I. Teenage Obesity
* Adolescence describes the teenage years between 13 and 19 and can be considered the transitional stage from childhood to adulthood. However, the physical and psychological changes that occur in adolescence can start earlier, during the preteen or "tween" years (ages 9-12). Adolescence can be a time of both disorientation and discovery. The transitional period can bring up issues of independence and self-identity. Sometimes adolescents may be experimenting with drugs and alcohol or sexuality. During this time, peer groups and external appearance tend to increase in importance. * According to (Elrod, 2007) Obesity is an excessive accumulation of body fat such that individuals are over 20 percent heavier than their ideal body weight. Obesity is a common eating disorder associated with adolescence. “Overweight” is defined as having any excess weight outside of the ideal range. * Overweight people of all ages are prone to a number of health problems. Some health issues associated with obesity include heart disease, diabetes, high blood pressure, stroke and some forms of cancer. * Obesity can weaken physical health and well-being, resulting in a shortened life expectancy. * It can also lead to social disabilities and unhappiness, which may cause stress and heightened risk of mental illness.
• Genetics - play a role in teenage obesity. A teenager with obese parents is 48 percent more likely to become obese than a teenager with parents who are not obese. • Socioeconomic status - is another risk factor when it comes to teenage obesity. It is common knowledge that poor, undereducated teenagers are more likely to become obese. • Lifestyle - Probably plays the biggest role in teenage obesity. A teenager who eats high- calorie foods and gets little to no physical exercise every day will be much more likely to become obese. Many families eat on the run, and this usually means eating foods with a lot of fat and sugar. •Metabolic factors - How a particular person expends energy is different from how someone else's body uses energy. Both metabolic and hormonal factors are not the same for everyone, but these factors play a role in determining weight gain. Recent studies show that levels of ghrelin, a peptide hormone known to regulate appetite, and other peptides in the stomach, play a role in triggering hunger and producing a feeling of fullness (satiety).
* The cause of teen obesity is generally Lack of physical activity combined with unhealthy eating habits. * Children today spend more time in front of a computer, video games, cell phone, and television. If you look at the statics 43% of children spend 2 hours or more in front of a television a day. The problem of teenage obesity is serious and on the rise in America today. It is estimated that 19 million American children aged 6-19, are overweight or obese. Teenage obesity is caused when a teen eats more calories than they burn off. But there are many contributing factors that make certain teen agers more likely to be obese. D. General Effects
Health effects of obesity
Obesity has a far-ranging negative effect on health. Each year obesity-related conditions cost over 100 billion dollars and cause premature deaths in the U.S. The health effects associated with obesity include, but are not limited to, the following: * High blood pressure--Additional fat tissue in the body needs oxygen and nutrients in order to live, which requires the blood vessels to circulate more blood to the fat tissue. This increases the workload of the heart because it must pump more blood through additional blood vessels. More circulating blood also means more pressure on the artery walls. Higher pressure on the artery walls increases the blood pressure. In addition, extra weight can raise the heart rate and reduce the body's ability to transport blood through the vessels. * Diabetes--Obesity is the major cause of...
