Habitat matters: 'Walkable' communities may make elders healthier

14.02.2007
Some of a neighborhood's features -- the length of its blocks, how many grocery stores or restaurants are nearby -- may be more than selling points for real estate agents. A new study suggests such factors may work to beat back obesity in older people by increasing a neighborhood's "walkability."

The findings by University of Washington and Group Health Cooperative researchers involved more than 900 elderly Group Health members living in Seattle and King County. The results could have broad implications for public health and planning officials throughout the United States, where obesity has been called an epidemic and as baby boomers start to retire.

"The area around someone's home is an opportunity to walk if the habitat is right," said Dr. Ethan Berke, lead researcher of the study published in the March issue of the American Journal of Public Health.

Researchers compared the study participants' self-reported walking behavior with geographic information relating to the location of their residences, as well as some 200 directly observable neighborhood attributes, including parks, streets and foot-and-bike trails, land slope and traffic. Researchers concluded that the chief factors contributing to an area's walkability were higher residential density and clusters of destinations such as grocery stores, restaurants and other services.

Seattle's Maple Leaf, Capitol Hill and Ballard neighborhoods were considered more walkable, for example, than parts of Crown Hill, Burien, and other suburban areas where an attractive retail mix was farther from the study participants' residences.

But Berke said it would be a mistake either to embrace or reject entire neighborhoods or cities based on the research, because the focus was always defined by the area immediately around a person's home where they would be expected to walk as opposed to official neighborhood boundaries.

At the time of the study, which took place over a three-year period, Berke was with the UW's department of family medicine. He is now at Dartmouth Medical School.

Dr. Eric Larson, executive director of Group Health's Center for Health Studies and a co-author of the study, said the research shows you "have a higher chance of walking for exercise - from 30 percent to 600 percent in some comparisons - when you live in a more walkable neighborhood."

"And you may also be more likely to find yourself with people who are walking so it can be, or become, a social phenomenon," he added.

Larson called the findings "potentially important at the public health level when looking at the obesity epidemic and the epidemic of inactivity coming down the pike. The results suggest that as a society, we'd be better if we had more of these kinds of (walkable) neighborhoods."

Berke said the data suggest that habitat differences appear to make a difference for both older men and older women, though the effect seems more significant for the former. The study's 936 participants ranged in age from 65 to 97, with a median age of 78. About 63 percent were classified as overweight or obese.

The authors conceded they could not say categorically that increased walking reduces obesity, but also noted that physical activity is believed to be an important factor for health and weight control. Berke called on other researchers to replicate the study elsewhere to see if they reach similar results, or if the Seattle area is unique.

The study was funded by the National Institute on Aging, the Centers for Disease Control and the UW Exploratory Center for Obesity Research. Other UW authors were: Thomas Koepsell, a professor in epidemiology and health services; Anne Vernez Moudon, professor of urban design & planning, and Dick Hoskins, clinical associate professor of epidemiology and bioinformatics, and also an epidemiologist with the Washington state Department of Health.

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“.

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
