Families and children are in the midst of a media revolution. Television, Internet access, instant messaging, cell phones, and interactive video games are delivering more information for more hours than ever in history. Exposure is occurring at younger and younger ages, often without parental oversight or interpretation. The impact on children is just beginning to be studied. Does media exposure prepare children for the world in which they live or deprive them of critical developmental opportunities? Does the steady display of violence contribute to violent behavior? This article presents a developmental context, discusses the research conducted to date, reviews the recommendations of major organizations, and tries to take a balanced perspective in the midst of a rising tide of media, technology; commercialism, and controversy.

Objective To conduct a population-based survey of television and other media usage in young children to determine (1) total media usage; (2) the proportion of children who have televisions in their bedrooms and who eat breakfast or dinner in front of the television; and (3) predictors of parental concern about the amount of television their child watches. Study design Telephone survey administered to 1454 parents of children <11 years old derived from a diverse clinic population. Results The mean age of the index child was 5.05 years. Mean daily reported child media use was as follows: television (1.45 hours; SD, 1.5); videos (1.1 hours; SD, 1.30); and computer games (0.54 hours; SD, 0.96). Thirty percent of parents reported that their child ate breakfast or dinner in front of the television in the past week, and 22% were concerned about the amount of television that their child watched. In multivariate linear regression, eating breakfast or dinner in front of the television in the past week was associated with increased hours of television viewing (0.38 hours [0.21, 0.54]) and video (0.19 hours [0.04, 0.34]). Having a television in a child's bedroom was associated with increased hours of television (0.25 hours [0.07, 0.43]), video viewing (0.31 hours [0.16, 0.47]), and computer games (0.21 hours [0.10, 0.32]). In general, higher parental education was associated with decreased hours of television and video but not computer games. Older children were 2 to 3 times more likely than younger children to have a television in their bedroom and to have eaten a meal in front of it in the past week. More educated parents were less likely to report that their child had a television in their bedroom and more likely to be concerned about the amount of television their child viewed. Conclusions Combined video and computer game usage exceeded television usage. Both children of low- and high-income parents are at risk for certain behaviors associated with television usage. Parents whose children watched more television were more likely to be concerned about the amount of television their child viewed.

Objective. Cross-sectional studies have suggested that children who were less physically active and children who watched more television (TV) had more excess body weight, but no large nationwide longitudinal studies have addressed whether children who change their personal levels of activity or inactivity, from one year to the next, experience changes in adiposity. Our objective is to study the association between change in body mass index (BMI) over 1 year and same year change in recreational physical activity and change in recreational inactivity (TV/videos/video games). Design. Cohort study using data from 2 mailed questionnaires, 1 year apart. Participants. A total of 11 887 boys and girls, aged 10 to 15, who returned questionnaires in both 1997 and 1998 as part of the Growing Up Today Study. Outcome Measure. Change in BMI from 1997-1998, accounting for increases in BMI associated with growth and development. Results. An increase in physical activity from 1997 1998 was associated with decreasing relative BMI in girls (-0.06 kg/m(2) per hour increase in daily activity; 95% confidence interval : -0.11, -0.01) and in overweight boys (-0.22 kg/m(2); CI: -0.33, -0.10). An increase in inactivity was associated with increasing BMI in girls (-0.05 kg/m(2) per hour increase in daily TV/videos/video games; CI: +0.02, +0.08). Effects were generally stronger among overweight children. Increasing time doing aerobics/dancing and walking were associated with BMI declines for some groups of children. Conclusions. Many children may benefit by increasing their physical activity and by reducing time watching TV or videos and playing video games. In particular, 2 activities accessible to most children, aerobics/dancing and walking, also appeared beneficial.
