According to the Centers for Disease Control and Prevention (CDC), the obesity have been affecting some groups more than others. Hispanics 47.0% and non-Hispanic blacks 46.8% had the highest age-adjusted prevalence of obesity than the non-Hispanic whites 37.9% and non-Hispanic Asians 12.7%.[10] Many explanations exist to explain the disparity, among which include different behaviors among racial and ethnic groups, differing cultural norms in regards to body weight and size, and unequal access to healthy foods.[11]
