[The results of using a simplified questionnaire for determining the prevalence of bronchial asthma].
The aim of the study was to assign the asthma prevalence in a Romanian region, by using a simplified questionnaire, easy to fill in by every subject without specialized help. The study included 508 subjects, 280 women (55.1%) and 238 men (44.9%). The subjects proceeded from different industrial areas (cement factory, rubber processing factory, fur and leather manufacture) and from a village (214 subjects). 203 subjects, having symptoms compatible with asthma, performed lung function tests with a Flow Screen Jaeger device, determining VC, FEV1, FEV1% VC, MEF50, MEF25, and pharmacodynamic test if needed (bronchoconstrictor or bronchodilator).


RESULTS
about 40% of the subjects mentioned the wheezing, among them 18% wheezing and dyspnea. "Asthmatic bronchitis" is present at 14.8% of the subjects, including 4.5% patients with bronchial asthma diagnosed by a physician (underdiagnosis). The asthma symptoms are more frequent in the factories with exposure to inhaled allergens and air pollution. The most discriminative symptom association for asthma was: wheezing and breathlessness and a history of dyspnea in the last year. These symptoms suggest that the prevalence of asthma could be 10.43%. The positive bronchodilator or bronchoconstrictor function test associated with wheezing, present at 7.48% of the population, seems to better evaluate the prevalence of asthma, which approaches other data already published. The questionnaire we used proved that it can select with acceptable accuracy the individuals to be further investigated with lung function tests.
