Healthier kids just the click of a remote away

14.11.2006
Looking for a simple way to increase your child's physical activity level? Try turning off the television, says University of Toronto research.

"Because television is so commonplace in our society, we don't realize how much of an impact it has on youth," says co-author Professor Ken Allison of the department of public health sciences and principal investigator in the physical activity research program. "We need to be reminded that it is crucial to turn them off in order to establish healthy and active patterns in childhood and adolescence that will remain with individuals into adulthood."

Television viewing has been long-suspected of whittling away valuable exercise time and U of T researchers have now shown a direct link between the tube and inactivity. In a recent study reported in the Journal of Adolescent Health, researchers tracked the weekly time spent on sedentary activities such as computer usage, video game playing and television viewing and then measured physical inactivity through daily energy expenditures assessed using a questionnaire. The researchers found a statistically significant link between TV viewing and lack of exercise; the more television children watch, the less energy they expend on physical activity.

The study was based on a sample of 7982 Canadian adolescents, ages 12 to19, from the 2000-2001 Canadian Community Health Survey, conducted by Statistics Canada. The survey revealed an alarmingly large portion of Canadian youth were inactive – 50.3 per cent of males and 67.8 per cent of females. Inactivity was defined as energy expenditure less than three kilocalories per kilogram of body weight per day, which is equivalent to approximately 60 minutes of brisk walking.

After controlling for sociodemographic variables, health status and body mass index, television viewing was significantly associated with inactivity for both males and females. For males this relationship was significant for those watching 20 or more hours of TV per week, while for females the relationship was significant with as little as 6 or more hours of TV viewing per week..

"We know that females report greater barriers to physical activity than males, so it may be that they feel they have less latitude in their discretionary time than males," says Allison. For example, he says that female adolescents attach more importance to a lack of time due to schoolwork, other interests, and family activities than males. Also females tend to have more family responsibilities than males, such as helping around the house and child care for young siblings.

While Allison admits breaking the television watching habit might be difficult for many adolescents, he offers some tips for parents looking to increase their kids' physical activity:

- Provide a positive role model for your kids by limiting your own TV viewing time.

- Plan television watching schedule and allow them to pick their favourite shows.

- Limit the use of snack foods while watching TV to once a week.

Allison concludes, "All kids, including my own, like to watch TV. The key here is to control the amount of TV viewing per week. This is crucial in order to promote physical activity and healthy weights among our greatest asset – our children."

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:...

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...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
