Background People with pulmonary tuberculosis are at risk of developing chronic respiratory disorders due to residual lung damage. To date, the scope of the problem in high-burden tuberculosis countries is relatively unknown. Methods Chronic respiratory symptoms (cough and phlegm lasting >2 weeks) and radiological lung abnormalities were compared between adults with and without a history of tuberculosis among the general population of Uganda. Multivariable regression models were used to estimate odds ratios (ORs) with adjustment for age, gender, smoking, education, setting, and region. Random effects models accounted for village clustering effect. Results Of 45293 invited people from 70 villages, 41154 (90.9%) participated in the survey. A total of 798 had a history of tuberculosis and, among them, 16% had respiratory symptoms and 41% X-ray abnormalities. Adjusted ORs showed strong evidence for individuals with a history of tuberculosis having increased risk of respiratory symptoms (OR, 4.02; 95% confidence interval [CI], 3.25–4.96) and X-ray abnormalities (OR, 17.52; 95% CI, 14.76–20.79), attributing 6% and 24% of the respective population risks. Conclusions In Uganda, a history of tuberculosis was a strong predictor of respiratory symptoms and lung abnormalities, before older age and smoking. Eliminating tuberculosis disease could reduce the prevalence of chronic respiratory symptoms as much as eliminating smoking. [ABSTRACT FROM AUTHOR]
