Objective To analyze the registration level of pulmonary tuberculosis complicated with diabetes mellitus (PTB-DM) in Heilongjiang province from 2017 to 2021, and provide scientific evidence for the development of corresponding prevention and treatment strategies.
Methods The data of PTB-DM patients in Heilongjiang between 2017 and 2021 were collected from the Tuberculosis Information Management System. Descriptive epidemiological method was used to analyze the demographic characteristics of the patients, source of the patients, classification of treatment, etiological diagnosis and drug susceptibility testing results. Joint point regression model was applied to analyze the trend of the annual registration rate of PTB-DM in Heilongjiang and its 13 prefectures.
Results A total of 5 816 PTB-DM were registered in Heilongjiang from 2017 to 2021, with average annual registration rate of 3.31/100 000. The annual registration rate increased from 2.22/100 000 to 4.65/100 000 during this period, showing an upward trend of annual percentage change (APC) (APC=17.01%, 95%CI: 4.45%–31.08%, t=4.401, P=0.022). Among the 13 prefectures, the registration rate showed an upward trend in Harbin (APC=23.85%, 95%CI: 18.83%–29.14%, t=16.387, P<0.01), showed a downward trend in Yichun (APC=−81.04%, 95%CI: −94.19%–−37.24%, t=−4.428, P=0.021), while there were no significant difference in the change of the annual registration rate among other prefectures (P>0.05). Of 5 816 PTB-DM patients, 78.30% were males (4 554/5 816), 31.26% were in age group 45–54 years (1 818/5 816), and 55.26% were the jobless or unemployed (3 214/5 816). Of the PTB-DM patients, 76.29% sought medical care directly (4 437/5 816), 80.16% (4 662/5 816) had initial treatment, 67.30% were etiological positive (3 914/5 816), 43.31% showed sensitive drug susceptibility testing results (2 519/5 816).
Conclusion The registration rate of PTB-DM was in increase in Heilongjiang, but area specific differences were observed. Attention should be paid to the prevention and treatment of PTB-DM.
