We identified six subsystems with their goals: (1) interaction between adolescents and the food environment, with profit maximisation as goal, (2) interaction between adolescents and the physical activity environment, with utility maximisation of outdoor spaces as goal, (3) interaction between adolescents and the online environment, with profit maximisation from technology use as goal, (4) interaction between adolescents, parFrontiers in public health1128316https://www.ebi.ac.uk/biostudies/studies/S-EPMC10248031biostudies-literatureUnderstanding the system dynamics of obesity-related behaviours in 10- to 14-year-old adolescents in Amsterdam from a multi-actor perspective.PMC10248031Luna Pinzon Avan den Eynde EKremers SPJChinapaw MJMRenders CMHermans RStronks KEmke HAltenburg TWaterlander WDijkstra SCBusch VfalseUnderstanding the system dynamics of obesity-related behaviours in 10- to 14-year-old adolescents in Amsterdam from a multi-actor perspective.<h4>Introduction and methods</h4>To develop an understanding of the dynamics driving obesity-related behaviours in adolescents, we conducted systems-based analysis on a causal loop diagram (CLD) created from a multi-actor perspective, including academic researchers, adolescents and local stakeholders.<h4>Results</h4>The CLD contained 121 factors and 31 feedback loops.
