Abstract: Objective To analyze the results of occupational health examinations in Tengzhou City in 2023,and provide a basis for the prevention and control of occupational diseases in the city. Methods The occupational health examination case cards of workers who were exposed to occupational hazards in Tengzhou City in 2023 were collected. The occupational health examination results such as suspected occupational diseases,occupational contraindications,and abnormal occupational related indicators of labors were analyzed by SPSS 22.0 software.Pearson χ² test or Fisher's exact probability method was used for inter-group comparison. Results In 2023,a total of 33 348 occupational health examination case cards were collected from workers in Tengzhou City,with a suspected occupational disease detection rate of 0.04% and an occupational contraindication detection rate of 0.12%.There were statistically significant differences in the detection rates of suspected occupational diseases and occupational contraindications among different towns and streets（both P<0.05）.The detection rates of suspected occupational diseases and occupational contraindications among dust labors were the highest（0.07% and 0.22%）,while the detection rates of labors with abnormal occupational correlation test indicators in the noise operation was highest（6.02%）. The detection rates of occupational contraindications and occupational related indicators in male workers were significantly higher than those in females（both P<0.05）. As age and length of service increased,the detection rate of suspected occupational diseases gradually increased（both P<0.05）. The detection of suspected occupational diseases and occupational contraindications was mainly concentrated in the mining and manufacturing industries,accounting for 75.00% and 62.50%,respectively. The highest detection rates of occupational contraindications and occupational related indicators for workers in small and micro enterprises were 0.20% and 7.22%,respectively. Conclusion The focus of occupational disease prevention and control work in Tengzhou City is to take effective control measures against occupational hazardous factors such as dust and noise,and further strengthen the supervision of key populations and enterprises,thereby reducing the occurrence of occupational diseases.
