About this trial
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. The findings of this survey will help improve the asthma control level in Chinese children, facilitate future patient education, and guide rational medication use. Moreover, it will provide important evidence for health decision-making departments to better allocate and utilize medical resources.

Primary outcomes
Asthma control level
The Asthma Control Test (ACT) will be employed for assessment, with the following interpretation criteria: a total score of 20-25 indicates well-controlled asthma, where symptoms are satisfactorily managed and the current treatment regimen should be continued; a score of 16-19 suggests poorly controlled asthma, indicating suboptimal symptom management that requires treatment adjustment or enhanced disease management; and a score of 5-15 reflects very poorly controlled asthma, with severe uncontrolled symptoms necessitating immediate medical attention and treatment modification.
The proportion of type 2 inflammation
Blood EOS and IgE were used to judge. The T2 inflammatory phenotypes were classified based on blood eosinophil count and total specific IgE levels: Only-atopy was defined as blood eosinophils \<300/μL with sum of all specific IgE ≥0.7 kU/L; Only-EOS as blood eosinophils ≥300/μL with sum of all specific IgE \<0.7 kU/L; T2-high as blood eosinophils ≥300/μL with sum of all specific IgE ≥0.7 kU/L; and T2-low as blood eosinophils \<300/μL with sum of all specific IgE \<0.7 kU/L.
