At present, few studies have explored the mediating effect of e-Health literacy and self-efficacy on prevention cognition and healthy lifestyle behaviors during the normalization stage of COVID-19 prevention and control. This study aimed to determine the associations among COVID-19-related prevention cognition, self-efficacy, e-Health literacy, and healthy lifestyle behaviors at university students.
By using a stratified cluster random sampling method, 971 students from five universities were recruited between May and August 2021 in Guangzhou, China. We collected participants' demographic characteristics, and assessed self-efficacy, COVID-19-related prevention cognition, e-Health literacy, and healthy lifestyle behaviors. A structural equation model was used for mediation analysis.
The overall mean value of healthy lifestyle behaviors of college students was 0.307 (SD 0.389). Between COVID-19-related prevention cognition, e-Health literacy, self-efficacy, and healthy lifestyle behaviors (r = 0.132-0.505, P < 0.01) were a significant positive correlation. The COVID-19-related prevention cognition had a direct and positive predictive effect on healthy lifestyle behaviors, with a direct effect value of 0.136. e-Health literacy and self-efficacy played both an independent mediating and serial-multiple mediating roles in the association between COVID-19-related prevention cognition and healthy lifestyle behaviors, and the indirect effect values were 0.043, 0.020 and 0.035, respectively.
The results showed that the emphasis on improving college students' prevention cognition, supplemented by improving e-Health literacy and self-efficacy, could improve college students' healthy lifestyle behaviors.
This study was a cross-sectional investigation with no causal relationship between variables.
目前，很少有研究探讨电子健康素养和自我效能在新冠防控常态化阶段对预防认知和健康生活方式行为的中介作用。本研究旨在确定大学生新冠相关预防认知、自我效能、电子健康素养和健康生活方式行为之间的关联。
采用分层整群随机抽样方法，于 2021 年 5 月至 8 月在广州市的五所大学招募了 971 名学生。我们收集了参与者的人口统计学特征，并评估了自我效能、新冠相关预防认知、电子健康素养和健康生活方式行为。采用结构方程模型进行中介分析。
大学生健康生活方式行为的总体平均值为 0.307（SD 0.389）。新冠相关预防认知、电子健康素养、自我效能和健康生活方式行为之间存在显著的正相关关系（r=0.132-0.505，P<0.01）。新冠相关预防认知对健康生活方式行为具有直接且正向的预测作用，直接效应值为 0.136。电子健康素养和自我效能在新冠相关预防认知与健康生活方式行为之间均发挥了独立中介和序列多重中介作用，间接效应值分别为 0.043、0.020 和 0.035。
研究结果表明，重视提高大学生的预防认知，并辅以提高电子健康素养和自我效能，可能会改善大学生的健康生活方式行为。
本研究为横断面调查，变量之间无因果关系。
