The Impact of Anxiety/Depression on the Efficacy of Asthma Control Drugs and the Construction of a Predictive Model for the Risk of Acute Asthma Attacks

Conditions studied

Anxiety/Depression and Asthma

About this study

The goal of this clinical trial is to explore the impact of anxiety/depression on the efficacy of asthma controller medications and to develop a risk prediction model for asthma acute exacerbations in patients with asthma. It will also analyze the association between anxiety/depression severity and asthma severity. The main questions it aims to answer are: Does anxiety/depression affect the therapeutic effect of asthma controller medications (e.g., asthma control level)? Can a reliable risk prediction model for asthma acute exacerbations be established based on anxiety/depression and other relevant factors? Researchers will conduct a prospective observational study to collect and analyze data from participants, without additional interventions beyond standard clinical care, to explore the above research questions. Participants will: Complete baseline assessments, including demographic information collection, medical history review, lung function tests, anxiety/depression evaluations (via GAD-7 and PHQ-9 scales), and provide biological samples (induced sputum, feces, blood) Undergo follow-up visits at 3, 6, 12, 18, and 24 months after baseline Report asthma symptoms, acute exacerbation events, and cooperate with required clinical checkups during follow-up
