Television And Childhood Obesity Essay Outline

Obesity is one of the major health problems among children today. This is evident from the United States and many developed countries in the world. Pediatrics in the past has come up with different ways of addressing the issue for instance by encouraging much time for physical activity in schools. They have also argued that television viewing in children should be reduced to at least two hours per day (Crane et al. 2013). These efforts have borne no fruits since obesity among children still remains to be a big challenge. Studies that have been carried in the past have showed that the major cause of obesity is eating junk food and lack of exercise. However, it has not been answered what really makes children not to have physical exercises like sporting and what makes them consume junk foods yet they have been warned that it will make them overweight. There are attributes that TV viewing is the main reason why children consume junk foods because of the different adverts that they are exposed to (Mitchell, Pate & Liese, 2013). It also denies them the opportunity to have physical exercises. Therefore, it is argued that there is a direct relationship between TV viewing in children and child obesity.

Although researchers have strongly supported TV viewing to be a major cause of obesity in children, there have been no longitudinal studies of childhood viewing and their health. In addition, it has not been explained how TV viewing can contribute to overweight in children yet some argue that it is a psychological activity that makes them active in one way or the other (Kimm, 2003). This study will be aimed at looking at the relationship between television viewing and childhood obesity.

Background and Rationale

Television viewing among children is said to be worse because research has shown that more than 70 percent of them have TV in the bedroom. They are said to spend most of their time watching television when they are not in school. This is more with American children aged 8 to 18 years (Mitchell, Pate & Liese, 2013). Researchers have found that television viewing among children results to increased wait specifically high waist circumference. It is directly related to obesity, however, this is said to happen in two different ways. The first one is the idleness whereby children do not have time for exercise. This results to increased weight. The other side of the matter looks at the adverts in the television. There are many ads on unhealthy or junk food that the children get attracted to an end up getting the foods. This is also contributes to obesity in children.

Since the United States has received alarming increases in childhood obesity, treatments have been developed to help. This has, however, being unsuccessful because the results have been modest. Prevention is the only way childhood obesity can be reduced. Most prevention measures relate to increase in physical activity, two hours of TV viewing in a day, and healthy diets (Crane et al. 2013). It has not been well understood how TV can be a cause of obesity in children because many of the studies that have been carried out in the past have shown lack of physical exercises and unhealthy diets as the major causes of the disease. This calls for the need to find the relationship between television viewing and childhood obesity.

The objectives of this research will be:
1. To find out the relationship between television viewing in children and childhood obesity
2. To find out how TV viewing can result to increased weight in children
3. To find out whether limiting the time children watch TV can help address childhood obesity

Research Hypotheses and/or Research Questions
The study will be directed by the three objectives that have been stated so that it can answer the question:
What is the relationship between television viewing and childhood obesity?

Significance of Study
This study is crucial because it will provide evidence on how TV viewing is resulting to overweight in children. Many parents do not have information on this which makes them not to control the time their children are exposed to TV viewing. Therefore, when they get the information it will be expected that they will take corrective measures to ensure that their children are not exposed to TV viewing for long. They will be made aware of the risks of TV viewing in their children.

The study will also fill a gap on the different ways in which television viewing can result to overweight and childhood obesity. Most of the studies that have been carried out in the past have only showed TV viewing as a sedentary activity that increases the risk of obesity; however, they have failed to show how this happens (Mitchell, Pate & Liese, 2013). The study will therefore, bring in new information in the field to show how TV viewing can contribute to childhood obesity.

Literature Review

Obesity in Children
According to Kimm (2003), childhood obesity is ‘an emerging pandemic of the century’. This has been marked by increase in the number of children with obesity over the last two decades. Over the period childhood obesity has been observed to increase by 50 percent and the number has doubled that of adults with obesity. In the United States it believed that 20-25% of children have obesity. Childhood obesity has become a major public health problem in the United States just like it is many countries in the world. The major problem with the disease is that it affects children in their childhood and later in their adulthood.

Factors Influencing Obesity in Children

Genetic Factors
Mitchell, Pate & Liese (2013) came up with 15 chromosomal loci that were linked to weight, body fat, and other obesity related trains. There were seven genes that they identified as possible causes of obesity in humans. It was also found that obesity results from the interaction of multiple genes and not from a single gene. However, this is not a major cause of obesity in children because it is stimulated by other factors like food intake. On its own genetic factors cannot strongly account for overweight and obesity in children.

Energy Balance
This refers to a situation where there is increased energy intake and decreased energy expenditure. It can simply be explained as lack of exercise and idleness. This is a major cause of childhood obesity because of incidental snacks. Children will eat without plans and in most cases they watch TV while having snacks next to them. Between meals children have been observed to do much snacking (Mitchell, Pate & Liese, 2013). This results to accumulation of fats in the body because they are not doing any exercise which can lower the energy intake. This eventually results to increase in weight and obesity.

Sedentary Behavior
This is the main cause of obesity in children. It is defined through inactivity where children will spend most of their time in sedentary activities. These are activities that do not promote physical activity like browsing, playing games, watching movies and generally TV viewing. In the digital age browsing is a major cause of inactivity in children because they spent most of their in social networks. Some like Facebook and Twitter are very addictive and will end up consuming much time of the children. This results to increased BMI. McLennan (2004) made it clear that substitution of sedentary activities in children is the only way children can be secured from obesity (Mitchell, Pate & Liese, 2013). This is because they will also be prevented from junk eating because during the sedentary activities they engage too much in snacking.

Coakley (2003) identifies the media to be a major cause of obesity in children however this has not been observed by many people. If we look at the ads in the media we will see that majority of them that are related to food advertise junk foods. This is because they are on high demand and each entrepreneur in the business is trying to pursuit for a competitive advantage through advertising (McLunnan, 2003). There are only few adverts that encourage good nutrition. This encourages children to eat these junk foods. It encourages unhealthy lifestyle and as much as children will try to avoid they will be encouraged and tempted by the adverts in the media.

There is evidence that the lifestyle of parents has an impact on childhood obesity. For instance, parents who do not take any exercise are likely to encourage their children not to take any exercise. If parents are consuming too much of junk foods this is likely to be the case with their children. In many cases it has also been observed that parents involve children in their leisure activities like travelling and watching movies which further encourages inactivity in children. The end result of this is overweight and obesity.

TV Viewing in Children
TV watching is the favorite pastime in the United States just like it is in many parts of the world. According to pediatrics children are supposed to view a maximum of two hours per day, but this is not the case because the time spent on TV by many children in the United States is over five hours. The worse is that many of them have TVs in their bedrooms. This makes it hard for parents to limit the time their children are exposed to the TV screen (Mitchell, Pate & Liese, 2013). It has been found out that TV viewing in children accounts a big percentage on their overweight and obesity.
The main reason why children are exposed to long time television is because of the lifestyles that they have been brought up in. in many families there are house helps who are left with the duty of caring for children. They just leave the television to keep the children busy as they perform other household chores. In addition, food is always available and the households will provide the food that the children want.
How TV Viewing Adds to Childhood Obesity
There is widespread speculation that TV watching is one of the most easily modifiable risk factors to obesity among children. American children spend more time playing games and watching television than doing anything else except sleeping (Coakley, 2003). Two primary mechanisms by which television viewing contributes to obesity have been suggested: reduced energy expenditure from displacement of physical activity and increased dietary energy intake, either during viewing or as a result of food advertising.
Researchers have found that TV watching can promote overweight and obesity in children in different ways. One of the main ways is that during TV viewing children are inactive. Since they spent much time watching television, they are idle and inactive. Therefore, they do not make use of the high energy intakes. The result is that the excess energy accumulates in the body making them overweight.
The other way is snacking whereby children have snacks close to them when playing games on their play stations or when watching TV. This increases their energy intake (Coakley, 2003). They also add their meals which further increasing their energy intakes yet they are not exercising.
TV viewing also promotes obesity in children through the different adverts. The adverts are mostly on junk foods because they are on high demand among adults. Consumption of junk foods in the country has been observed to increase by over 50 percent in the last two decades (Mitchell, Pate & Liese, 2013). The adverts encourage children to make purchases of such foods. As much as children will want to keep off from the junk foods, their battle is counteracted by pressure from the media.

Research conducted at Harvard first linked TV watching to obesity more than 25 years ago. (5) Since then, extensive research has confirmed the link between TV viewing and obesity in children and adults, in countries around the world. And there’s good evidence that cutting back on TV time can help with weight control-part of the reason why many organizations recommend that children and teens limit TV/media time to no more than two hours per day. This article briefly outlines the research on how TV viewing and other sedentary activities contribute to obesity risk, and why reducing screen time and sedentary time are important targets for obesity prevention.

TV Viewing and Childhood Obesity

Studies that follow children over long periods of time have consistently found that the more TV children watch, the more likely they are to gain excess weight. (6–10) Children who have TV sets in their bedrooms are also more likely to gain excess weight than children who don’t. (11,12) And there’s evidence that early TV habits may have long-lasting effects: Two studies that followed children from birth found that TV viewing in childhood predicts obesity risk well into adulthood and mid-life. (13,14)

Several trials designed to reduce children’s TV use have found improvements in body mass index (BMI), body fat, and other obesity-related measures. (15–18) Based on this evidence, the U.S. Task Force on Community Preventive Services recommends that communities roll out behavior-change programs aimed at curbing screen time, since there’s “sufficient evidence” that such programs do help reduce screen time and improve weight. (19)

Some of these successful TV-reduction trials have been delivered through the schools: The Planet Health trial, for example, used middle school classroom lessons to encourage less TV viewing, more activity, and improvements in diet; compared to the control group, students assigned to receive the lessons cut back on their TV time, and had lower rates of obesity in girls. (17) Another trial found that third- and fourth-graders who received an 18-lesson “TV turnoff” curriculum cut back on TV time and on meals eaten while watching TV, compared with children in the control group, and they had a relative decrease in BMI and other measures of body fatness. (16) TV “allowance” devices, which restrict TV watching to a set number of hours per week, may help limit children’s screen time, and in turn, help with weight control. (18)

TV Viewing and Adult Obesity

There’s convincing evidence in adults, too, that the more television people watch, the more likely they are to gain weight or become overweight or obese. (20) And there’s emerging evidence that too much TV watching also increases the risk of weight-related chronic diseases. For example, the Nurses’ Health Study followed more than 50,000 middle-age women for six years. For every two hours the women spent watching television each day, they had a 23 percent higher risk of becoming obese and a 14 percent higher risk of developing diabetes. (21) A more recent analysis that summarized the findings of this study and seven similar studies found that for every two hours spent watching TV, the risk of developing diabetes, developing heart disease, and early death increased by 20, 15, and 13 percent, respectively. (3)

TV reduction trials have focused largely on children, not adults. But a small pilot study in 36 men and women suggests that an electronic TV “lock-out” device could help adults with weight control. Half of the volunteers were assigned to use a lock-out device that would cut their TV viewing time by half; the other half were assigned to a control group with no limits on TV. The volunteers who used the lock-out device watched less television and burned more calories each day, and they had a greater reduction in BMI than the control group. The difference in BMI did not reach statistical significance, however. (22) Given the study’s small size, more research is needed to confirm these results.

How Does TV Watching Increase the Risk of Obesity? A Closer Look at Food Marketing

Researchers have hypothesized that TV watching could promote obesity in several ways: displacing time for physical activity; promoting poor diets; giving more opportunities for unhealthy snacking (during TV viewing); and even by interfering with sleep. (23)

Many studies show that TV viewing is associated with greater calorie intake or poorer diet quality, (24–27) and there’s increasing evidence that food and beverage marketing on television may be responsible for the TV-obesity link. The effects of TV viewing on physical activity are much smaller than on diet, so they don’t seem to play as strong a role. Some research findings that support the food marketing-TV-obesity link:

  • The thousands of food-related TV ads that children and youth see each year are primarily for high-calorie, low-nutrient foods and drinks, according to a comprehensive review of the evidence by the Institute of Medicine (IOM). (28) Food marketing influences children’s food preferences and purchase requests, and marketers rely on this “pester power” to influence what parents buy.
  • Branded foods, drinks, and restaurants are often featured in TV shows and movies (the ad industry term for this is “product placement”), and these product placements are overwhelmingly for unhealthy foods. (23) An analysis of food brands that appeared in prime-time television programming in 2008 found that children and teens saw roughly one food brand per day, and three out of four of these brand appearances were for sugary soft drinks. (29)
  • Laboratory studies find that TV food ads influence food consumption. (30,31) In one experiment, for example, children who watched cartoons with food commercials ate 45 percent more snack food while viewing than children who watched cartoons with non-food advertising. (30)
  • More evidence that exposure to food ads, rather than watching television itself, contributes to obesity comes from a study that tracked the TV viewing habits and change in BMI of 1,100 young children over a five-year period. The more hours per day of commercial TV children watched at the start of the study, the more likely they were to have a relative increase in BMI at the study’s end. There was no link between non-commercial TV watching and change in BMI. (32)

In the wake of the IOM report, Coca Cola, McDonald’s, and 15 other major food and drink companies pledged to self-regulate food advertising during U.S. television shows aimed at children under the age of 12, through the voluntary Children’s Food and Beverage Advertising Initiative (CFBAI) that launched in 2006. But loopholes exist. The guidelines don’t cover, for example, general audience prime-time shows, such as American Idol, which are often viewed by young children, and don’t cover teens; while TV food and drink advertising to children ages 2-11 decreased from 2004 to 2008, advertising to adolescents (12-17) and adults (18-49) rose substantially. (33) There’s no check to make sure that companies comply with their guidelines-and no sanctions if they don’t. In fact, a recent review of the sugary drink advertising market found that children’s and teens’ exposure to sugary soda ads doubled from 2008 to 2010, with Coca Cola (a CFBAI member) and Dr. Pepper Snapple Group (not a member) leading the way. (34)

Another problem with this U.S. food industry approach is that there are no overarching nutrition standards for what constitutes a “healthy” food or drink-and the future of such standards is a matter of hot political debate. (35) In 2009, the U.S. Congress directed the Federal Trade Commission (FTC) to form an Inter-agency Working Group on Food Marketed to Children, to develop voluntary nutrition standards for foods and drinks marketed to children, and also to define what types of marketing would be covered by the standards. But the proposed standards, released in April 2011, have been met by strong resistance from the food and beverage industry and have been stymied by Congress. (36)

Other Sedentary Behaviors and Obesity

Other sedentary behaviors-computer/Internet use, video game playing, sitting at work, driving, and the like-have have not been studied as extensively as TV watching. But there is evidence that these other forms of “sit time” can contribute to obesity.

Computer/Video Game/Internet Use

Some studies in children and teens suggest that computer, video game, and Internet use are associated with excess weight, (37–39) although not all studies have found an effect. (6,40) More and more television content is moving from TV screens to computer and smartphone screens, however, so it’s possible that clearer effects will emerge as “Generation M,” as it has been dubbed, (41) spends more and more time immersed in these new media forms. Furthermore, food and beverage companies are becoming more sophisticated and targeted in their use of digital marketing and social media across these platforms, and public health advocates have called for stronger government regulation and industry self-regulation. (35)

A newer breed of video games, so-called “active video games,” requires players to move around to control the screen. A recent small trial suggests that trading sedentary video games for active video games may help curb BMI and body fat in overweight kids, but this finding awaits confirmation by other studies. (42)

Total Time Sitting

There’s evidence that spending too much time sitting-at work or at home-increases the risk of becoming obese, (21,43) and may also increase the risk of chronic diseases and early death. (20,44,45) Of course, people who spend a lot of time sitting may spend less time being active; but physical activity levels don’t seem to explain the sitting-health risk relationship. What is unclear is whether sitting itself is the culprit, or whether sitting is just a marker of another unhealthy aspect of lifestyle-such as TV watching-that is primarily responsible for these observations. It’s also possible that other types of modern sedentary behaviors promote overeating in different ways: Reading or working on the computer, for example, may increase people’s stress and lead to overeating, while listening to music may distract people from noticing whether they are hungry or full. (46)

Driving/Riding in a Car

There have been few long-term studies on whether passive forms of transportation, such as driving or riding in a car, contribute to weight gain. One eight-year study conducted in eight provinces in China found that men who acquired a car gained four pounds more than men who did not acquire a car, and had double the odds of becoming obese. (47) Active commuting by walking or bicycling, in contrast, does offer people an opportunity to fit exercise into their days and may be a promising strategy for weight control.

The Bottom Line: Limit TV and “Sit Time,” Increase “Fit Time” to Prevent Obesity

Overall, there is little doubt that time spent watching TV is an important risk factor for obesity-and a modifiable risk factor. There’s evidence that excessive marketing of unhealthy foods and beverages on television contributes to the TV-obesity link. It remains to be seen whether there’s enough political will to implement stronger regulations or a ban on junk food TV advertising to children, though such regulations, if implemented, would likely be effective-and cost effective. (48)

But in the meantime, there are other ways to curb exposure to TV and media:

  • Parents can limit children’s screen time to no more than two hours per day, and a TV or computer ‘allowance’ device may help with setting limits. The American Academy of Pediatrics also recommends no screen time for children under the age of 2. (23)
  • Making children’s bedrooms TV-free and Internet-free-by removing TV sets or connections, or not putting them there in the first place-can also help children stay within the two-hour limit, as can turning off the TV during meals.
  • Schools, child care centers, and after-school programs can have policies that limit recreational screen time, and are also excellent venues for rolling out screen time reduction programs,such as Planet Health (17) and Eat Well and Keep Moving. (54)
  • Healthcare providers can counsel parents to limit their children’s screen time and to become advocates for stricter regulations on TV/media food and beverage advertising to children.

Staying active helps with weight control, as does limiting sedentary activities-recreational computer time, driving, and the like. So a good strategy is to replace “sit time” with “fit time”-walking or biking for part or all of a workday commute, instead of driving, or playing in the park instead of playing video games. People’s physical and social surroundings have a strong influence on how active they are, however: Without bike lanes or bicycle racks, it’s hard to bike to work, and if neighborhoods or parks are not safe, children won’t have a place to play. Creating environments that support active lifestyles will take policy change at the federal, state, and local levels, as well as the cooperation of the private sector and community groups.
