Abstract:
Objeetive:To understand the recurrence of tuberculosis patients in Yunnan Province and its influencing factors,so as to provide scientific basis for the prevention and control of tuberculosis.
Methods:Through the tuberculosis management information system, the data of successful treatment of tuberculosis cases in Yunnan Province in 2013 and the data of recurrent tuberculosis cases in Yunnan Province in 2014-2018 were collected. The recurrence rate,recurrence proportion and recurrence time of tuberculosis were analyzed, and the influencing factors of tuberculosis recurrence were analyzed by Cox multi factor proportional risk model.
Results :A total of 9787 cases of tuberculosis were investigated. 385 cases recurred in 5 years, accounting for 3.94%. The recurrence rate was 0.73/100 person years. The recurrence interval [M （QR）] was 35.12 （28.57） months. The following are the risk factors for pulmonary tuberculosis recurrence：male（HR=1.297,95%CI：1.031~1.631）,secondary tuberculosis(HR=2.000,95%CI：1.088~3.676) in the 40-59 age group（HR=1.618,95%CI：1.036-2.528）, the retreatment（HR=1.566,95%CI：1.040-2.356）,positive of sputum culture（HR=4.048,95%CI：1.795-9.129）and sputum?smear positive（HR=1.569,95%CI：1.266-1.945）, cavitary pulmonary tuberculosis（ HR=1.382,95%CI：1.112-1.716）.
Conclusion:The recurrence rate of tuberculosis is low in Yunnnan province, and the risk of pulmonary tuberculosis recurrence is high in male, in the 40-59 age group,retreatment,positive of sputum culture only and sputum smear positive,patients with cavitary tuberculosis.
