ObjectiveTo analyze the relationship between medication compliance of patients with uncontrolled asthma and lung function,airway inflammation level, asthma control level and quality of life so as to obtain important references for improving patient compliance and asthma control level in the future. MethodsQuestionnaires were performed in asthma patients who did not achieve asthma control and had poor compliance in 32 third-class hospitals in 28 provinces of China mainland. All patients were tested for lung function and airway inflammation levels. So the relevant data of asthma compliance was investigated and analyzed. ResultsA total of 923 patients were investigated and the questionnaire recovery rate was 100%. Two hundred and forty-three (26.33%) answered cognitive related questions about asthma completely correctly. Treatment compliance in asthma patients was positively correlated with lung function and significantly negatively correlated with exhaled nitric oxide. Better treatment compliance in asthma has higher level of asthma control and quality of life. Poor compliance in asthma patients will lead to decreased lung function and elevated levels of airway inflammation, resulting in decreased asthma control and quality of life. ConclusionAsthma treatment compliance is related to lung function, airway inflammation, asthma control level and quality of life.
