Check out recently published studies on children, media, and health which explore a range of topics:

Boyland, E. J., Harrold, J. A., et al. (2011). Food commercials increase preference for energy-dense foods, particularly in children who watch more television. Pediatrics. Available online June 27. 

  • This study found that exposure to television food commercials enhanced high television viewers' preferences for branded foods and increased reported preferences for all food items (branded and nonbranded) relative to the low television viewers. This is the first study to demonstrate that children with greater previous exposure to commercials (high television viewers) seemed to be more responsive to food promotion messages than children with lower previous advertising exposure.

Denniston, M. M., Swahn, M. H., et al. (2011). Associations between electronic media use and involvement in violence, acohol and drug use among United States high school students. West J Emerg Med, 12(3): 310-315.  FULL TEXT

  • The researchers found a number of risk behaviors, including involvement in physical fights and initiation of alcohol use before age 13, were significantly associated with frequent TV use or frequent computer/video game use, even after controlling for sex, race/ethnicity and grade.

Garrison, M. M., Liekweg, K. et al. (2011). Media use and child sleep: The impact of content, timing, and environment. Pediatrics. Available online July 1. 

  • The study authors found that violent content and evening media use were associated with increased sleep problems. However, no such effects were observed with nonviolent daytime media use.

Hebden, L. A., King, L. et al. (2011). Advertising of fast food to children on Australian television: The impact of industry self-regulation. Med J Aust, 195(1): 20-24. 

  • This study found that children’s exposure to unhealthy fast-food advertising has not changed following the introduction of self-regulation, and some fast foods advertised for children’s consumption contain excessive energy. The limited impact of self-regulation suggests that governments should define the policy framework for regulating fast-food advertising to children.

Pearson, N. & Biddle, S. J. H. (2011). Sedentary behavior and dietary intake in children, adolescents, and adults: A systematic review. American Journal of Preventive Medicine, 41(2):178-188. 

  • The study authors found that the association drawn mainly from cross-sectional studies is that sedentary behavior, usually assessed as screen time and predominantly TV viewing, is associated with unhealthy dietary behaviors in children, adolescents, and adults. Interventions need to be developed that target reductions in sedentary time to test whether diet also changes.
