title: [High prevalence of food sensitization among adults with allergic diseases who live in the Guadalajara metropolitan area].
abstract: The prevalence of food sensitization in adults shows differences owing to geographic, regional and cultural circumstances.
  
  
  
  To identify the prevalence and factors associated with food sensitization in adults with allergic diseases.
  
  
  
  Cross-sectional study, where medical records of adult patients with any allergic disease and who tested positive to airborne allergens on at least one skin test were reviewed. Age, sex, underlying allergic disease and skin test result were recorded. Statistical analyses included food sensitization prevalence with the corresponding 95 % confidence intervals (CI), as well as a multivariate analysis to determine associated factors.
  
  
  
  We included 258 patients with a mean of 36 years of age; 75 % were of the female sex. The most common underlying condition was allergic rhinitis (59 %). The prevalence of food sensitization was 37 % (95 % CI, 31.5-43.3) and it did not vary significantly according to sex or allergic disease in question. The most sensitizing food was soybeans (44.8 %), and associated factors were sensitization to cat dander (OR = 1.8; 95 % CI, 1.03-3.2) and 5 or more positive skin tests (OR = 4.3, 95 % CI 2.3-8.1).
  
  
  
  The prevalence of food sensitization in people with allergic disease was 40 %. Further studies are required to determine its prevalence in the general population.
