Epidemiology Study: Teen Obesity
Teenage obesity is on the rise this country. In the last couple of decades, the world has changed in a startling and dramatic way. Computers, computer games, the Internet, and extended free time have pushed the numbers of teenage obesity to an alarming figure (Teen obesity, 2011). While there’s no one cause of obesity; the factors that can make someone obese are a variety of genetic, biological, behavioral, and cultural factors (AACAP, 2011). As the official website of the American Academy of Child and Adolescent Psychiatry explains, childhood obesity is often related to bad eating habits, overeating or binging, no exercise, family history, medical issues, stress or extreme life changes, family issues, low self-esteem, or depression (2011). Although a few extra pounds are not dangerous for most people; obesity is a serious health issue as it puts a definite strain on the human body. It can cause issues like an increased risk of heart disease, high blood pressure, diabetes, breathing problems, trouble sleeping (AACAP, 2011). In fact, “Teenagers who have a weight problems now—that continues to increase or stay the same in terms of their weight—will likely have a much higher risk of premature death” (Gay, 2006)(p. 26). This clearly shows the tremendous and serious threat that obesity poses for teenagers.
Demographical Data
Every individual has an ideal weight range for his or her height. An overweight person has an excess of weight outside of his or her normal range. A person can be overweight without being obese. However, for the obese person, they are 20% heavier than their ideal body weight (PAMF, 2011). While most people are aware that Americans are the most overweight country in the world, it’s not just Americans who have been steadily gaining weight since the 1960s: data shows that countries all over the world have been putting on the pounds in all genders, ethnic groups, ages and educational levels (Gay, 2006). As Gay attests from 1960 to 2000, those considered overweight in America jumped from 31.5% to 33.6% (2006). Gay cites information from the National Institute of Health which said that in 2000, 15.5% of teenagers were obese (2006). This means that a large number of teenagers today are at risk for health issues like heart disease, high cholesterol and high blood pressure as well as type 2- diabetes (Troubled Teen 101, 2011).
However, obesity disproportionately affects certain ethnic populations showing more obesity in some groups than others. For example, the National Health and Nutrition Examination Survey found that “African American and Mexican American adolescents ages 12-19 were more likely to be overweight, at 21% and 23% respectively, than non-Hispanic White adolescents 14%”(aspe.hhs.gov, 2011). This is a serious concern as type-2 diabetes is already prevalent in these ethnic groups (aspe.hhs.gov, 2011). Thus, making certain grave health conditions more of a severe hazard for certain groups and one which needs to be dealt with actively and aggressively.
Lifestyle changes that promote being sedentary, such as computer games, movies and the internet are definitely responsible for the rise in obesity, but they’re not solely to blame. Trend data suggests that certain changes in eating patterns and the nutritional composition of kids’ meals has had a direct correlation to teenage obesity (aspe.hhs.gov, 2011). The data suggests that, “In general, children and adolescents are eating more food away from home, drinking more sugar-sweetened drinks, and snacking more frequently. Convenience has become one of the main criteria for American’s food choices today, leading more and more people to consume ‘away-from-home’ quick service or restaurant meals or to buy ready-to-eat, low cost, quickly accessible meals to prepare at home” (aspe.hhs.gov, 2011). Convenience style foods, or ‘fast-food’, aside from containing a host of chemicals and preservatives in them, are often high in refined sugar, carbohydrates, and fats—ingredients, which are known to be weight-gaining. More than anything, a consumption of convenience style foods is easy to come by and make consuming them on a regular basis even easier.
Poor eating habits and a more sedentary lifestyle are obvious factors in obesity. However, there is also a link between obesity and sleep deprivation. In fact, the authors of a study concluded that the odds of obesity increased fivefold for every reduction in sleep time (Hu, 2008). There also appears to be a connection between obesity and the educational level of the parents. Parents who have experienced some college education are less likely to have obese children (Smith, 2009). Much has been made about the connection between socio-economic factors and obesity. Researchers have found that at least with women, one’s socio-economic position (SEP) has an inverse relationship with obesity. Thus, the higher the level of one’s SEP, the lower the rates for obesity in women and vice versa (Crawford, D., Jeffery, R., Ball, K., & Brug, J., 2010). This relationship was slightly less consistent for White men and no consistencies prevailed for other races (Crawford et al., 2010).
Consequences of Teenage Obesity
Teenage obesity makes it significantly more likely that a given individual will be obese into adulthood. With the direct and connected health risks that teenage obesity creates, there also go hand-in-hand the additional costs of this condition. Teenage obesity puts a direct strain on the American health care industry. “Direct medical costs may include preventive, diagnostic, and treatment services related to obesity. Indirect costs relate to morbidity and mortality costs; morbidity costs are defined as, the value of income lost from decreased productivity, restricted activity, absenteeism, and bed days” (CDC, 2011).
For example, “In 2000, the total cost of obesity for children and adults in the United States was estimated to be $117 billion, ($61 billion were in direct medical costs)” (aspe.hhs.gov, 2011). In 2008, the cost was around $147 billion (CDC, 2011). These numbers are staggering in that it clearly shows that the problem is not only getting worse, but that it continues to wage a prevalent economic toll on the professional healthcare system. Employers feel the strain of obesity on their work environments, as obese employees tend to miss more work, and register more medical and disability claims (Yale Rudd Center, 2011). In fact, the Yale Rudd Center goes so far to state that, “As a result, an average firm with 1,000 employees faces $285,000 per year in extra costs associated with obesity” (2011). This is clearly no small number or cost to any employer. Thus, there exists a strong private and public motivation to combat obesity in America, targeting it where it starts: in childhood and adolescence.
Epidemiological Triangle
An epidemiological triangle refers to a system used to understand better how diseases occur, what the forces are behind them and how they can better be fought and prevented. Specifically, an epidemiological triangle focuses on the three primary factors that have a direct effect on the “if”, “when”, “where” and “how” of diseases (Ferng, 2011). One of these factors is the disease agent and its characteristics, the host and the host’s vulnerability to the disease, and the environment that surrounds the agent and host (Ferng, 2011). It is crucial to examine these components and how they interrelate to reach a better understanding of the disease.
In one corner of the epidemiology triangle for teenage obesity there is the agent: the agent in this case would be obesity, having a weight which is 20% or more than what is considered ideal for one’s age, gender, height and bone structure (Gay, 2006). At another corner of the triangle would be the host, which would be a teenager who either has a genetic predisposition to obesity, or who has a great deal of life stress or anxiety and low self-esteem. In the final corner of the triangle would be the environment that the agent and the host reside in, that would be one that puts an emphasis on convenience foods and a sedentary lifestyle.
Psychological Factors of Teenage Obesity
The teenage years are already a tremendously vulnerable time for young people. Having a very visible issue that sparks teasing from one’s peer group can make this time even more challenging and traumatic. Many obese teens face constant teasing, taunting and poor treatment from other teens, their community, and sometimes even their family (Lüsted, 2008). As Lüsted explains, this makes such teens more likely to suffer from mental issues such as depression or even to have suicidal tendencies. In fact, “A recent study reveals that obese children rate their quality of life as low as those of young cancer patients undergoing chemotherapy” (Lüsted, 2008).
Prevention
Many of the main factors that have such a tremendous impact on obesity are easily preventable. Good parenting can have a tremendous impact on the health and well-being of children and adolescents and can be a powerful tool in combating obesity. For example, parents need to have solid knowledge and belief about proper nutrition, proper snacks for teenagers and proper portion size (Crawford et al., 2011). Furthermore, parents need to be living examples and model healthy eating and exercise behaviors. Reward and punishment systems can properly shape a child’s eating and nutritional habits size (Crawford et al., 2011). For example, junk foods like chips, sodas and cookies should not be a staple of a teenager’s diet, but rather seen as a reward for good behavior or a special treat.
Another shift that has taken place of late to reverse the obesity epidemic, is taking it from a personal problem to a public and social problem (Crawford et al., 2011). Obesity is indeed an epidemic and growing awareness is important in fighting it. From education and increased pressure to have better food labeling, readable nutritional labels on all products, to food-assistance programs that have healthier food choices and a limit on using the resources to buy unhealthy foods and fast foods, can go far in getting obesity under control. In fact many governments are exploring their options within obesity prevention programs and food regulation. For example, government regulation can have a direct effect upon the availability, composition, and accessibility of certain food products size (Crawford et al., 2011). This can be an incredibly powerful tool in fighting and precluding the obesity epidemic as it “creates a supportive environment for behavioural change” size (Crawford et al., 2011). Furthermore, documentaries like Food Inc., directed by Robert Kenner can be extremely effective tools in creating awareness about food creation and processing trends in America today in a bold and unflinching manner.
While obesity as it occurs with adolescents is a daunting problem, it is not insurmountable. Complex factors initiate and indulge in the obesity and overweight of our teens, but the drawbacks of this epidemic are so intense that it has created an environment in which people wholeheartedly want to tackle the problem. Ultimately, our future, and our children’s future will be better off because of it.

...sUnderstanding Obesity An educational resource provided by the Obesity Action Coalition What is obesity? Obesity is a disease characterized by excessive body fat. People who are affected by obesity usually are affected by behavioral, genetic and environmental factors that are difficult to control with dieting. Obesity increases the likelihood of certain diseases and other related health problems that can affect your quality of life and reduce your lifespan. Who is affected? Obesity is a serious health epidemic that affects one in three Americans. It is estimated that more than 93 million Americans are affected by obesity, with that number predicted to climb to 120 million in the next five years. “Overweight” and “Obesity” What is the difference? Stages of weight are medically defined by body mass index (BMI). An individual with a BMI of 25 to 29.9 is clinically classified as “overweight.” A BMI of 30 or more is classified as “obesity.” To determine your BMI, please view the BMI chart in the back of this brochure or visit www.ObesityAction.org Individuals affected by excess weight are also at risk for developing health problems, such as heart disease, stroke, diabetes, certain types of cancer, gout (joint pain caused by excess uric acid) and gallbladder disease. Excess weight can also cause problems such as sleep apnea (interrupted breathing during sleep) and osteoarthritis (wearing away of the joints). Weight-loss can help...

...Obesity Accumulation of excessive body fat is known as obesity. Obesity is measured and defined in terms of body mass index (BMI). Body mass index is the numerical way of deciding the appropriate weight range according to the height of an individual. A body mass index of more than 30kg/m2 indicates obesity. It is further classified as severe, morbid and super obesity in the order as the BMI increases. Obesity is a lifestyle disease which is spreading rapidly worldwide. Individuals of all age, gender and ethnicity are affected by this disease. Still, a general trend has been observed that women are affected more than the men. The tendency to gain weight also increases with the growing age. However, an alarming trend of childhood obesity is being noticed in the recent years. Obesity renders an individual susceptible to various other diseases like hypertension, coronary artery disease, type 2 diabetes, sleep apnoea etc. Obesity is mainly caused when the intake of the calories exceed the dissipated calories. In simple words, when one tends to eat more than his body requirement the extra fat start depositing in the body tissues giving rise to obesity. Junk food is the main culprit. Children are fonder of such unhealthy food items and hence are getting more affected by the rising incidences of obesity. The other common cause is the lack of physical activity. To properly digest the consumed food, physical exercise is compulsory. But the modern day sedentary life style leaves less...

...Obesity Obesity is a disease that is becoming increasingly common around the world. It is a serious medical condition that can lead to many medical issues. It is no question that America’s obesity rates are among the highest in the world. More than two-thirds of U.S. adults are overweight or obese (Ogden 2014). Obesity is on the rise among people of all ages, gender and ethnic background. The causes of obesity range from many different factors and all of them contribute to this alarming situation. Americans’ obesity has rapidly increased because of lack of physical exercise, an increase in high fat and sugary food intake, and genetic factors. Physical inactivity occurs when a person does not exercise on a daily basis. An examination of national health survey records shows Americans are exercising less, which could be driving the rising obesity rates (Bach 2014). Most people hardly exercise which is not a favorable circumstance. The percentage of women reporting no physical activity jumped from 19 percent to 52 percent between 1988 and 2010; the percentage of inactive men rose from 11 percent to 43 percent over the same period. Obesity also increased, climbing from 25 to 35 percent in women and from 20 to 35 percent in men (Bach 2014). Exercise is effective in weight loss, but most people do not accept the advantage of this preventive approach. Physical activity is rather excluded from our daily lifestyle. An excuse to not exercise is that working out is too time consuming...

...Obesity on the Rise The obesity epidemic is a very common health issue in the United States. The Center for Disease Control (2011) calls it “dangerous and expensive.” On July 8th, 2014, Medical News Today, a health news website reported that obesity in the U.S. is due to a decline in exercise, and not due to overeating. The article reports, “a study from Stanford University reported in The American Journal of Medicine suggests the rise in obesity in the US is likely due to increased sedentary lifestyles across the nation, and not eating too many calories” (Paddock, 2014, para 1). Although this health issue has received a lot of attention in the last couple of decades, the rate of obesity still continues to be high. According to the CDC, in 2011–2012, the prevalence of obesity in the U.S. has continued to increase significantly in the past 20 years; 36% of adults and 17% of children and teenagers are currently overweight. Another 17% of children and teenagers are obese (Centers for Disease Control and Prevention [CDC], 2010). The terms ‘overweight’ and ‘obese’ are determined by ‘body mass index’ or BMI. Body Mass Index (BMI) is a number determined from a person's weight and height. For an adult, a BMI from 18.5-24.9 is considered normal, a BMI between 25-29.9 is considered overweight, and a BMI greater than 30 is considered obese (CDC, 2011). This paper discusses the Medical News Today article, the topic of obesity, and how it is related to Healthy People 2020. While I agree...

Ismail (2002) claimed that 20.7% of Malaysia’s adults are overweight with a BMI between 25.0 and 29.9. According to Asia Pacific Family Medicine, obesity is a condition in which the natural energy reserve, stored in the fatty tissue of humans and other mammals, is increased to a point where it is associated with certain health conditions or increased mortality (2009). Not only adults, childhood obesity also become one of the serious problems. It grown considerably in the past two decades and most of the children are more likely become overweight adults. Obesity will lead to suffering from the disease, for example heart attack and diabetes. According to Price, Danielle and Nicholas (2000), there are around 300,000 people die each year because infect the disease that causes by obesity (as cited by Sidik and Rampal, 2009).

...Obesity and Cancer According to the National Institute of Health, nearly two-thirds of adults in the United States are overweight or obese (2007). Research suggests that obesity may be the most preventable risk factor of cancer for non-smokers, and many studies are testing for the effects that obesity has in all cancers and at specific cancer sites. It is known that obesity plays a significant role in cancer; however, the knowledge of the relationship to all cancers and the overall health effect of excess weight in terms of total mortality from cancer is limited (Calle, Redriguez, Walker-Thurmond, & Thun, 2003). In this paper I will examine the research available on obesity and its relationship to breast cancer (in post-menopausal women), endometrial, colon, esophagus, kidney, and pancreatic cancers, and briefly mention a few other cancers currently being studied for a possible link to obesity. The rise of obesity in the last 25 years has been most prominent in the United States. It is not, however, limited to the United States; for instance, similar trends are being seen in other developing countries. As it becomes easier to access tasty but unhealthy food options and as physical activity declines, caloric intake is now exceeding caloric expenditure. Genetic factors have been shown to predispose an individual to become obese, but environmental factors are the ultimate cause for the rise of obesity within populations. It is the metabolic consequences of obesity that are...

Because of on the go life styles, fast food consumption and microwave meals, people have sacrificed their health. Instead of eating pure, wholesome foods, many people opt to eat a diet of packaged, processed and refined foods. Obesity is a condition in which excess body fat has accumulated to such levels that a person’s health can be negatively affected. The US Centers for Disease Control and Prevention (CDC) have ranked obesity as the number one health threat in America, with an estimated 400,000 deaths annually. (Smoking causes an estimated 440,000 deaths annually) Being simply overweight is not as dangerous as being obese. An overweight person can easily lose a few pounds by monitored diets and exercise, and usually regains a healthy body and mind. Obese people cannot accomplish this as easily, no matter how much effort is exerted. Studies conducted by researchers at the University of North Carolina, Chapel Hill, examined three large, nationally representative surveys on food consumption conducted from 1987 to 1998.

Through solid norms and school programs such as proper nutrition standards, quality health education, quality physical education, and opportunities to do physical activity, schools can help students to adopt and maintain healthy physical and nutritional behavior. All around the country, obesity has become a great problem that affects children and adults of all races and income levels. In particular, childhood obesity is becoming a more alarming situation to address because it creates physical problems and affects mental health. The essential cause of the increase in their weight is straightforward: an excess of unhealthy eating choices compared with their physical activity. According to the National Center for Health Statistics, “An estimated 61 percent of overweight young people have at least one additional risk factor for heart disease, such as high cholesterol or high blood pressure” (National Association of State Boards Education NASBE). Consequently, social and psychological problems can emerge such as discrimination and poor self-esteem. In addition, children and young adolescents who are obese are more likely to become obese when they grow older.

Overall well-being should be the goal for weight control, not only to enhance the body’s appearance (Sobal 81). Being overweight can be helped; as any degree of obesity can be considered one of the most preventable causes of death in America (Frankle et al. 1). Obesity in the United States has grown over the years with no real solution, however vegetarianism can contribute to overall well-being of any individual. Karlsberg states that obesity is “the condition of being extremely overweight”, being usually about twenty percent over healthy weight (77). Even if one is not obese, but overweight, the problems that obesity has could be the same. Such as heart disease, circulatory problems, high blood pressure, type two diabetes, certain cancers, and arthritis (78). Other troubles associated with obesity include, but are not limited to are: impairing vigor, increasing fatigability, gallstones, cirrhosis of the liver, hardening of arteries, and the increase of surgical risks. These reasons make obesity the “prime reason for early breakdown of the human body,” says Dr. Charles Glen King, once the scientific director of Nutrition Foundation in 1964 (Diehl 120).

I believe obese children are faced with many challenges. Many of the problems travel with them throughout adult hood. I have a family member that was an obese child. She still struggles with her weight, self-esteem, and identity today and she is thirty years old. I want to explore the damaging consequences of childhood obesity. I want to take a stand against childhood obesity. I plan on limiting the topic by exposing the mental and health problems associated with childhood obesity. The Center for disease Control and Prevention says “Childhood obesity can have a harmful effect on the body in a variety of ways” (CDC, 2012, para 5). Obese children are more likely to have high blood pressure and high cholesterol, which are risk factors for cardiovascular disease (CVD). In one study, 70% of obese children had at least one CVD risk factor, and 39% had two or more. Other health problems include: Increased risk of impaired glucose tolerance, insulin resistance and type 2 diabetes; breathing problems, such as sleep apnea and asthma, joint problems and musculosketal discomfort, fatty liver disease, gall stone, and gastro-esophageal reflux (i.e., heartburn).

...Michael McCarthy PED200 Factors Influencing Obesity Did you know America is ranked as one of the most obese countries in the world? If you were to just take a second to look around the reasons are quite obvious. Fast food chains are on every block. This is because unhealthy food is so much cheaper than the healthy food that we should all be eating. Also these new technology coming out every year to make our lives easier and lazier, also high amounts of stress are all factors to weight gain in our country. A study in January 2010 shows that obesity rates have reached a constant level and stayed there for the past five years, but the levels of obesity are still unacceptable. Nearly 34 percent of American adults are obese; this number is more than double the amount of 30 years ago. And the percentage of obese children has nearly tripled in that time, to 17 percent. Are we doing enough to bring these numbers down? My opinion, is no. In the past 40 years, there has been an expansion to more than 160,000 fast-food restaurants in America. These restaurants serve more than 50 million people per day. Restaurants such as McDonald's, Hardees, and Wendy’s, serve pre-cooked, frozen foods, usually thawed out by hot oil. Now, their French fries are fried in vegetable oil, and there are now healthier side options to choose from.

It is considered to be “…the most common prevalent nutritional disorder of US children and adolescents, and one of the most common problems seen by pediatricians”( Childhood Overweight. NASO). However, it is also important to see this problem in the large problem of obesity in the country. The problem of obesity has become an increasingly serious concern for medical and healthcare authorities in recent years. The rate of obesity in developed countries like the United States has shown an alarming growth in the last decade and this has concomitant implications for healthcare professionals, including the nursing profession. The seriousness of the issue at stake is underlined by many experts in the field; for example, the claim that obesity is "... poised to become the nations leading health problem and No. 1 killer" and is "already the cause of 400,000 deaths a year...or 45 per hour..." (Hearne. S. et al, 2004) Central to the increase of general obesity is the severity of childhood obesity.

Obesity

...CHAPTER 1 INTRODUCTION Definition Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems. People are considered obese when their body mass index (BMI), a measurement obtained by dividing a person's weight in kilograms by the square of the person's height in metres, exceeds 30 kg/m2. Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders, medications or psychiatric illness. Evidence to support the view that some obese people eat little yet gain weight due to a slow metabolism is limited; on average obese people have a greater energy expenditure than their thin counterparts due to the energy required to maintain an increased body mass. Dieting and physical exercise are the mainstays of treatment for obesity.
