Prevalence of Overweight in Children and Adolescents The rate of adult obesity is alarming in itself (with 65 percent of adults already overweight or obese). However, what is more alarming is that 15 percent of America’s adolescents are now obese. This represents a tripling of the rate since 1980. The rate of obesity has doubled in adults, but it has tripled in our children. Another 15 percent of America’s children are at risk of obesity. They truly are overweight, just a bit away from obesity. People who become obese in childhood are more likely to end up moderately, severely, or extremely obese in adulthood. Right now five percent of Americans are extremely obese with a BMI 40 or greater. This number will increase significantly. The CDC decided not to use the term &quot;obesity&quot; to describe children for fear of stigmatizing them, but these children meet the criteria for obesity. The Institute of Medicine just finished its 2005 conference. In this conference, they referred to obesity in children rather than overweight. A change in terminology will most likely occur.
Assessing Obesity: What is BMI? Obesity is defined by the body-mass index (BMI), which is weight in kilograms divided by height in meters squared. A “normal” BMI is between 18.5 to 24.9. Overweight starts with a BMI of 25 and goes to 29.9. There are three classes of obesity, culminating in Class III called extreme or morbid obesity, which is a BMI of 40 or greater.
Drink portion sizes This slide is a nice illustration of the portion sizes that are continually increasing. A 16 oz. serving of soda is the smallest size available at some convenience stores. Serving sizes are available up to 64 oz. at a time. Think of this as 64 ounces of sugared soda. Sixty-four times twelve, or 800 calories, in one drink. For most U.S. women, that's half their calorie need for the day.
Medical Complications of Obesity The fat cell is an endocrine cell that is part of a very large endocrine organ. Obesity leads to a whole variety of medical complications listed here under a variety of organ systems illustrated here. Almost every system is impacted by increased amount of fat, some of that because of the products of fat cell production, some of it because of increased fat mass collectively making a substantial increase in risk.
