Does TV and internet advertising feed children’s junk food habits?

Does TV and internet advertising feed children’s junk food habits?
“Every hour kids spend online increases chance of buying junk food by a fifth,” reports The Daily Telegraph.

A Cancer Research UK survey of almost 2,500 children found those who used the internet or watched commercial television for more than half an hour a day were more likely to ask for, buy or eat junk food (food high in fat, salt and sugar).

Researchers found the primary school-age children surveyed spent an average of 16 hours a week on the internet.

They found 4 of the 5 most popular websites the children used were commercial sites that display online advertising.

That compares to an average of 22 hours of television a week, 12 hours of which was on commercial channels that show adverts.

There are currently no UK guidelines on screen time for children. These are expected in 2019.

What did the study find?

Researchers found links between the amount of time children spent watching TV or on the internet and their likelihood of being overweight, asking for junk food, and buying and eating certain types of junk food.

Time spent watching commercial TV or online wasn’t linked to children’s activity levels.

Each additional hour children spent watching commercial TV was linked to:

  • a 22% increased chance of children asking for food they’d seen advertised
  • a 21% increased chance of children buying food they’d seen advertised
  • a 23% increased chance of them consuming sugary drinks
  • an 18% increased chance of consuming pastries
  • a 16% increased chance of consuming crisps and sweets

Each additional hour children spent online was linked to:

  • a 19% increased chance of children asking for food they’d seen advertised
  • a 19% increased chance of children buying food they’d seen advertised
  • a 9% increased chance of them consuming sugary drinks
  • a 13% increased chance of them consuming pastries and sweet biscuits
  • a 12% increased chance of consuming sweets

Children who watched more than 3 hours of commercial TV a day were 59% more likely to be overweight or obese than children who watched half an hour a day or less.

Those who used the internet more than 3 hours a day were 79% more likely to be overweight or obese than children who used the internet half an hour a day or less.

What does this mean for you?

The study results suggest that watching commercial TV or using internet sites with advertising may be linked to children’s desire for high-sugar, high-fat and high-salt foods they see advertised.

Cancer Research UK has called for the government to ban junk food advertising altogether on TV before 9pm and bring in similar protection for children exposed to advertising online.

Parents wanting to avoid “pester power” might want to think about restricting the amount of time their children spend online, as well as watching commercial TV.

But it’s important to note that we don’t know whether these results mean TV or internet use directly causes obesity or increased junk food consumption.

Obesity and diet are complicated, and many different factors are likely to be involved. For example, parents have a big influence on children’s diets, as well as on how much TV and internet use they’re allowed.
