Youths' screen time is constantly increasing. And of course, screens continue to multiply: television, 24h specialized channels, cell phones, computers, portable video consoles, etc. It is all the more worrying since they are also exposed to many ads.
Quebec Children [1]:
Montreal Adolescents [2]: average of 30 hours of screen time per week

Obesity rates increase progressively with the number of hours spent in front of television. This suggests the existence of a causal relationship between the two [3]. But why? Is it because of the content that young people are exposed to? The sedentary lifestyle associated with television? Or both?
Food for thought:
A study seeking to determine whether television contributed to obesity on account of its content or of the sedentary lifestyle it encouraged found the advertising on television, more than the fact of sitting in front of television, to be associated with obesity [8].
Children are exposed to approximately 40,000 advertising messages each year.
In addition, 75% of these messages originate from the food industry and promote foods that are high in fat, sugar, and salt content [9]. Consequences?

This very interesting documentary, produced by the Media Education Foundation, throws desperately needed light on the practices of a relentless multi-billion dollar marketing machine that now sells kids and their parents all kinds of products. A must see!
