More intersections mean less outdoor activity for children

12.10.2011
High intersection density and well-connected streets in towns and cities may discourage children from being active and exercising outdoors, according to a Queen's University study.

"We've known for a while that high street connectivity—well-connected streets and a high density of intersections in a given area—helps adults stay physically active since it makes it easier and more efficient for them to walk to work or a local store," says Graham Mecredy, the lead researcher and a graduate student in the Department of Community Health and Epidemiology. "However, our findings suggest that high street connectivity has the opposite effect on children's physical activity."

By mapping physical activity results from the 2006 Canadian Health Behaviour in School-aged Children Survey (HBSC) onto street data provided by a geographical information system, the team found that youth aged 11 to 16 years who live in neighbourhoods with streets that are well connected tend to have lower physical activity levels than youth who live in neighbourhoods with streets that are modestly or poorly connected.

"Playing street hockey is an example of how street connectivity and density can influence the physical activity of youth," says Mr. Mecredy. "When traffic increases, or when you don't have access to a quiet cul-de-sac, the game and the associated physical activity may both disappear."

A follow-up study by the same team indicates that while low street connectivity increases children's activity levels, it also results in an increase in minor physical injuries related to bicycle mishaps. The researchers believe that safety initiatives for bicycle use and street designs that encourage bicycle and car separation can help mitigate these incidents.

The team hopes that the findings from both studies will help inform urban and public health policies to improve physical activity among Canadian children.

Other Queen's researchers involved in the studies are Ian Janssen (School of Kinesiology and Health Studies) and William Picket (Community Health and Epidemiology). The results were recently published in the International Journal of Environmental Research and Public Health and Injury Prevention.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
