Objetive: To determine the prevalence of asthma and severity of symptoms as risk indicators in school population in cities in various states of Mexico. Material and method: A descriptive study of detection of asthma prevalence and analytical-comparative observational study of determination of symptoms of asthma. The surveys were applied to preschool, elementary, middle and high school population, in the cities of Puebla, Puebla; Tulancingo, Hidalgo; Tlaxcala, Tlaxcala, and Cancún, Quintana Roo; new validated questionnaire was used as instrument: Asthma Diagnostic Questionnaire for Epidemiologic Studies, consisting of eight questions with summation value for diagnosis. Results: 8,754 surveys showed a 14% prevalence in Puebla, 17% in Tulancingo, 7% in Tlaxcala, and 14% in Cancún; average in four cities surveyed was 13%; the strength of association with asthma symptoms in descending order with significant odds ratio were: recurrent wheezing, breathlessness, chest tightness, recurrent cough, cough cold, recurrent cold symptoms, predominantly nocturnal cough, cough that increases with exercise.
