Advertising to Children

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. 

Screen Time

Quebec Children [1]:

  • 2 hours/weekday
  • 4 hours/weekend day

Montreal Adolescents [2]: average of 30 hours of screen time per week

  • 20 hours of TV time
  • 10 hours of computer time

Association between television and obesity

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:

  • 29% of obesity cases (12-17 years old) could be prevented by cutting the time spent in front of television to one hour or less per week [4].
  • Children who spend more than 2 hours per day in front of television are twice as likely to be overweight and twice as likely to be obese as children who spend 1 hour or less [5].
  • 1 extra hour of television = consumption of 167 additional calories (particularly from high-calorie foods with little nutritional value frequently advertised on television) [6].
  • When playing video games, young adolescents eat more whether they feel hungry or not [7].

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].

Effects of Advertising on Children

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?

Unhealthy Eating Habits
  • The intensity of marketing of foods that have high caloric values and low nutritional values is recognized by the World Health Organization (WHO) as an important factor of the obesity epidemic [10].
  • Television ads influence food choices [11] and encourage consumption [12].
  • Even brief exposure to food advertising would suffice to influence food preferences for preschool aged children [13].
  • Children snack 45% more when exposed to food ads [14].

Preferences and Recognition of Brands
  • A study that appeared in the journal Psychology & Marketing [15] demonstrated that:
    • Children between 3 and 5 years old have the emerging capacity to use advertising to define which products will be most fun and make them popular, even if they do not yet have the ability to read.
    • They associate, from a young age, a brand, its logo, and their potential utility in their daily life.
    • A brand's popularity and the peer pressure the results from it have an impact on demands made by young children.
    • McDonald’s is recognized by 93% of children surveyed for the purpose of the study.

Consumption Attitudes
  • Children's expenses and influence on parents' shopping [16]:
    • Each year, 4 millions Canadian children from 2 to12 years of age spend 1,5 billion dollars of their own pocket money and influence products bought up to 15 billion dollars [17].

Nagging Phenomenon
  • Incessant demands of children to parents and financial stress experienced by them [18]
    • Around age 2, the first real demands to parents about consumer products appear [19].

Devaluation of Authority

In advertising, children are portrayed as autonomous consumers who know everything, unlike the parents who frequent play the 'bad' role [19].

Consuming Kids
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!
