Aydin, D., Feychting, M., et al. (2011). Mobile phone use and brain tumors in children and adolescents: A multicenter case–control study. Journal of the National Cancer Institute. Available Online July 27. 

  • This study found that regular users of mobile phones were not statistically significantly more likely to have been diagnosed with brain tumors compared with nonusers. Children who started to use mobile phones at least 5 years ago were not at increased risk compared with those who had never regularly used mobile phones. The absence of an exposure–response relationship either in terms of the amount of mobile phone use or by localization of the brain tumor argues against a causal association.

Kormas, G., Critselis, E., et al. (2011). Risk factors and psychosocial characteristics of potential problematic and problematic internet use among adolescents: A cross-sectional study. BMC Public Health, 11(1), 595. FULL TEXT

Mazur, E. & Richards, L. (2011). Adolescents' and emerging adults' social networking online: Homophily or diversity? Journal of Applied Developmental Psychology, 32(4), 180-188. 

  • The researchers found that adolescents showed greater age homophily than emerging adults, and females received a greater proportion of MySpace “wall” comments than males from same-gender friends. Possible implications of the slight majority of interactions with similar others are discussed.

Pearson, N., Salmon, J., et al.  (2011).Tracking of children's body-mass index, television viewing and dietary intake over five-years. Prev Med. Article Online July 26. 

  • This study found that BMI, TV viewing and dietary intake patterns are moderate-highly stable throughout childhood and into adolescence. Further research that identifies and targets high risk groups to prevent increased BMI, reduce TV viewing and promote healthy dietary behaviours may be justified.

Rushing, S. C. & Stephens, D. (2011). Use of media technologies by Native American teens and young adults in the Pacific Northwest: Exploring their utility for designing culturally appropriate technology-based health interventions. J Prim Prev. Available Online July 30.

  • The researchers found that technology use was exceptionally common among American Indian and Alaska Native (AI/AN) youth, mirroring or exceeding national rates. High rates of online health information seeking were also reported: Over 75% of AI/AN youth reported searching online for health information. These data are now being used by the Northwest Portland Area Indian Health Board and NW tribes to design culturally-appropriate, technology-based health interventions targeting AI/AN youth.
