This document discusses trends in obesity among US adults between 1985 and 2008 based on data from the Behavioral Risk Factor Surveillance System. It shows that between 1990 and 1999, the number of states with obesity prevalence over 15% increased, and between 1999 and 2008, nearly all states had prevalence over 20% and some over 30%. The data comes from annual phone interviews conducted by state health departments to monitor health conditions and behaviors.

2. Obesity Trends Among U.S. Adults between 1985 and 2008 Definitions: Obesity: Body Mass Index (BMI) of 30 or higher. Body Mass Index (BMI): A measure of an adult’s weight in relation to his or her height, specifically the adult’s weight in kilograms divided by the square of his or her height in meters.

3. Obesity Trends Among U.S. Adults between 1985 and 2008 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 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.

4. In 1990, among states participating in the Behavioral Risk Factor Surveillance System, ten states had a prevalence of obesity less than 10% and no states had prevalence equal to or greater than 15%. By 1999, no state had prevalence less than 10%, eighteen states had a prevalence of obesity between 20-24%, and no state had prevalence equal to or greater than 25%. In 2008, only one state (Colorado) had a prevalence of obesity less than 20%. Thirty-two states had a prevalence equal to or greater than 25%; six of these states ( Alabama, Mississippi, Oklahoma, South Carolina, Tennessee, and West Virginia ) had a prevalence of obesity equal to or greater than 30%.
