Summary
Poor sleep quality is common in patients with chronic obstructive pulmonary disease (COPD). Factors like arterial hypertension, chronic sputum, and more severe disease stages significantly worsen sleep quality in these individuals.
Area of Science:
- Pulmonary Medicine
- Sleep Medicine
- Clinical Research
Background:
- Chronic obstructive pulmonary disease (COPD) is frequently associated with patient-reported poor sleep quality.
- The specific factors contributing to sleep disturbances in COPD patients remain incompletely understood.
- Identifying these factors is crucial for improving patient outcomes.
Purpose of the Study:
- To determine the prevalence of poor sleep quality in COPD patients.
- To investigate demographic, clinical, and spirometric factors associated with impaired sleep quality in this population.
Main Methods:
- A descriptive, cross-sectional study was conducted with 100 COPD patients.
- Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), with a score ≥5 indicating poor sleep quality.
- Data on demographics, comorbidities (including arterial hypertension), symptoms (chronic sputum, CAT score), and spirometry (GOLD stage, FEV1) were collected.
Main Results:
- 63% of COPD patients experienced poor sleep quality (mean PSQI score 6.59).
- Poor sleep quality was significantly associated with arterial hypertension, chronic sputum, higher COPD Assessment Test (CAT) scores, and GOLD stage 4.
- Lower forced expiratory volume in 1 second (FEV1) and other spirometric data also correlated with impaired sleep.
Conclusions:
- Poor sleep quality is highly prevalent in COPD patients.
- Sleep disturbances are linked to more severe COPD and specific comorbidities.
- Early identification and treatment of sleep disorders are recommended for COPD management.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

2.7K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
