Abstract
Background The most recent statistics released by the CDC estimate that more than one third of US adults are obese. Likely our most pressing public health concern, obesity represents a major risk factor for several of our nation’s leading causes of preventable death including heart disease, stroke, type 2 diabetes, and some forms of cancer. To compoundmatters, the annual medical cost burden associated with obesity is nearly $150 billion, with estimated expenditure being $1429 more for obese Americans each year compared with their nonobese counterparts. Although obesity affects all ages, socioeconomic strata, and racial/ethnic groups, incidence is highest in non-Hispanic blacks, followed by Mexican Americans.
