Objective To understand the occupational health literacy levels of workers in the electronics industries in a city and their influencing factors, providing a basis for improving the occupational health literacy levels of workers in this industry.

Methods From January to July 2023, a judgment sampling method was used to select workers from 9 electronics industry enterprises as research subjects. The Chinese Workers' Occupational Health Literacy Questionnaire was used to survey the occupational health literacy status, and logistic regression analysis was used to analyze the influencing factors.

Results A total of 480 workers were investigated, and 468 valid questionnaires were collected with an effective recovery rate of 97.50%. The overall occupational health literacy level was 44.87% (210/468), and the four dimensions of occupational health literacy, from high to low, include basic knowledge of occupational health protection (77.35%), healthy work styles and behaviors (47.65%), basic skills of occupational health protection (30.34%), and occupational health law knowledge (26.07%). The results of the multivariate logistic regression analysis showed that the education level, monthly income level, current job tenure, and job type were influencing factors of occupational health literacy levels of workers in the electronics industry. Among them, workers with a college degree or above had higher occupational health literacy levels (OR = 5.128, 95%CI: 1.017 to 25.865) compared to those with primary school education or below; workers with an average monthly income of 5 000 to less than 7 000 yuan had higher occupational health literacy levels (OR = 5.853, 95%CI: 1.104 to 31.032) compared to those with an average monthly income of less than 3 000 yuan; workers with a current job tenure ≤ 1 year had higher occupational health literacy levels (OR = 3.012, 95%CI: 1.093 to 8.298) compared to those with a current job tenure ≥ 10 years; and the managers had higher occupational health literacy levels (OR = 3.070, 95%CI: 1.636 to 5.759) compared to production workers. These differences were all statistically significant (all P < 0.05).

Conclusions The occupational health literacy levels of workers in the electronics industries in this city were lower than the national key population's occupational health literacy levels, especially in the dimension of occupational health law knowledge. Frontline workers, and workers with more than 10 years of current job tenure, low education levels, and low income were the key groups for improving occupational health literacy levels in the electronics industry.
