Abstract

BackgroundTuberculosis (TB) survivors experience post-TB lung damage and ventilatory function disorders. However, the proportions of obstructive and restrictive ventilatory disorders as well as normal ventilation among post-TB subjects are unknown. In addition, the impacts of ventilatory disorder and its severity on respiratory symptoms, physical activity limitations, and the quality of life in post-TB subjects remain unclear.MethodsSubjects who participated in the Korean National Health and Nutritional Examination Survey 2007–2016 were enrolled in this study. We evaluated the impact of each ventilatory disorder and its severity on respiratory symptoms, physical activity limitations, and quality of life (measured by the EuroQoL five dimensions questionnaire [EQ-5D] index values) in post-TB subjects.Results Among 1,466 post-TB subjects, 29% and 16% had obstructive ventilatory disorders and restrictive ventilatory disorders, respectively. Mild and moderate obstructive ventilatory disorders were not associated with respiratory symptoms, physical activity limitation, or EQ-5D index value compared with normal ventilation; however, severe obstructive ventilatory disorders were associated with more respiratory symptoms (adjusted odds ratio [aOR] = 5.82, 95% confidence interval [CI] = 2.80–12.10), more physical activity limitation (aOR = 92.20, 95% CI = 16.33–520.62), and decreased EQ-5D index (adjusted coefficient = -0.055, 95% CI = -0.096 – -0.013) compared with normal ventilation. Mild restrictive ventilatory disorders were associated with more respiratory symptoms (aOR = 1.95, 95% CI = 1.07–3.56) compared with normal ventilation, while moderate (aOR = 9.17, 95% CI = 1.02–82.22) and severe restrictive symptoms (aOR = 9.17, 95% CI = 1.02–82.22) were associated with physical activity limitation compared with normal ventilation.ConclusionAmong post-TB subjects, 29% and 16% developed obstructive and restrictive ventilatory disorders, respectively. Severe obstructive ventilatory disorder was associated with more respiratory symptoms, more physical activity limitation, and poorer quality of life, while severe restrictive ventilatory disorder was associated with more physical activity limitations.
