Many parents are concerned that exposure to television and computers is affecting their children's health, particularly weight gain. This is especially true given the dramatic rise in overweight children over the last few decades. The percentage of overweight preschoolers has more than doubled since the 1970s.3 In a 2003 study, 26% of children this age were overweight or at risk of becoming overweight. 4 The Centers for Disease Control and Prevention (CDC) classifies children as overweight if their body mass index (BMI) is above the 95th percentile, and at risk of being overweight if they are between the 85th and 95th percentiles.5 An overweight child is four times more likely than a normal weight child to become an overweight adult.6 The trend of children becoming overweight is a serious health concern, as children who are overweight are at greater risk for health problems such as asthma, respiratory ailments, sleep apnea, type 2 diabetes, high blood pressure, orthopedic problems, and depression.7 Given the central role of media in American life and its possible role in childhood weight problems, parents should be aware of how television and computers can impact the health and weight status of young children. Support an active lifestyle for your children.

Given the central role of media in American life and its possible role in childhood weight problems, parents should be aware of how television and computers can impact the health and weight status of young children. To foster the healthy physical development of their children, some key questions for parents to consider include the following, which are addressed in this paper: Does the amount of time that children spend watching television and using computers contribute to children being overweight? Does watching television displace other physical activities in which children might engage? How does the television content that children watch, particularly advertising, affect their eating behaviors and weight status? Do children tend to eat unhealthy foods while they are watching television or using the computer? How can parents help maintain healthy weight in young children? Does the amount of time that children spend watching television and using computers contribute to children being overweight? Research points to media exposure as a key factor among the unhealthy habits that contribute to overweight.8 Young children under six years of age average 2 hours and 24 minutes of daily exposure to media content.9 In the case of young children, media typically involves the television, though it could include videos/DVDs, audio, games, and computers. Watching more than two hours a day of television and/or videos/DVDs is associated with being overweight or at risk of becoming overweight,10 which supports the American Academy of Pediatrics (AAP) guideline of no more than two hours per day of screen time for children over two years of age (and no screen time for younger children). Reducing television use can have a positive impact on children's weight.11 Unfortunately, almost 36% of preschool children exceed the AAP guideline.12 Further, high video game usage, which is more common in higher economic status households, is related to overweight.13 Computer use is also related to higher levels of body fat in children.14 In sum, the answer is yeschildren who watch more television, play more video games, and spend more time on the computer are more likely to be overweight. This leads to the key question: what is it about higher screen time that contributes to children being overweight? "If it weren't for the fact that the TV set and the refrigerator are so far apart, some of us wouldn't get any exercise at all." ~Joey Adams Does watching television and using computers displace other physical activities in which children might engage that would contribute to good health? It is logical to think that children who watch more television and spend more time on the computer are getting less physical exercise, contributing to them being overweight. However, research is finding evidence that TV time does not cause less physical activity. That is, children who watch more television do not necessarily get less exercise than children who watch less television. Reducing TV time does not mean that the kids will go outside and play. While less physical activity definitely contributes to children being more overweight, children who watch more TV are not necessarily less physically active than other children.15 However, the combined effect of not getting adequate active play and spending over two hours a day watching a screen does increase the risk for being overweight.16 But what if children spend the same amount of time doing other sedentary activities, such as reading or craftswould it have the same impact as watching TV? The answer here is no. Research finds that the

PAGE 3

In addition, children are more likely to consume extra calories while watching TV, which is not true of most other hobbies such as reading or crafts.18 In fact, children who read more tend to eat a healthier diet and get more physical activity than children who read less.19 How does the television content that children watch, particularly advertising, affect their eating behaviors and health? We just discovered that time in front of the TV does not necessarily displace physical activity, suggesting that the advertising and marketing of unhealthy foods to children may be a larger contributor to the weight-gain crisis.20 A typical child sees about 40,000 advertisements per year on television, consisting mostly of ads for candy, cereal, soft drinks, and fast foods. During 27.5 hours of Saturday morning programming in May 2005, just over 4 hours were devoted to advertisements, of which 49% of the advertisements were for food, and 91% of these were for foods or beverages high in fat, sodium, or added sugars, or low in nutrients. Despite this nutritional breakdown, 42% of the food advertisements contained a health or nutrition message and 100% had an implicit physical activity message, either or both of which can be misleading at any age!21 Also, note that food manufacturers devote approximately 75% of their advertising budgets to television.22 Children often develop a preference for these advertised products and make purchase requests,23creating conflicts when their parents deny these purchases.24 Advertisements are not restricted to TV, as they also appear on Web sites. The barrage of advertising of unhealthy snack foods to children makes it challenging for them to request healthy foods or even choose not to snack during a commercial break. It appears that advertising to children is a major reason for their weight gain. Do children tend to eat foods of minimal nutritional value while they are watching television or using the computer? Research does support the idea that children eat less healthy food while watching television or using the computer. One of the ways families contribute to excessive viewing time is by allowing children to eat in front of the TV. Parents play a critical role in establishing young children's behaviors, habits, and attitudes about eating and use of media through modeling and determining their physical and social environments. Approximately one-third of families with children under six years of age eat dinner with the TV on. Families who eat while watching TV tend to eat fewer healthy foods, particularly fruits and vegetables, and more foods of minimal nutritional value, such as chips, candy, and soft drinks. Further, this study concludes that "having dinner as a family does not overcome the adverse effects of having the television on during mealtime."25 On the other hand, eating as a family with the TV off is associated with more fruits and vegetables, fewer fried foods and soft drinks, less fat, and more micronutrients.26 In general, high TV/video and computer use is associated with consuming an unhealthy diet. In particular, high TV/video use is associated with consuming more soft drinks, fried foods, and snacks per day, and consuming fewer fruits and vegetables. There are gender differences with the computer. Girls who use the computer more eat more fruits and vegetables; boys do not. However, computer use is also associated with more daily servings of soft drinks and snacks for boys, and soft drinks, fried food, and snacks for girls.27 Another study found that when presented with the opportunity to eat in front of a television, children who watch a lot of television are more likely to eat more food compared to children who do not watch as much television.28 Children who eat while watching television are more likely to eat unhealthy foods and eat higher quantities of food, with mixed results regarding the computer.
