In her research, Lorraine Reitzel, Ph.D., uses geographic information systems technology, with the help of Seann Regan, to obtain information about a geographic area. This allows her to better understand why people engage in certain behaviors and how their environment impacts health and cancer risk.

Background GIS-based walkability measures designed to explain active travel fail to capture “playability” and proximity to healthy food. These constructs should be considered when measuring potential child obesogenic environments. Purpose The aim of this study was to describe the development of GIS-based multicomponent physical activity and nutrition environment indicators of child obesogenic environments in the San Diego and Seattle regions. Methods Block group–level...

Background: Healthy diets are supposed to be more environmentally friendly because they rely mainly on plant-based foods, which have lower greenhouse gas emissions (GHGEs) per unit weight than do animal-based foods. Objectives: The objectives were to estimate the GHGEs associated with the consumption of self-selected diets in France and to analyze their relation with the nutritional quality of diets. Design: For each adult in the national dietary Individual and National Survey on Food...
