Different sources of media, such as televisions, video games, Internet have become a big part on most of children’s daily life. The rising use of media has led to negative influences on the youngest generation for many reasons. First, media use can attribute obesity among children. In fact, this is explained by the fact that this activity leads to a sedentary life. In addition, advertisements targeted to children are especially for low fat foods as cereals, candies and fast foods. This make children ask for and eat more this kind of food which make them obese. Media also increase violence and aggressions among teens especially because of television and video games that make teens interact with the game. The research shows that media can lead to consumerism. Since children are influenced by what they hear and see in the media, they are spending lots of their money buying advertised products. Although, media is an important source of knowledge, legislation should control what is broadcasted through media. ? Media and Its Danger on Teenagers Nowadays, the pervasiveness of media is linked to the variety of media outlets compared to few decades ago. In fact, media depends not only on print media such as magazines and newspapers, but it also depends on electronic media such as radio, television and video games and on Web media which is based on the Internet. This variety in the sources of media and the progress of technology has allowed the explosion and proliferation of the media. In other words, with the huge development of technology in the late fifteen years, media has become a big part of most of people’s lives, especially young people. Teenagers, who spend lots of their time reading magazines, watching television, playing video games, etc., are daily exposed to a big amount of media. However, the predominance of media in the youths’ lives has led to a public concern. In fact, media may have many negative impacts on the younger generation. First of all, media leads to a poor health among children since it affects their weight status. In fact, most youths who spend many hours in front of media, tend to become obese, thus to have health problems. According to Jordan, “increased rates of overweight occurred among all those who watched television more than 2 hours per day. The odds of being overweight were 4.6 times more for youth watching more than 5 hours of television per day compared with those watching a maximum of two.”(2007, p.47) The body mass index (BMI) which reports the body weight and measures the ratio of weight to height is greater for children who watch many hours of TV than those who watch less than 2 hours. (Kaiser Family Foundation, 2004). This link is explained by many factors. First, since their little age, today’s youths spend more time in front of media such as television video games and other types than any other activity. A study showed that “75 per cent of babies, toddlers and preschoolers watch TV on an average of more than an hour per day” (Jordan and Robinson, 2008, p120). The increase in media consumption leads to a sedentary life, because media is replacing other physical activities. A study on families with obese children demonstrated that “significant decreases in percentage of overweight and body fat were associated with decreasing sedentary behaviors such as watching TV or videos, or playing video or computer games” (Kaiser Family Foundation, 2004, p4). Secondly, the metabolic rate during TV watching which is about 13.3 per cent resting energy expenditure is less than the metabolic rate during resting and sleeping. (Jordan, 2007) In addition, consumption of media is linked to an unhealthy consumption of foods that may cause obesity. Snacks, fast foods and sweets which are low-nutrient and high in calories foods dominate advertisements viewed by children. In fact, “the majority of ads targeted for children are for food: primarily candy (32%), cereal (31%) and fast food (9%)” (Kaiser Family Foundation, 2004, p.5). In
