Abstract: A multi-stage cluster random sampling method was used to conduct a questionnaire survey on 4 088 permanent residents aged 15-69 in 10 administrative districts of Tianjin. Based on the chi square test and multivariate logistic regression model,this paper explores the level of environmental health literacy among residents in Tianjin in 2023 and its influencing factors,and analyzes the impact of demographic characteristics on the level of environmental health literacy. The environmental health literacy level of Tianjin residents is 26.2%,with literacy levels of basic concepts,basic knowledge,basic behaviors,and skills being 28.3%,27.6%,and 35.8%,respectively. Residential area,age,occupation,and education level have a significant impact on environmental health literacy,while there is no significant difference between genders. The literacy level of urban residents and those with higher education levels is significantly higher than that of rural residents and those with lower education levels. It is suggested that different strategies of science popularization and education should be adopted for different groups of people,especially rural and elderly groups.

Key words: environmental health literacy, influencing factors, multivariate logistic regression model
