Abstract

in English, Spanish

BACKGROUND:

Asthma is a chronic inflammatory airway disease whose prevalence has increased, especially in developed countries; the results of studies of asthma prevalence vary in different populations and even within the same country; in Mexico we observed fluctuations in prevalence of asthma from 7% to 33%.

OBJECTIVE:

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.

CONCLUSIONS:

The average prevalence of asthma in the surveyed cities was 13% and the main symptoms indicators of risk of asthma in school children were: recurrent wheezing, breathlessness, chest tightness and recurrent cough.
