THURSDAY, July 17 (HealthDay News) -- Despite wide-ranging efforts to encourage Americans to lose weight, the number of U.S. adults who are obese increased almost 2 percent between 2005 and 2007, a new report found.
In 2007, 25.6 percent of adults reported being obese, compared to 23.9 percent in 2005, according to the finding in the July 18 issue of the U.S. Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report.
"The epidemic of adult obesity continues to rise in the United States, indicating that we need to step up our efforts at the national, state and local levels," Dr. William Dietz, director of CDC's Division of Nutrition, Physical Activity, and Obesity, said in a news release. "We need to encourage people to eat more fruits and vegetables, engage in more physical activity and reduce the consumption of high-calorie foods and sugar-sweetened beverages in order to maintain a healthy weight."
The percentage of adults who are obese varies by state and region, according to the report. For example, in Alabama, Mississippi and Tennessee, 30 percent of the residents reported being obese, compared with 18.7 percent in Colorado, which had the lowest prevalence of obesity.
Obesity was most prevalent in the South, with 27 percent of residents classified as obese. In the Midwest, the number was 25.3 percent; in the Northeast, 23.3 percent; and in the West, 22.1 percent, according to the report.
In terms of age, among those 50 to 59 years old, 31.7 percent of men and 30.2 percent of women were obese. For those 19 to 29, 19.1 percent of men and women were obese.
Breaking the numbers down by race/ethnicity and sex, obesity prevalence was highest for non-Hispanic black women (39.0 percent), followed by non-Hispanic black men (32.1 percent).
Education levels play a role, too. For men, obesity prevalence was lowest among college graduates (22.1 percent) and highest among those with some college (29.5 percent) and a high school diploma (29.1 percent). For women, obesity prevalence was lowest among college graduates (17.9 percent) and highest among those with less than a high school diploma (32.6 percent).
