Work Group III

This article presents conclusions drawn from a work group to examine methodologic issues in research on food and physical environments. Transdisciplinary research on these environments has been hampered by several methodologic challenges. The authors identify several key challenges and provide recommendations for improvement.


  • Improve the conceptual and theoretical models to ground research;
  • Support innovative and experimental thinking;
  • Improve causal-effect estimation, cross-validation techniques, measurement error models, and methodologic research.

Avoiding the methodologic obstacles faced in this field will strengthen its contributions toward research on the intersection of food and activity environments and health.
