Sleep Quality and Anxiety and Depression in Patients with Chronic Obstructive Pulmonary Disease and Their Influencing Factors: a Multicenter Cross-sectional Study

Abstract

Background Respiratory problems in chronic obstructive pulmonary disease (COPD) patients are prone to poor sleep quality, anxiety and depression, but they are often ignored by medical staff and patients themselves. Understanding the sleep quality, anxiety and depression symptoms of patients with COPD and their influencing factors can help to improve the quality of life of patients, however, there are few relevant studies. Objective To investigate the sleep quality, anxiety and depression of patients with COPD and explore the influencing factors. Methods Convenience sampling was used to recruit COPD patients who visited the Department Respiratory Diseases and Critical Care Medicine of seven hospitals in Anhui Province from August to November 2022. Demographic characteristics, dyspnea grade, airflow restriction severity, risk of malnutrition, physical activity level, vaccination, and acute exacerbations in the last 1 year were collected. The Pittsburgh Sleep Quality Index (PSQI) and the Hospital Anxiety and Depression Scale (HADS) were used to evaluate the sleep quality and anxiety and depression symptoms of COPD patients, and the influencing factors were analyzed by multivariate Logistic regression. Results A total of 248 patients with COPD were investigated, among which the incidence of poor sleep quality was 60.9% (151/248), only 8.9% (22/248) of the patients thought they had good sleep quality, and more than half of the patients actually had insufficient sleep time (54.4%) or low sleep efficiency (60.1%). 29.4% (73/248) of COPD patients had at least one of the symptoms of anxiety or depression, of which 35 had anxiety symptoms, 61 had depression symptoms, and 23 had both anxiety and depression symptoms. Multivariate Logistic regression analysis showed that older ages (OR=1.052, 95%CI=1.018-1.086) and risk of malnutrition (OR=3.393, 95%CI=1.855-6.206) were risk factors for poor sleep quality in COPD patients. Regular physical activity was a protective factor for poor sleep quality in COPD patients (OR=0.450, 95%CI=0.242-0.834) (P<0.05). Acute exacerbations ≥2 times (OR=2.220, 95%CI=1.093-4.510) and malnutrition risk (OR=1.961, 95%CI=1.044-3.683) were risk factors for anxiety and depression symptoms in COPD patients (P<0.04). In COPD patients, PSQI score was positively correlated with HADS-A (rs=0.413) and HADS-D score (rs=0.430), and there was a positive correlation between HADS-A score and HADS-D score (rs=0.719, P<0.05) . Conclusion The incidence of poor sleep quality, anxiety and depression symptoms was high in COPD patients, and age, malnutrition risk, regular physical activity and number of acute exacerbations in the past year are important influencing factors. Medical staff, family members and patients themselves should improve the awareness of sleep quality, anxiety and depression, and actively carry out screening and intervention work for key patients to improve the sleep quality and mental health of patients.
