Relationship between sleep quality and mental health according to demographics of 850 patients with chronic obstructive pulmonary disease.

We aimed to study sleep problems in hospitalized chronic obstructive pulmonary disease patients and assess the relationship of sleep quality with mental health and demographics of patients. Our study sample consisted of 850 chronic obstructive pulmonary disease patients hospitalized in Masih Daneshvari Hospital. Demographic data were collected and the Pittsburgh Sleep Quality and mental health questionnaires were filled out for patients. The results showed that 5.9 percent were suffering from severe sleep problems, while 4.7 percent had severe mental problems. A strong positive correlation was found between the total scores of mental health and sleep quality (p < 0.01). The prevalence of sleep and mental health problems was higher in females compared to males. Mental health and sleep quality play important roles in quality of life of chronic obstructive pulmonary disease patients. [ABSTRACT FROM AUTHOR]
