According to Â鶹´«Ã½AV-Healthways Daily tracking data collected between January-August 2010, an average of 26.7% of adult Americans are obese, based on their self-reported height and weight. This is on par with the 26.5% in 2009, but .
Obesity Disproportionately High Among Black Americans of All Ages

More broadly, black Americans aged 45 to 64 are the most likely of any of the racial and ethnic groups used in this analysis, at any age, to be obese, at 41%.
Previous Â鶹´«Ã½AV findings have confirmed that . Middle-aged Americans rank among the subgroups with the highest levels of obesity in the country.

Helping black, Hispanic, and middle-aged Americans reduce their weight is thus critical to meeting the Centers for Disease Control and Prevention's goal of lowering obesity prevalence to 15%. Only Asian Americans currently meet this goal.
High obesity rates among black and Hispanic Americans are in part reflective of socioeconomic differences apparent within these groups. Access to healthy foods, a place to exercise, and increased education are all important targets for decreasing obesity levels among these groups.
