Mental health problems, obstructive lung disease and lung function: findings from the general population

Area of Science:

• Pulmonary Medicine
• Psychiatry
• Epidemiology

Background:

• Obstructive lung diseases (asthma, COPD) are associated with poor mental health.
• Existing research lacks studies linking mental health to objective lung function measures like spirometry.

Purpose of the Study:

• To investigate the relationship between obstructive lung disease, spirometrically defined airway obstruction, and mental health problems in a general population sample.

Main Methods:

• A structured interview assessed psychopathological syndromes in 1772 adults.
• Participants underwent spirometry and reported on obstructive lung disease history.
• Logistic and linear regression models analyzed the associations.

Main Results:

• 35.7% of participants reported mental health problems.
• Asthma and chronic bronchitis were linked to most mental health domains.
• Spirometric airflow limitation was independently associated with generalized anxiety (ORs 2.3-2.7).
• Reduced FEV1/FVC ratio correlated with general mental health issues, panic, and generalized anxiety.

Conclusions:

• Objective airflow limitation is associated with generalized anxiety and panic.
• The causal link between lung disease, airflow limitation, and anxiety requires further study.
• Clinicians should consider the overlap between obstructive lung disease and anxiety disorders.
