To better understand the local and state implications of the obesity epidemic, we ranked the nation’s heaviest cities. In doing so, we discovered states with multiple offenders, metropolitan areas with expanding waistlines and a high representation of Southern cities. Worse yet, after claiming the title of the most sedentary city, Memphis, Tenn., has also ranked first as the country’s most obese.
Behind the Numbers
To determine which cities were the most obese, we looked at 2006 data on body mass index, or BMI, collected by the Centers for Disease Control’s Behavioral Risk Factor Surveillance System, which conducts phone interviews with residents of metropolitan areas about health issues, including obesity, diabetes and exercise.
In this case, participants report their height and weight, which survey analysts use to calculate a BMI. Those with a BMI between 18.5 and 24.9 are considered at a healthy weight, those with a BMI between 25 and 29.9 are considered overweight, and those with a BMI of 30 or higher are considered obese. About 32% of the nation is obese, according to the Centers for Disease Control; Memphis ranked above the national average at 34%.
