Barnett, A., Cerin, E. et al. (2011). Active video games for youth: A systematic review. J Phys Act Health, 8(5): 724-737. 

  • The authors found that active video games (AVGs) are capable of generating energy expenditure in youth to attain physical activity guidelines. Few studies have assessed sustainability of AVG play, which appears to diminish after a short period of time for most players. Better-quality future research must address how AVG play could be maintained over longer periods of time.

Chen, J.-L., Weiss, S., et al. (2011). The efficacy of the Web-based childhood obesity prevention program in Chinese American adolescents (Web ABC Study). Journal of Adolescent Health, 49(2): 148-154. 

  • The study authors found that the intervention resulted in significant decreases in waist-to-hip ratio and diastolic blood pressure  and increases in vegetable and fruit intake, level of physical activity, and knowledge about physical activity and nutrition. This Web-based behavior program for Chinese American adolescents and their families seems feasible and effective in the short-term. 

Choi, K., J., Forster,L. et al. (2011). Prevalence of smoking in movies as perceived by teenagers: Longitudinal trends and predictors. American Journal of Preventive Medicine, 41(2): 167-173. 

  • This study found that teenagers' perception of the prevalence of smoking in movies declined over time, which may be attributable to  changes made by the movie industry. Despite the decline, teenagers were still exposed to a moderate amount of smoking imagery.  Interventions that further reduce teenage exposure to smoking in movies may be needed to have an effect on adolescent smoking.

Granich, J., Rosenberg, M. et al. (2011). Individual, social, and physical environment factors associated with electronic media use among children: Sedentary behavior at home. J Phys Act Health, 8(5): 613-625.

  • The researchers found that 87% of participants exceeded electronic media use recommendations of ≤ 2 hrs/day. Efforts to modify children's EM use should focus on a mix of intervention strategies that address patterns and reinforcement of TV viewing, household rules limiting screen time, and the presence of EM devices in the child's bedroom.

Whiteley, L. B., Brown, L. K., et al. (2011). African American adolescents and new media: Associations with HIV/STI risk behavior and psychosocial variables. Ethn Dis, 21(2): 216-222. FULL TEXT.

  • The findings from this study suggests that riskier youth are online and using cell phones frequently. The Internet and cell phones may be useful platforms for targeted health promotion and prevention efforts with African American adolescents.
