Abstract:
Objective :To analyze the epidemiological characteristics of tuberculosis in Urumqi and assess the im⁃pact of the national health examination policy , as well as COVID⁃19 prevention and control measures , on tuberculo⁃sis incidence in Xinjiang.
Methods:The seasonal patterns of pulmonary tuberculosis were examined using the seasonal index method and circular distribution analysis. An Interrupted Time Series (ITS , Interrupted Time Series) model was employed to investigate how the national health examination policy and COVID_19 interventions influenced trends in tuberculosis incidence in Urumqi.
Results:From 2013 to 2021 , a total of 19 ,049 cases of tuberculosis were reported in Urumqi. The peak incidence day occurred on May 25th , indicating a consistently high rate throughout the year, particularly during spring and summer months. The results of the interrupted time series model indicated that the initial monthly incidence rate of pulmonary tuberculosis in Urumqi was 5. 05 per 100 ,000. From January 2013 to September 2016 , the incidence rate of pulmonary tuberculosis showed a slow upward trend , and the upward trend was significant (β1 = 0. 039 ,P < 0. 05) . After the implementation of the universal health checkup policy , the incidence rate of pulmonary tuberculosis showed a slow downward trend , and the downward trend was significant(β3 = - 0. 109 ,P < 0. 05) . After the outbreak of the COVID_19 epidemic in January 2020 , the incidence rate of pulmonary tuberculosis in Urumqi first dropped rapidly and then entered a slow upward stage , and the upward trend was significant(β5 = 0. 082 , P < 0. 05) .
Conclusion :It is recommended that public health authorities prioritize timely identification of potential TB patients during periods with elevated incidence rates observed in spring and summer months. While significant progress has been made through implementing national health examinations policies , attention must be directed towards understanding how ongoing epidemics affect TB patient detection. Thus , enhancing surveillance efforts and intervention strategies are essential in adapting to this new normal.
