- Source of the data:
- The data shown in these maps were collected through CDC’s Behavioral
Risk Factor Surveillance System (BRFSS). Each year, state health
departments use standard procedures to collect data through a series of
monthly telephone interviews with U.S. adults.
- Prevalence estimates generated for the maps may vary slightly from those
generated for the states by BRFSS (http://aps.nccd.cdc.gov/brfss) as
slightly different analytic methods are used.

- During the past 20 years there has been a dramatic increase in obesity
in the United States. In 1985 only a few states were participating in
CDC's BRFSS and providing obesity data. In 1991, four states had obesity
prevalence rates of 15-19 percent and no states had rates at or above 20
percent.
- In 2004, 7 states had obesity prevalence rates of 15–19 percent; 33
states had rates of 20–24 percent; and 9 states had rates more than 25
percent.
