title: [Prevalence of rhinitis allergic in populations of several states of Mexico].
abstract: BACKGROUND
  Allergic rhinitis is an inflammatory disorder of the nasal mucosa, characterized by symptoms of itching, rhinorrhea, nasal congestion and sneezing induced by an IgE-mediated response. In Mexico we have reports of prevalence, with fluctuations of 5.5% to 47.7% with the question of rhinitis symptoms the past 12 months.
  
  
  OBJECTIVE
  To determine the prevalence of allergic rhinitis in schoolchildren from various states of Mexico.
  
  
  METHODS
  A descriptive study of prevalence in which a questionnaire was applied to preschool, elementary-, middle- and high-school population. It was performed in four cities in four states of Mexico: Puebla, Puebla, Tulancingo, Hidalgo, Tlaxcala, Tlaxcala and Cancun, Quintana Roo. Parents answered questionnaires of preschool and elementary school and middle- and high-school students answered their questionnaires. The study was conducted from June 2014 to January 2015. The instrument used was: questionnaire diagnosis of allergic rhinitis for epidemiological studies.
  
  
  RESULTS
  Of the surveys, 8,159 completed questionnaires were obtained, in the city of Puebla: 2,267, Tulancingo, Hidalgo: 2,478, Tlaxcala, Tlaxcala: 2,574, Cancun, Quintana Roo: 840; total male: 4,190 (51%). The overall average rate of prevalence of allergic rhinitis among four states including all respondents ages was 15%.
  
  
  CONCLUSIONS
  With the use of the questionnaire diagnosis of allergic rhinitis for epidemiological studies in the four cities in four different states, we found a prevalence of allergic rhinitis of 15% in ≥13 yearpopulation and 13% in ≤12 year-old children.
