Exploratory Study Shows High BMI Linked to Proximity to Convenience Stores

05.07.2010
Research finds strong relationship between food environment, built environment and obesity

Researchers at the University at Buffalo conducting a neighborhood-scaled exploratory study that tested the association between the food environment, the built environment and women's body mass index (BMI) have found that women with homes closer to a supermarket, relative to a convenience store, had lower BMIs, and that the greater the number of restaurants within a five minute walk of a woman's home, the higher her BMI.

The study, "Food Environment, Built Environment and Women's BMI: Evidence from Erie County, New York," involved 172 participants and was published in the April issue of the Journal of Planning Education and Research. It was led by Samina Raja, PhD, UB professor of urban and regional planning.

The study team comprised several UB researchers: Li Yin, PhD, assistant professor of urban and regional planning; James Roemmich, PhD, associate professor of pediatrics; Leonard Epstein, PhD, professor of pediatrics; Changxing Ma, PhD, assistant professor of biostatistics; and graduate students Pavan Yadav and Alex Brian Ticoalu.

"In particular, three findings are significant," says Raja.

"First, a greater number of restaurants within a five-minute walk of a subject's house was associated with a greater BMI, holding other factors constant," she says.

"Second," she says, "on average, women who live within relative proximity to supermarkets and grocery stores (as opposed to convenience stores) tend to have lower BMIs.

"Third, and perhaps most important," Raja says, "the interaction of the food environment and the built environment in a neighborhood carries significant consequences for obesity. For example, a diverse land-use mix, while beneficial for promoting physical activity, is tied to a net increase in BMI when that land is dominated by restaurants."

She says future research on the built environment and health must take into account the role of the food environment on women's health, and the study offers suggestions for how food environments may be improved using planning strategies.

Raja is a nationally regarded community-based scholar in the fields of food security planning and community health whose work supports and is supported by UB's Civic Engagement and Public Policy research initiative.

She points out that more than one-third of U.S. adults were reported to be obese in 2006, with the prevalence of obesity slightly greater among women than men.

"The prevalence of obesity is a significant public health concern because it places indi¬viduals at a risk for a variety of diseases," she says, "and the role of environmental factors in contributing to obesity has received a lot of attention. We have attempted here to explain the paradox of high BMI rates among women living in highly walkable inner city neighborhoods.

Raja says the study has several limitations, among them, the fact that the researchers did not know where their subjects shopped for food, only what outlets were closest geographically. The also were not able to classify restaurants based on their quality -- fast-food and sit-down restaurants were treated as a single category, even though they know that quality varies widely across different types of restaurants.

"The study raises several questions to be addressed in future research," she says, "and suggests that innovative research designs will be necessary to develop greater evidence of causality -- perhaps longitudinal studies that look at how moving one's residence (thus changing exposure to a particular food, food type or built environment) affects physical activity, eating behavior and health outcomes."

The study identifies planning strategies and tools available to improve community food and built environments to support healthy eating behavior.

"Comprehensive plans, regulatory mechanisms and financial incentives can be used individually or in concert to improve food environments," the study says, and cites recent efforts in Madison and Dane County, Wis.; Marin County, Calif.; Harrison County, Miss.; special regulations adopted in New York City that offer zoning incentives (e.g. allowing denser development and reduction in parking requirements) for development projects that dedicate a greater store floor area to fresh foods in underserved neighborhoods; and Pennsylvania's Fresh Food Financing Initiative

The University at Buffalo is a premier research-intensive public university, a flagship institution in the State University of New York system and its largest and most comprehensive campus. UB's more than 28,000 students pursue their academic interests through more than 300 undergraduate, graduate and professional degree programs. Founded in 1846, the University at Buffalo is a member of the Association of American Universities.

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
