.5% (4.3-7.0), "physician-diagnosed FA, ever" 4.9% (3.7-6.3), "immediate-type FA, ever" 4.4% (3.3-5.8), "immediate-type FA, current" 3.5% (2.6-4.8), and anaphylaxis 1.2% (0.72-2.1). Immediate hypersensitivity reactions were mainly triggered by the consumption of shrimp (1.3%), other shellfish (0.7%), strawberry (0.6%), chocolate (0.5%), and egg (0.4%). Schoolchildren with "immediate-type FA, current" had more atopic dermatitis and allergic rhinitis (p<0.05), but not asthma or drug allergy (p>0.05) than children without FA. All cases of anaphylaxis sought medical attention, but only one child had physician-diagnosed anaphylaxis and was advised to acquire an epinephrine autoinjector.CONCLUSIONS:
The prevalence of "immediate-type FA, current" to any food is 3.5% in Mexican schoolchildren. The poor recognition of anaphylaxis and the low frequency of prescription of epinephrine autoinjectors suggest that acute food-induced allergic reactions are not optimally managed in Mexico.Palabras clave
