Assessment Of Sleep Quality and Its Impact on Health-Related Quality of Life in Treated Tuberculosis Patients in A Tertiary Care Centre, Chengalpattu District

Introduction: Tuberculosis (TB) can cause persistent symptoms, such as sleep disturbances, even after treatment, significantly reducing the patient’s quality of life. As good sleep is vital for overall health, early identification and management of poor sleep quality are essential for improving long-term outcomes in TB survivors. Aim: To determine the sleep quality among treated TB patients and to assess its impact on health-related quality of life in a tertiary care centre. Methods: A cross-sectional study was conducted involving 60 patients with pulmonary and extrapulmonary TB who completed ATT for 6 months. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and HRQoL was evaluated using the SF-36 Questionnaire. Statistical analyses were performed to determine the correlation between PSQI scores and various HRQoL domains. Results:The mean age was 39.7 years, and 61.7% of patients were male. No significant sex differences were observed (p = 0.254). A total of 35% had poor sleep quality (PSQI > 5), which was significantly more common in those aged > 50 years (p = 0.007). Poor sleepers had notably worse scores in pain, general health, energy/fatigue, and physical functioning (all p < 0.05), with strong negative correlations between PSQI and pain (r = -0.794), physical functioning (r = -0.669), and energy/fatigue (r = -0.635) scores. Conclusion: Sleep disturbances are common among Treated TB patients and are strongly associated with a reduced quality of life. Integrating routine sleep quality screening and psychosocial support into post-treatment care may improve long-term outcomes for TB survivors.
