We aimed to evaluate on a population basis the parent-reported prevalence of FA and its clinical characteristics in Mexican schoolchildren. MethodsA validated Spanish version of a structured written questionnaire was administered to parents of schoolchildren aged 5–13 years old from Culiacan, Mexico. ResultsA 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. ConclusionsThe 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. ER -
