Abstract
Sleep is a normal and vital physiological phenomenon to lead a normal and quality livelihood. Approximately 7-8 hours of sleep is essential for maintaining a healthy life. Chronic sleep deprivation affects the physical function, cognitive function of humans and also jeopardizes the quality of life. Several factors like chronic disease conditions, anxiety, depression leads to sleep deprivation. Tuberculosis is a chronic disease condition, where the patients’ suffer from co morbid depression and anxiety and ultimately may lead to sleep deprivation. Several studies have postulated the prevalence of co morbid depression and anxiety among tuberculosis patients’ but there exist a paucity of literature about the quality of sleep among tuberculosis patients’. This prospective observational study aims to assess the quality of sleep among tuberculosis patients’ in relation to their co morbid depression and anxiety using Beck Depression, Beck Anxiety and Pittsburg Sleep Quality Index scales. The average value of PSQI in our study cohorts was found to be 6.92 ± 1.5. Also there exists a strong positive correlation (r= 0.277) between anxiety and depression level, as well as between quality of sleep and depression (r= 0.684, (p<0.001)) and anxiety level (r= 0.340, (p<0.001)) of the patient. Patients’ with chronic disease conditions are highly susceptible to emotional disturbances like depression, and anxiety, which impairs the quality of sleep. Our study which aims in assessing the quality of sleep among tuberculosis patients’ demonstrated that the quality of sleep reduces significantly with associated depression and anxiety level of the patients’.
