Risk Factors Of Development And Acute Attack Asthma In Children

Objective:To analyze the risk factors of development and acute attack asthma in children,to provide reference material for the clinical prevention and treatment of childhood asthma.Methods:The asthma group(312cases)was selected from a pool of inbound patients to our Pediatric Ward diagnosed with asthma between September 1,2014 and September 30,2016.,the control group(312cases)consisted of patients selected from the same ward and period,diagnosed with non-asthma repertory infections without any history of wheezing or any other symptoms,The subjects are then surveyed via telephone interviews as well as questionnaires regarding the asthma patients'general condition,to analyze the risk factors and etiology of acute episodes for asthmaResults:(1)75.65%of all first-time diagnosis of asthma takes place under the age of 3,the frequency of diagnosis decreases incrementally after age 6.However,there are no statistical differences regarding the first incidence of asthma between ethnic Han Chinese and ethnic Korean minorities.(2)Single factor Logistic regression analysis demonstrated that artificial feeding,improper cesarean section and preterm birth were risk factors that contributed to asthma.(3)Among asthma group,89.7%of the instances of acute attack of asthma were caused by respiratory tract infection,emotional instability(such as crying)and exposure to airborne irritants(such as fresh paint)accounted for 4.2%.Last but not least,unknown causes of asthma accounted for 6.1%.(4)The asthma group with respiratory tract infection,viruses infections,mycoplasma infections and bacterial infections accounted for 61.1%,22.5%and 16.4%.There were significant variances between viral infection and bacterial infection,or viral and mycoplasma infection at(P<0.05).However,there were no significant difference between bacterial infection and mycoplasma infection.The average days of hospitalization is significantly higher in asthma patients with respiratory tract infection compared with the control group(3.89±1.454 vs 5.47±2.091,P<0.05).There were significant difference of the average hospitalization days in children with severe asthma attact compared with those mildly and moderately affected(P<0.05).Conclusion:(1)First time diagnosis of asthma takes place during early childhood.(2)Artificial feeding,cesarean delivery and premature birth are risk factors for asthma.To counter these factors,best practices such as vaginal delivery and breastfeeding should be encouraged.(3)The most common causes of acute asthma attack in the region were respiratory infections;most commonly viral,followed by mycoplasma infection.
