Abstract: Objective To analyze the status quo of health literacy of construction workers and its influencing factors,provide reference for carrying out health education and formulating related health policies. Methods From April to December 2022,the construction workers from 6 districts and counties in Jinan City were selected as research objects by multi-stage stratified random sampling. The data were collected by self-designed questionnaire,and the influencing factors of health literacy were analyzed by binary logistic regression model and fsQCA model. Results The health literacy level of 2 332 construction workers in Jinan City was low,and only 16.9% of respondents had health literacy. The logistic regression showed that labor relations,education level and wage level were the influencing factors of health literacy among construction workers（all P<0.05）. The fsQCA model that showed improving health literacy cannot rely solely on a single factor,but rather on the combined effects of various factors,among which education level,salary level,and working hours played a core role in the path of improving health literacy. Conclusions The health literacy level of construction workers in Jinan City should be further improved,and formal labor relations,health education and reasonable working hours should be provided for construction workers.At the same time,logistic regression and fsQCA model can be used together to fully and profoundly understand the relationship between influencing factors and health literacy,which provides a new way to analyze the influencing factors of health literacy.

Key words: Construction workers, Health literacy, Influencing factors, fsQCA model
