Obesity and diabetes are increasing in the United States.
In this study, researchers from Atlanta, Georgia, estimated the prevalence of obesity and diabetes among US adults in 2001.
The research team performed a random-digit telephone survey of 195,005 adults aged 18 years or older. All participants resided in states participating in the Behavioral Risk Factor Surveillance System in 2001.
The team recorded body mass index (BMI), based on self-reported weight and height, and self-reported diabetes.
|Percentage of obese adults:|
- 2000 = 20%
- 2001 = 21%

The researchers found that in 2001 the prevalence of obesity (BMI 30) was 21%, compared to 20% in 2000, an increase of over 5%.
In addition, the prevalence of diabetes increased to 8% from 7% in 2000, an increase of approximately 8%.
The team found that the prevalence of BMI of ≥40 in 2001 was 2%.
Overweight and obesity were significantly associated with diabetes, high blood pressure, high cholesterol, asthma, arthritis, and poor health status.
When the team compared adults with a BMI ≥40, with adults of normal weight, they found odds ratios of 7.37 for diagnosed diabetes, 6.38 for high blood pressure, 1.88 for high cholesterol levels, 2.72 for asthma, 4.41 for arthritis, and 4.19 for fair or poor health.
Dr Ali Mokdad's team concluded, "Increases in obesity and diabetes among US adults continue in both sexes, all ages, all races, all educational levels, and all smoking levels".
"Obesity is strongly associated with several major health risk factors".
