Updated Statistics On The American Obesity Epidemic: Data From The CDC
25 Apr 2006
UroToday.com - The success of the fast food and soft drink industries has translated into an unprecedented rise in childhood and adult obesity. This epidemic has had a direct impact on our (urologists) practice due to its association with carcinogenesis in the prostate and kidney.
In the April 5 issue of JAMA, Ogden and colleagues from the CDC present updated estimates in the prevalence of childhood and adult obesity in the United States.
Height and weight measurements were recorded for 3958 children and 4431 adults in 2003 and 2004. These data, part of the National Health and Nutrition Survey, was compared from prior data from 1999 - 2000, and 2001-2002. Being overweight in children and adolescents was defined as having a BMI above the 95% for age. In adults, obesity and extreme obesity was defined as a BMI above 30 and 40, respectively.

Statistical analysis was significant for male and female children and adolescents, with a prevalence increase of overweight in female children and adolescents from 13.8% in 1999-2000 to 16.0% in 2003-2004. The prevalence of overweight in male children and adolescents rose from 14.0% to 18.2%. The prevalence of obesity in adult men rose from 27.5% to 31.1% over the period studied. No significant changes in weight were seen among women over the period studied. Significant ethnic differences persisted especially among Hispanic men and African American women.
