Objective To have a comprehensive understanding of the epidemiological characteristics of extrapulmonary tuberculosis in Tianjin, and provide theoretical evidence for the prevention and control of extrapulmonary tuberculosis. Methods The data of registered extrapulmonary tuberculosis patients in TB management information system from 2015 to 2017 were collected and analyzed by descriptive epidemiological methods. Results A total of 1 190 extrapulmonary tuberculosis patients were registered in Tianjin from 2015 to 2017, accounting for 10.39% of all tuberculosis patients;the average annual incidence was 2.57/105. The main reporting institutions were municipal designated tuberculosis medical institutions. Tuberculous lymphatitis was the most common reported extrapulmonary tuberculosis, accounting for 25.55% of all extrapulmonary tuberculosis cases , followed by osteoarthrosis tuberculosis ( 22.52%) and urogenital tuberculosis (11.26%). Brain, scrofula and intestines, peritoneum, mesenteric gland tuberculosis mostly occurred in teenagers (15 to 25 years old) and the prime group (45 to 55 years old);the incidence of joint tuberculosis and urogenital system tuberculosis increased with age in extrapulmonary TB patients;urogenital system TB frequently occurred in young adults (25 to 55 years old);the proportion of patients with cutaneous tuberculosis among patients with extrapulmonary tuberculosis decreased with age;the HIV screening rate in extrapulmonary tuberculosis decreased year by yea r. Conclusion The reported incidence of extrapulmonary tuberculosis has shown a yearly increasing trend in Tianjin. Municipal designated tuberculosis medical institutions were the main reporting institutions. Relevant departments should strengthen the extrapulmonary tuberculosis registration and HIV screening in patients with extrapulmonary TB, attach importance to the extrapulmonary tuberculosis diagnosis and treatment ability of medical staff in hospitals so as to reduce misdiagnosis of extrapulmonary tuberculosis.
