Today's children and adolescents are immersed in both traditional and new forms of digital media. Research on traditional media, such as television, has identifi ed health concerns and negative outcomes that correlate with the duration and content of viewing. Over the past decade, the use of digital media, including interactive and social media, has grown, and research evidence suggests that these newer media offer both benefi ts and risks to the health of children and teenagers. Evidence-based benefi ts identifi ed from the use of digital and social media include early learning, exposure to new ideas and knowledge, increased opportunities for social contact and support, and new opportunities to access health promotion messages and information. Risks of such media include negative health effects on sleep, attention, and learning; a higher incidence of obesity and depression; exposure to inaccurate, inappropriate, or unsafe content and contacts; and compromised privacy and confi dentiality. This technical report reviews the literature regarding these opportunities and risks, framed around clinical questions, for children from birth to adulthood. To promote health and wellness in children and adolescents, it is important to maintain adequate physical activity, healthy nutrition, good sleep hygiene, and a nurturing social environment. A healthy Family Media Use Plan (www. healthychildren. org/ MediaUsePlan) that is individualized for a specifi c child, teenager, or family can identify an appropriate balance between screen time/online time and other activities, set boundaries for accessing content, guide displays of personal information, encourage age-appropriate critical thinking and digital literacy, and support open family communication and implementation of consistent rules about media use.

Early television exposure is associated with attentional problems at age 7. Efforts to limit television viewing in early childhood may be warranted, and additional research is needed.

Television exposure is not independently associated with child language development when adult-child conversations are controlled. Adult-child conversations are robustly associated with healthy language development. Parents should be encouraged not merely to provide language input to their children through reading or storytelling, but also to engage their children in two-sided conversations.

Psychological sequelae are examined in 130 former childhood leukemia patients and 155 comparison participants and their parents. The major dependent variables are symptoms of anxiety and posttraumatic stress, family functioning, and social support. Multivariate analyses of covariance indicated significantly more posttraumatic stress symptoms in mothers and fathers of childhood leukemia survivors (p < .001) and no differences between survivors and peers. There were no significant group differences for family functioning or social support, although they were associated with anxiety and posttraumatic stress outcomes. Current child age, age at diagnosis, and months off treatment were not significantly correlated with outcome. These findings document the long-term impact of childhood cancer treatment on parents. The lack of significant differences for survivors argues for further attention to the relevance of posttraumatic stress disorder for childhood cancer survivors. The clinical implications are that psychological interventions are needed during and after cancer treatment.
