Objective:
The relationship between depression severity and cough, wheeze and exertional dyspnoea is unclear. The aim of this study was to explore this relationship.
Methods:
We used weighted logistic regression analysis and fitted curves to explore the relationship between depression severity and respiratory symptoms. In addition, we examined the relationship between depression and COPD and asthma. Stratified analyses were used to analyse specific populations.
Results:
We weighted 10,142 subjects to reflect the entire US population. Using the population without depression as a reference, the risk of cough and asthma in the severely depressed population was 3.32 times (OR 3.324, 95% CI 1.567-7.050) and 2.84 times (OR 2.842, 95% CI 1.521-5.311) higher than that in the population without depressive symptoms, and the risk of asthma and COPD was 2.4 times and 2.6 times (OR 2.410, 95% CI 1.371-4.236; OR 2.566, 95% CI 1.236-4.921). In subgroup analyses, the correlation between depression scores and prevalence of cough and wheeze was corrected for gender level. In addition, smoking status and marital status were interaction factors between depression score and prevalence of cough. The prevalence of exertional dyspnoea by depression score was influenced by CVD.
Conclusions:
Depression severity was associated with respiratory symptoms, asthma, and COPD. Gender corrected the correlation between depression and cough and asthma, and depressive state was an independent risk factor for asthma and COPD. This finding provides new ideas for the management of respiratory symptoms and diseases.
