Effective strategies for prevention of obesity have been elusive since the recognition of obesity as a major public health issue . 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 perspective is needed to examine effective obesity prevention strategies . In this study, a system dynamics model was developed using the data from the Girls health Enrichment Multi-site Studies (GEMS). GEMS tested the efficacy of a 2-year family-based intervention to reduce excessive increase in body mass index in 8-10 year old African-American girls.
Results and discussion
The GEMS study was supported by cooperative agreements HL62662 and HL62663 from the National Heart, Lung, and Blood Institute, National Institutes of Health. This work was supported in part by The University of Memphis Bioinformatics Program, The University of Memphis School of Public Health, and the Memphis Research Consortium.
