Abstract: Objective To analyze the occupational health literacy levels and influencing factors among five occupational groups in the tertiary industry of Zhongjiang County,including teachers,medical staff,sanitation workers,drivers,and express/takeaway delivery personnel,in order to provide data basis for the country to formulate policies to improve occupational health literacy. Methods Relying on the 2023 national key population occupational health literacy monitoring and intervention program,probability proportionate to size sampling（PPS） method was used to carry out probability sampling proportional to population size. Four schools,five medical and health institutions,one environmental health center,eleven transportation companies,two food delivery companies,and six express delivery companies in the county were randomly selected to conduct personal questionnaire monitoring of their frontline workers. Results A total of 243 teachers,234 medical staff,230 sanitation workers,232 drivers,and 226 express/delivery personnel were surveyed in this survey. The overall occupational health literacy level among the five occupational groups was 41.72%,ranked from high to low as follows：medical staff at 75.21%,teachers at 47.74%,drivers at 33.62%,express/takeaway delivery workers at 29.20%,and sanitation workers at 21.74%. There was a statistically significant differences in the occupational health literacy rates among the five occupational groups（χ²=170.171,P<0.01）. There was a statistically significant difference in the occupational health literacy level of drivers of different ages（P<0.05）. There were statistically significant differences in the occupational health literacy levels of medical staff with different marital statuses and educational level（both P<0.05）. There was a statistically significant difference in the occupational health literacy level of sanitation workers with different educational levels（P<0.05）. There were statistically significant differences in the occupational health literacy levels of express/takeaway delivery personnel with different educational levels and average weekly working hours（both P<0.05）. There were statistically significant differences in the occupational health literacy level of the total population with different gender,age,marital status,educational level,actual average monthly income,and household registration type（all P<0.05）. The results of multivariate logistic regression analysis showed that educational level and actual average monthly income were independent influencing factors affecting the level of occupational health literacy in the general population（all P<0.05）. Conclusion The overall occupational health literacy level among the five occupational groups in Zhongjiang County is low,indicating a higher risk of occupational injuries. Special interventions are needed to enhance the occupational health literacy of workers in the transportation,express/delivery,and environmental health industries.
