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: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
