Quality of sleep among patients diagnosed with tuberculosis—a cross-sectional study

Purpose Tuberculosis (TB) can affect sleep and can predispose patients to chronic diseases like diabetes mellitus. On the other hand, sleep deprivation and diabetes mellitus can worsen tuberculosis. The aim of this study was to assess sleep quality, to estimate the prevalence of poor sleepers and those at risk for restless legs syndrome (RLS) and to evaluate the knowledge and practices regarding sleep hygiene among patients diagnosed with TB. Methods In a cross-sectional study, a semi-structured questionnaire was administered to patients diagnosed with TB in Bengaluru, India. The questionnaire was comprised of sections including demography, knowledge and practice regarding sleep hygiene, the international restless leg study group consensus diagnostic criteria to diagnose RLS, the Pittsburgh sleep quality index, the Epworth sleepiness scale, and history of adverse drug reactions (ADRs). Results Of 206 participants enrolled, 125 men (61%), mean (SD) age was 41.0 (16.2) years, and 121 (59%) had pulmonary TB while the remaining 85 (41%) had extrapulmonary TB. The prevalence (95% confidence intervals) of poor quality sleepers was 17% (12, 23%), those with poor knowledge of sleep hygiene (
