Comorbidities are a significant factor affecting the prognosis of patients with rifampicin-resistant tuberculosis (RR-TB). We evaluated the prevalence of comorbidities and their prognostic effects in a Chinese RR-TB cohort. In this study, we reviewed the clinical data of RR-TB patients who started anti-tuberculosis treatment in China between May 2018 and April 2020 by conducting a multicenter cohort study. A log-binomial regression model was used to analyze the relationship between comorbidities and the treatment outcomes of RR-TB. The burden of comorbidities among RR-TB patients in China was heavy, with 49.45% (670/1355) experiencing at least one comorbidity. The most common comorbidities were diabetes (17.79%), followed by other respiratory diseases (11.14%), other liver and kidney diseases (5.31%), hypertension (5.24%), immunodeficiency (4.94%), viral hepatitis or carriers (3.91%), severe heart disease (2.58%), tumours (1.11%), and chronic kidney disease or renal insufficiency (0.74%). Diabetes (RR = 1.31), severe heart disease (RR = 1.70), tumours (RR = 1.89), hypertension (RR = 1.28), aged ≥ 60 years (RR = 1.64) and 45-59 years (RR = 1.38), ethnic minorities (RR = 1.58), retreatment cases (RR = 1.34), and those not using the bedaquiline regimen (RR = 1.92) significantly increased the risk of unfavorable treatment outcomes. While higher education or above (RR = 0.49), employment (RR = 0.51), and having a normal (R = 0.53) or overweight (R = 0.56) BMI could reduce the risk...
