Epidemiological characteristics of pulmonary tuberculosis in Sihui City from 2018 to 2022
Objective To analyze the epidemiological characteristics of pulmonary tuberculosis(PTB)in Sihui City of Guangdong Province,and to provide basis for PTB control and prevention.Methods The reported incidence data of PTB by region,age and population in Sihui City from 2018 to 2022 according to the new admission date were collected through the Infectious Disease Reporting Information System of the China Information System for Disease Control and Prevention.The epidemiological characteristics of PTB in Sihui City from 2018 to 2022 were analyzed by Excel 2013 and SPSS 18.0 software.The reported incidence rates and the composition ratios were compared by Chi-square test,and the change trend was analyzed by trend Chi-square test.The test level wasα=0.05.Results A total of 1 086 PTB cases were reported in Sihui City from 2018 to 2022,with an annual average reported incidence of 46.45/105,and the reported incidence decreased from 45.70/105 in 2018 to 40.78/105 in 2022,with an average annual reduction rate of 2.81％.The reported incidence showed a decreasing trend year by year(x2trend=5.611,P=0.018).The annual average reported incidence of males(66.89/105)was higher than that of females(24.26/105),and the difference was statistically significant(x2=228.308,P＜0.001).The age distribution was mainly 25-34 years old and 45-69 years old.The main occupations were farmers(33.43％),domestic work or unemployed population(23.85％)and workers(12.71％),accounting for 69.98％(760/1 086)of all cases.The annual average reported incidence rates were significantly different among different streets and towns(x2=174.187,P＜0.001).The highest incidence rate was in Dongcheng Street(66.22/105),followed by Chengzhong Street(61.56/105).The annual average reported incidence of central urban areas(63.91/105)was higher than that of rural towns(29.68/105),and the difference was statistically significant(x2=147.323,P＜0.001).Conclusions In recent years,the reported incidence of PTB in Sihui City had shown a decreasing trend.However,it is still necessary to strengthen the prevention and control of PTB in key groups such as men,young adults,farmers and domestic work or unemployed population,and in central urban areas in the future.
