Canadian youth 4th highest in international obesity study

21.04.2005


Sedentary behaviour – not candy – linked with being overweight, says Queen’s researcher



Canadian youth rank fourth-highest on the obesity scale in a new international study of adolescents from 34 countries, says co-author Dr. Ian Janssen, a professor in Queen’s University’s School of Physical & Health Education and Department of Community Health & Epidemiology.

And sedentary behaviour – like watching television – was strongly correlated with being overweight, he adds.


Along with this alarming finding is one that runs contrary to what the research team expected. Surprisingly, as consumption of candy and chocolate increased, the likelihood of being overweight decreased.

“This does not mean that eating sweets in large quantities is recommended for young people,” says Dr. Janssen, pointing out that the frequency of candy eating, rather than total amount consumed, was surveyed. While difficult to explain, the dietary results only underline the importance of focusing on physical activity rather than food intake as the primary way to combat overweight and obesity, the researcher emphasizes.

“The adolescent obesity epidemic is a global issue,” concludes the paper, which appears in the May issue of Obesity Reviews, a journal of the International Association for the Study of Obesity. “Increasing physical activity participation and decreasing television viewing should be the focus of strategies aimed at preventing and treating overweight and obesity in youth.”

The study is based on statistics gathered in 2001-2002 by the World Health Organization’s Health Behaviour in School-Aged Children report, which surveyed more than 160,000 young people aged 11, 13, and 15 years in Europe and North America. The Canadian component of the WHO initiative was coordinated by Dr. William Boyce of Queen’s Social Program Evaluation Group (SPEG).

Also on the research team from Queen’s are Drs. Peter Katzmarzyk (Physical & Health Education) and Will Pickett (Community Health & Epidemiology). Other members come from the other participating countries of the Health Behaviour in School-Aged Children survey.

As well as placing fourth overall for obesity (at 4.1 per cent), Canadian youth ranked fifth for “overweight” (19.3 per cent). The three countries with the highest prevalence of obesity were Malta (7.9 per cent), the United States (6.8 per cent), and England (5.1 per cent). The highest prevalence of overweight youth was found in Malta (25.4 per cent), the U.S. (25.1 per cent), and Wales (21.1 per cent).

Noting that no Asian or African countries were included, the study says it is very disturbing that in 77 per cent of the countries examined, at least 10 per cent of youth were overweight, and in 20 per cent of the countries, at least 3 per cent were obese.

“The fact that similar associations were found across countries and cultures demonstrates the robustness of these findings,” says Dr. Janssen. “Physical activity interventions should be a fundamental component of health campaigns aimed at reducing the global obesity epidemic.”

Funding for the study came in part from Health Canada and the Canadian Population Health Initiative (CPHI).

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
