It severely affects the physical and mental health of children and imposes a huge economic burden on families and society, consuming a large amount of medical and health resources. In recent years, the prevalence of asthma in children worldwide has generally continued to rise. Data from the Global Burden of Disease database in 2019 showed that the prevalence of asthma in children aged 0-9 years was 4.21%, in children aged 10-14 years was 4.10%, and in adolescents aged 15-19 years was 3.00%. In China, over the past 20 years, the prevalence of asthma in children has also shown an overall upward trend, increasing from 0.91% in 1990 to 1.54% in 2000, and then to 3.02% in 2010. Thanks to the continuous efforts of several generations of pediatricians, the level of standardized diagnosis and treatment of childhood asthma has significantly improved. However, the control of asthma in children still faces many challenges.\n\nThe purpose of this study is to comprehensively understand the disease control and management status of children with asthma in China, as well as the types of airway inflammation. The findings of this survey will help improve the asthma control level in Chinese children, facilitate future patient education, guide rational medication use, and provide important evidence for health decision-making departments to better allocate and utilize medical resources.","Children aged 2-18 years and diagnosed with asthma ≥3 months were enrolled in the study.",[23],{"type":6,"name":24,"description":24,"armGroupLabels":16,"otherNames":16},"Questionnaire and Physical Exam",[26],{"name":27,"role":28,"phone":29,"phoneExt":16,"email":30},"Peng Han, Doctor","CONTACT","+86-18612935979","hanpengonly1@163.com",{"type":32,"investigatorFullName":33,"investigatorTitle":34,"investigatorAffiliation":35,"oldNameTitle":16,"oldOrganization":16},"PRINCIPAL_INVESTIGATOR","Kunling Shen","Professior","Shenzhen Children's Hospital","100580460",false,"NCT06837584","Control and Treatment of Outpatient Children With Asthma","A Multicenter Observational Study on the Current Status of Control and Treatment of Outpatient Children With Asthma and the Types of Airway Inflammation","Inclusion Criteria:\n\n* Age between 2 and 18 years old\n* Diagnosed with asthma for more than 3 months\n* Had asthma symptoms or asthma treatment within the past 12 months.\n\nExclusion Criteria:\n\n* With other respiratory diseases such as bronchiectasis, bronchiolitis, cystic fibrosis, and pneumonia\n* Have participated in any interventional clinical studies related to asthma within the 3 months prior to enrollment in this study\n* Parents, legal representatives, or guardians do not agree to participate in this study.","ALL","2 Years","18 Years",{"count":46,"type":47},42000,"ESTIMATED","OBSERVATIONAL","The aim of this study is to comprehensively understand the disease control and management status of children with asthma in China, as well as the types of airway inflammation.
