Are TV, Movies to Blame for Childhood Obesity Epidemic?
By Jane St. Clair
Two new studies found that children who watch television and movies are exposed to ads and promotions for junk food and sugary sodas. This in turn may contribute to the childhood obesity epidemic.
The first study came from the University of California School of Public Health in Los Angeles.
- Frederick Zimmerman and Janice Bell had caretakers keep diaries of which programs 3563 children watched on television.
- Problems with obesity and being overweight were associated with watching television shows that have commercials for junk foods.
- The UCLA study did not find such a correlation when children watched educational television programs or DVDs without commercials.
- The authors said that by the time children are five years old, they have seen more than 4,000 television commercials a year for food. Saturday morning cartoon shows offer one food ad every five minutes, and the majority of the ads are for junk food.
"Commercial television pushes children to eat a large quantity of foods they should consume least: sugary cereals, snacks, fast food and soda pop," Dr. Zimmerman wrote in the American Journal of Public Health.
The second study was from Dartmouth Medical School where researchers found that movies for children feature food product placements.
- Six companies purchase 45% of these placements: PepsiCo, Coca-Cola, Nestle USA, McDonald's, Dr Pepper/Snapple Group, and Burger King.
- While television ads tend to show ads for cereals and snacks, one in four movie placements involves sugar sweetened soda.
"Food placement in movies is one of many factors (contributing to childhood obesity)," lead author Dr. Lisa Sutherland wrote in the journal Pediatrics, "but it is one that may be far more influential than previously realized and perhaps the least well understood."
