Facts on Obesity in America
In recent years, awareness of the American obesity problem has increased. As Americans become more health-conscious, research into the causes of obesity has progressed, and scientists now know more than ever about the causes and prevention of obesity. Nevertheless, the staggering number of obese Americans remains, and educating citizens about the risks of obesity is still a crucial element in developing a healthy society.

Identification
-
Obesity is a condition defined by a person's weight. Although genetics may increase the risk of obesity, this is not proven, and many individuals with a long family history of obesity do not inherit the disease. According to the American Obesity Association, Body Mass Index (BMI) measurement is the primary factor in determining obesity. BMI is calculated by dividing weight in pounds by height in inches squared, and then multiplying by 704.5. If the result is greater than 30, obesity is diagnosed. "Obesity" and "overweight" are two distinct terms; overweight BMI measurements range from 25 to 29. Other methods for determining obesity include height/weight tables, measurement of waist circumference, and combined methods.
Statistics
-
A shocking one-third of American adults are obese (63.6 million). In children, obesity is also prevalent, and around 17 percent of American children are overweight or obese.
Development
-
According to the Weight Control Information Network, the rate of obesity in America has increased in the last 50 years. In 1960, the rate of obesity among American adults (ages 20 to 74) was 13.3 percent. In 2004, it had increased to 32.1 percent. Most of the change occurred after the `1980s.
Causes of Obesity
-
In recent years, scientists have discovered that there may be genetic links involved in obesity. According to the AOA, a person's genetic background can increase the risk of becoming obese. However, many people who have obesity in their genes do not become obese. This demonstrates that other factors must be involved. These factors are environment and behavior. Many people who do not have obesity in their genes go on to become obese due to an unhealthy, inactive environment. Lifestyle and behavior radically alter the chances of becoming obese. Many health advocates and doctors suggest that the increase in obesity may be due to the increase of processed foods, fast foods, and the lack of an active lifestyle that has been on the rise in the past few decades.
Obesity Related Deaths in America
-
Obesity is estimated to cause about 300,000 deaths in the U.S. every year, according to the American Obesity Association. It also causes many other serious health conditions, such as diabetes, heart disease and high blood pressure.
Effects on Economy
-
Studies have shown that obesity not only affects individuals; it also drains the economy. According to WIN, overweight and obese conditions cost a total of $117 billion per year in medical expenses. Obesity also affects productivity, and an estimated $3.9 billion a year is lost due to weight-caused illnesses.
