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.

Core Research Project on Neighborhood Food Environment in New Orleans (2009-2014)

Core-Research-Project-on-Neighborhood-Food-Environment-in-New-Orleans-2009-2014

The Tulane Prevention Research Center’s core research project (2009-2014 grant cycle) examines the food environment in New Orleans, seeking to document changes since Hurricane Katrina, how these changes affect access to healthy food, and the impacts of these changes on food consumption behavior. The core research is community-based and relies on specific interventions and natural experiments to study the changing food landscape in New Orleans and its impacts on residents.

Past Projects

Phone Survey
This project examines the effects of new food stores in New Orleans. New food stores are expected because of the recently approved Fresh Food Retailer Incentive program, which allocates approximately $14 million in forgivable and low-interest loans for expanding fresh food offerings in existing stores or for installing new grocery stores in underserved areas. In the summer of 2011, household surveys were administered via telephone to collect information on shopping habits, food preferences, food consumption, and demographic characteristics. That data is currently being analyzed and prepared for reporting. A follow-up round of telephone surveys is currently being conducted (summer 2013) in order to capture consumption changes related to the new or expanded food stores.

Neighborhood Study (Makin’ Groceries)
In addition to the city-wide phone survey, a supplementary project is currently being implemented. This project aims to have a more focused area of interest, revolving around individual new store openings and their surrounding neighborhoods. Door-to-door surveys were conducted in fall 2012 and spring 2013 in specific neighborhoods that will have changes in food access related to the New Orleans Fresh Food Retailer Initiative as well as in neighborhoods that have not had any food access changes. Results will be compared to analyze differences in healthy eating attitudes and practices as a result of new or expanded food store openings in a neighborhood. Additionally, intercept interviews may be conducted on-site as customers are entering or exiting the premises after the new store has opened. To read more about the project, click here.

Childhood Obesity Assessment
The third project of our core research studies the relationship between physical and social environments and obesity-related behaviors in children. We have collected a baseline dataset on elementary schoolchildren in central city New Orleans. Data include observations on children’s weight and height, parental-reported physical activity and dietary behaviors of the children, as well as household-level data including food consumption, demographic characteristics, and socio-economic conditions. GIS data will allow matching of households with neighborhood characteristics on the food and physical activity environments. In observing the evolution of weight status and obesity-related behaviors among these children, we will be examining the role of specific individual, household, and neighborhood-level factors. Understanding the relative importance of these factors can inform subsequent intervention efforts in New Orleans and in other urban areas of the country.

Analyses are being conducted now with the data collected in January 2010. Based on the information obtained from these data, we conducted another assessment in 2012-2013 among the same participants to evaluate any changes in influence on childhood obesity. We are currently recruiting participants for the follow-up round of data collection to be conducted starting in 2012.

Investigator: Kat Theall, PhD, MPH

Food Store Observations / WIC Study
Our fourth project is focused on assessing the impact of WIC Program policy changes on the food store environment in New Orleans. WIC is the Special Supplemental Nutrition Program for Women, Infants, and Children. In 2009, this USDA food assistance program instituted historic changes to participants’ food package benefits by increasing whole grains, low-fat milks, and fruits and vegetables. We collected in-store information from many food stores across the city before and after the 2009 change was implemented.

We are in the process of analyzing data from 2009 and 2010 to see how the change in policy is affecting the retail food store environment in New Orleans. We completed an additional round of in-store surveys providing a second round of follow-up data collection. We have also adapted the assessment instrument to allow this round of data collection to serve as a baseline measure of food store access and access to different categories of food items (i.e. fresh fruits and vegetables) before any changes in the food environment go into affect as a result of the Fresh Food Retailer Initiative (FFRI).

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…
