Background Effective strategies for prevention of obesity have been elu sive since the recognition of obesity as a major public health issue [1]. Obesity is a result of chronic, quantitative imbalance between energy intake and energy expenditure,
influenced by a combination of genetic, environmental, psychological and social factors. Therefore, a systems per spective is needed to examine effective obesity prevention strategies [2]. In this study, a system dynamics model was developed using the data from the Girls health Enrichment
Figure 1The complete system dynamic body weight model included sugar and fat intake variables (open circles) as well as environmental and behavioral subsystems (green circles).
