Behavior When collecting the literature, of all the areas revolving around childhood obesity behavior is the most widely expressed factor that contributes to childhood obesity. In the literature there are many sub concepts that embody behavior. These sub concepts are physical activity, diet, technology, and sleep. Physical Activity Physical activity is a very important factor in the development of childhood obesity. By not being physically active children put themselves at a higher risk of developing childhood obesity (Roberts, 2000; Steinbeck, 2001). Steinbeck’s work defines physical activity as not being asleep and being inactive (2001). Physical activity is important because it is a means of using energy in the human body. When energy is not being used then the body stores the excess. In obese children it has been noticed that they have lower energy usage than their peers. The biology behind the relation of childhood obesity and the usage of energy involves basal/resting metabolic rate, dietary thermogenesis, and physical activity (Roberts, 2000; Steinbeck, 2001). One must understand the body’s use of energy in order to see the connection to childhood obesity. In terms of basal and resting metabolic rate, basal is the metabolic rate after complete bed rest and resting is the metabolic rate is during the day (Roberts, 2000; Steinbeck, 2001). These rates are the minimal amount of energy that the body uses when at rest but the basal metabolic rate is the most accurate because it is taken in a laboratory (Roberts, 2000). Dietary thermogenesis is energy used in the digestion process. This tends to increase the basal metabolic rate (Roberts, 2000; Steinbeck, 2001). Basal metabolic rate and dietary thermogenesis are the body’s way of using a small amount of energy. The major usage of energy in the human body is physical activity. When children are engaged in physical activity the body uses up significantly more energy than by the basal metabolic rate and dietary thermogenesis. However, the amount of energy used is dependent on how strenuous the activity is. The notion behind physical activity is that children need to use more energy than they acquire. When children eat food then they increase the energy acquired. For a child to be at risk of developing obesity the child must acquire more energy than they use, which would result in gaining weight. When this occurs over an extended period of time children will acquire excessive weight making them obese (Ebbeling, Pawlak, & Ludwig, 2002). A considerably related factor to this is dietary intake.
In combination with bigger portions, children are eating very high calorie and high fat foods at a very early age. The food that children are eating is foods that are not home cooked but are processed goods from supermarkets and from fast food restaurants (Ebbeling, Pawlak, & Ludwig, 2002; Cowley, et al., 2000). There is a relation to what environment a child is exposed to which will be covered later. Some foods that children are eating are “ready-to-eat cereals, potatoes, soft drinks, cakes and biscuits” (Ebbeling, Pawlak, & Ludwig, 2002, p. 476). Along with these unhealthy foods, children are drinking excessive amounts of sugar-sweetened drinks Ebbeling, Pawlak, & Ludwig, 2002; Ludwig, Peterson, & Gortmaker, 2001). These drinks are high in glucose content, which is potential energy for the body. All of these trends in diet are very unhealthy for young children. Children are acquiring much more energy than they are using when they are having such unhealthy diets. When the energy acquired is more than the energy used, the excess energy is stored in the body as fat (Roberts, 2000). Diet is an important factor in a child’s behavior because the amount and choice of foods consumed by a child can greatly determine if obesity is likely in the child’s future.
Television viewing in children has been known to cause obesity. This is because television viewing is one of the major causes of physical inactivity in children in this technological world. Children are watching a significant number of hours of television, which is taking away from time of being physically active. At the same time children are being influenced by the television in eating high fat foods because of advertising of this unhealthy food. (Ebbeling, Pawlak, & Ludwig, 2002; Drohan, 2002; Faith, Berman, Heo, Pietrobelli, Gallagher, Epstein, Eiden, & Allison, 2001; Lowry, Welchsler, Galuska, Fulton, & Kann, 2002). Because of television, video games are another factor in obesity because it too takes away from physical activity. In the home, children use video game consoles that provide entertainment through the use of a small portable computer, that plays the games, and a television set. There has been a movement away from physical activity to television, playing video games and also computers. This means that the usage of energy is decreasing in children’s lives, and with the type of diet that children are having these days, obesity is a likely health challenge to develop (Cowley et al., 2000; Ebbeling, Pawlak, & Ludwig, 2002; Drohan, 2002; Ridley & Olds, 2001). In video game centers children use up a lot of energy due to the fact that the games in video game centers involve a lot of body movement to operate a game. Games that children engage in are games like miniature basketball, shooting, games, simulation driving games, simulation BMX games etc. Some of these games involve vigorous movement in the upper body, lower body, forearms, and hands of children who play them and these games can last up to five minutes per game. Arcade centers seem to have no threat to children in developing obesity however, studies have shown, games that allow children to use up a lot of energy are not used as often as the games that do not use up a lot of a child’s energy in arcade centers (Ridley & Olds, 2001). When activities such as television, video games, and computers take away from other more vigorous children’s activities like outdoor play, obesity is a likely health challenge to arise in the future of affected children.
