Food Environment Research

The Tulane PRC engages in a number of research projects related to neighborhood food environments in New Orleans. Studies show that people with access to fresh, healthy foods tend to have a healthier diet. In order to combat obesity, we must work to better understand the neighborhood food environment and increase community members’ access to healthy, sustainable food sources.

School Salad Bar Evaluation

School-Salad-Bar-Evaluation

In New Orleans, the United Fresh Foundation provided salad bars to 43 schools through the “Let’s Move! Salad Bars to Schools” program. The Tulane Prevention Research Center has designed an evaluation study, through multiple school levels, to examine the functioning, maintenance, and effectiveness of the salad bars in New Orleans school lunch programs. Specific aims are to: 1) evaluate the impact of salad bars on fresh fruit and vegetable daily intake by students; 2) determine school level characteristics associated with effective salad bar use; 3) examine training, knowledge, attitudes and behaviors of the food service director and staff relative to salad bar use; and 4) disseminate findings to key stakeholders throughout the city and state. We hypothesize that multiple factors at various school levels will influence the use and effectiveness of the salad bar. Data collection for the study began in January 2013. We anticipate that the knowledge gained from this study will contribute to increased salad bar use in New Orleans schools and assure higher levels of use and sustainability, thereby increasing access to fresh fruit and vegetables by New Orleans students. This study is supported by the Centers for Disease Control and Prevention (CDC) through the Tulane Prevention Research Center (PRC) Cooperative Agreement #U48DP001948 and including Special Interest Project #12-063.

Impact of Food Availability on Diet

In 2006, investigators began work on two new projects exploring the effects of the neighborhood environment on food consumption by residents. Neighborhood environments may contribute to the problem of obesity by providing excess availability of calorie-dense snack foods and insufficient availability of low-calorie nutritious foods such as fruits and vegetables. Low-income individuals – who often have difficult access to fresh fruits and vegetables – consume less of these foods and are more likely to be…
