AB  - Healthy eating is crucial for optimal growth, development, and the prevention of 
      chronic diseases in adolescents. Our study aimed to develop a comprehensive 
      structural equation model (SEM) to analyze the relationships between knowledge, 
      attitudes, practices (KAP), and healthy eating among adolescents in Chongqing. An 
      online questionnaire was administered to middle school students in 39 districts 
      and counties of Chongqing, China from 2 December to 15 December 2021 to collect 
      sociodemographic and KAP information. SEM models were constructed to examine the 
      relationships between educational environment and healthy eating knowledge, 
      attitudes, and practices. The Monte Carlo test was employed to assess the 
      significance of the mediating effect of relevant variables. The study included 
      139,832 adolescents aged 14.8 +/- 0.7 years, with a 14% rate of overweight and 
      obesity. Health and nutrition knowledge averaged a score of 3.60 +/- 1.50 (correct 
      rate: 60%). Participants had positive attitudes (average score: 13.61 +/- 2.29) and 
      engaged in healthy eating practices (average score: 12.06 +/- 3.08). The results of 
      the SEM revealed a significant influence of the educational environment on 
      adolescents' knowledge (beta = 0.235, p < 0.001) and attitude towards healthy eating 
      (beta = 0.143, p < 0.001). Knowledge exhibited positive effects on both attitude (beta 
      = 0.225, p < 0.001) and practice (beta = 0.054, p < 0.001), while attitude exhibited 
      positive effects on practice behavior (beta = 0.565, p < 0.001). The indirect effect 
      of knowledge on practices through attitude was more substantial than the direct 
      effect (ratio 2.361). Our study highlights the mediating role of attitude between 
      healthy eating knowledge and practices. A significant association exists between 
      a favorable educational environment and improved knowledge and positive attitudes 
      toward healthy eating among adolescents. In the future, nutrition and health 
      education should prioritize exploring effective ways to translate knowledge into 
      practices.
