It’s not the hours of TV viewing, it’s the number of junk food commercials that cause obesity
The association between television viewing and childhood obesity is directly related to children’s exposure to commercials that advertise unhealthy foods, according to a new UCLA School of Public Health study published in the American Journal of Public Health.
The study, conducted by Frederick J. Zimmerman and Janice F. Bell, gathered data from primary caregivers of 3,563 children, ranging from infants to 12–year–olds, in 1997.
Among all children, commercial viewing was significantly associated with higher BMI, although the effect was stronger for children younger than 7 than for those older
Non–commercial viewing, including watching DVDs or educational television programming, had no significant association with obesity. The findings strongly suggest that steering children away from commercial television may be effective in reducing childhood obesity, given that food is the most commonly advertised product on children’s television and the fact that almost 90 percent of children begin watching television regularly before the age of 2.
