Abstract
Background: Asthma is the most important chronic disease in children and one of the causes of school absenteeism, which is getting more prevalent by the increase of environmental pollutants and industrial life. This study was planned and performed to estimate the prevalence of asthma and other allergic diseases.
Materials and Methods: This cross-sectional study was conducted in 2009 on 3000 female and male students of first grade of guidance school, who were selected by multistage sampling. Data were collected by standard questionnaire and after data collection and entering ISSAC SPSS software the prevalence of asthma and allergic diseases was estimated. Statistical analysis was performed using χ2 statistical test at significance level of 0.05.
Results: Prevalence of asthma, hives, eczema and atopic disease was respectively 3.8 percent, 10.4%, 18.3% and 42%. Prevalence of hives, eczema, atopic disease, watery eyes and wheezing after exercise in both genders showed a statistically significant difference (p <0.05), but asthma, hay fever, speaking difficulty, runny nose and dry cough in both genders had no significant difference (p>0.05)
Conclusion: The results of this study indicated that although the prevalence of asthma in Shirazi children is less than some other cities, the increased development of disease in recent years will be a threatening risk and this phenomenon requires serious attention and planning by authorities as well as health policymakers.
