This initiative aims to understand the complex interplay of genes and environment (behavioral or lifestyle factors) as one approach to understanding the etiology of obesity. Specific behaviors of interest include nutrition (e.g. macronutrient intake, eating behaviors) and physical activity (e.g. individual response to exercise). In the context of the etiology of obesity, an environmental challenge includes those behaviors or lifestyle factors that have a bearing on energy intake or energy expenditure. Understanding gene-environment relationships is important to developing more efficacious intervention and prevention programs to decrease obesity rates in the US.
Gene-Environment Interplay in Common Complex Diseases: Forging an Integrative Model Workshop
In January 2010, members of HBRB participated in the Gene-Environment Interplay in Common Complex Diseases: Forging an Integrative Model Workshop to discuss and conceptualize a truly trans–disciplinary model of gene–environment research that fully integrates the "genetics" and "environment" sides of the gene–environment equation. The workshop featured presentations to showcase the state–of–the–science and focused discussions to articulate future needs and directions in research and training on gene-environment interplay related to health.
