Abstract:

Objective To investigate the effect of age,period,cohort and geographical space on the incidence and death of pulmonary tuberculosis,and to provide a reference basis for tuberculosis prevention and treatment efforts in China. Methods Age-period-cohort model was used to analyze changes in incidence and mortality of tuberculosis by age,period and cohort,and spatial statistical method was used to explore the spatial clustering of tuberculosis incidence and death. Results From 2005 to 2019,the incidence and mortality of pulmonary tuberculosis in China showed a decreasing trend year by year. The analysis results of age-period-cohort(APC) model showed that the incidence and mortality of pulmonary tuberculosis in Chinese people aged 10 years and older increased with age,and the incidence increased from 54.552/100 000 in the group aged 10-<15 years to 2 688.965/100 000 in the group aged ≥85 years(χ2trend=1495.365,P<0.01),the mortality rate increased from 0.063/100 000 in the 10-<15 year old group to 46.882/100 000 in the ≥85 years group(χ2trend=640.712,P<0.01). Using 2010-2014 as the reference group,the rate ratio(RR) values of incidence and mortality of pulmonary tuberculosis among people aged 10 years and over in China showed a decreasing trend with the advance of time in 2005-2009 and 2015-2019. Using the 1965-1969 cohort as a reference,the RR for pulmonary tuberculosis incidence and mortality was significantly higher in those born before 1965 compared with those born after 1969,with increasing RR for incidence and mortality in those born 1934 and before,peaking in those born 1930-1934. Geographic information system(GIS) analysis results showed spatial clustering of tuberculosis incidence and death in China from 2005 to 2019,with Moran's >0 and Z>1.96,P<0.05. Local autocorrelation results showed that high tuberculosis incidence and mortality were concentrated in Xinjiang Uygur Autonomous Region and Xizang Autonomous Region,and low-low incidence was concentrated in the east and central regions. Conclusion Age-period-cohort is important factors affecting the incidence and mortality of tuberculosis,and there is a spatially clustering in the tuberculosis incidence and death. Therefore,it is necessary to increase screening of the elderly population,conduct tuberculosis knowledge campaigns,and increase the awareness rate of population health knowledge,while increasing economic aids in Xizang Autonomous Region and Xinjiang Uygur Autonomous Region to promote equity and accessibility in health resource allocation and protect population health.
