Weight Loss Center / Obesity and Diabetes: A Growing Problem Among Americans
Page: 1
Obesity and its related health problems are on the rise in the United States, as a national survey shows that Americans are becoming more obese with each passing year.
The telephone survey of over 195, 000 adults, the largest conducted to date in the United States, found a continued increase of obesity and diabetes among men and women of all ages, races and educational levels from 2000 to 2001.
During this time, obesity affected some 21 percent of Americans, a six percent increase from the previous year. In 2001, eight percent of the U.S. population suffered from diabetes, a condition often related to excess weight—an eight percent increase from 2000.
Obesity and overweight were defined by body mass index (BMI), a calculation that factors in a person’s height and weight. A BMI between 25 and 29.9 indicates overweight, 30 or above obesity.
Based on they survey findings, researchers estimate that over 21 million men and 23 million women are obese in the United States, a 74 percent increase since 1991.
Overweight and obesity are associated with several risk factors for morbidity and mortality, and those who are extremely obese have a several-fold higher risk of related health conditions.

The survey found that people whose BMIs were 40 or higher were more than seven times as likely to be diagnosed with diabetes, more than six times more likely to have high blood pressure and four times as likely to have arthritis, compared to those with normal weights. |
Researchers note that the current obesity estimates are likely substantially underestimated. Often, people underestimate their weights and overestimate their heights, which would alter their actual BMI. Moreover, those without telephones could not participate in the survey. This group of people may be of lower economic status, a condition that has been associated with obesity and diabetes. Cases of diabetes that had not been diagnosed were also not included in the study.
Obesity and the related form of diabetes are preventable, however. The CDC recommends 30 minutes of physical activity per day for good health, and 60 minutes each day for those who want to lose weight.
