'Eatin' (not so) good in the neighborhood'

People who don't own a car and live near fast food at greater risk for obesity

Living without a car in close proximity to fast food restaurants is associated with excess body mass index and weight gain, according to a University of Pittsburgh study available online and published in the September issue of the Journal of Urban Health.

Indeed, adults in areas with high fast food concentration who didn't have a car were as much as 12 pounds heavier than those who lived in neighborhoods that lacked such restaurants.

"Owning a car is generally associated with a more sedentary lifestyle and excess weight gain because people spend more time in their cars and less time walking," said Sanae Inagami, M.D., study lead author and assistant professor, University of Pittsburgh School of Medicine. Yet, when Inagami and her colleagues looked at whether a high concentration of fast food restaurants impacted this association, they found that not owning a car in areas where fast food was more readily available increased the risk of obesity.

"Fast food may be specific to weight gain in particular populations and locations," she said. "People who are less affluent don't own cars and can't go distances for healthier foods. As a result, they may end up opting for the lower-priced and high caloric foods available at fast food chains."

The study, part of the Los Angeles Family and Neighborhood Study, was based on a survey of 2,156 adults in 63 neighborhoods in Los Angeles County. Car owners on average weighed 8.5 pounds more than non-car owners except in areas with high fast food concentration, meaning five fast food restaurants per mile. Non-car owners in high fast food concentration areas were found to weigh 2.7 pounds more than car owners who lived in the same areas, and 12 pounds more than residents of areas without fast food outlets. Those who did not own a car and lived in areas without fast food outlets weighed the least.

"There has been a major focus on fast food and its impact on individual health, but we need to consider the availability of all types of restaurants at individual and community levels," said Inagami. "Since our study showed that total restaurant density was associated with weight gain in all individuals, not just those who did not own cars, we also need to encourage people to pay more attention to their food environment," she said.

The study was funded by the U.S. Department of Health and Human Services.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
