Background: The prevalence of childhood asthma has increased dramatically throughout the world over the past 3-4 decades. Asthma has a wide range of risk factors including genetic factors, environmental and lifestyle factors. Due to the different outbreaks of asthma in different parts of the world, even in different cities of a country, it can be attributed to difference in the prevalence of asthma risk factors in different parts of the world. The aim of this study was to evaluate the frequency of inciting and inducing asthma factors in children referred to the clinic of Hazrat Ali-Asghar Hospital in Tehran and to introduce these factors to their parents and society in order to prevent exposure to them. Consequently, this might help reduce the prevalence of asthma and even symptoms of the disease and improve the quality of life of the patients. Method: This descriptive cross-sectional study was conducted in Tehran. All the children aged from 1 to 18 years' old who had been diagnosed with asthma and referred to educational clinic of Hazrat Ali-Asghar hospital from March 2017-2018 were recruited in this study. The method of performing this study was to distribute a self-administered checklist to children parents. Data such as age, sex and inciting and inducing factors of asthma were evaluated and questioned. This study was approved by the IUMS Committee of Ethics. Data were analyzed using SPSS software version 24. Result: One hundred asthmatic children entered the study, of which 67% were boys. The mean age of patients was 66.1 ± 37 months. Inciting factors were respectively pulmonary infection (90%), exposure to cold weather (74%), exercise and intense activity (65%), fast food consumption (53%), history of hospitalization due to Pulmonary infection (52%), sinusitis and adenoid hypertrophy (44%) and allergic rhinitis (38%). Inducing factors for asthma included atopic dermatitis, positive family history in first-degree relatives and contact with detergents (37%), exposure to cigarette smoke at home (35%), having a pet (22%), preterm birth (16%), contact with dust (house renewal) and mites (13%), and maternal smoking during pregnancy (1%). Conclusion: Given the awareness of inciting and inducing factors of asthma, it may be possible to prevent asthma attacks in these patients, as well as identify those who are at increased risk for the disease and prevent or delay the onset of the disease. |
