U.S. Obesity Trends 1985 to 2002
BMI > 30, or ~ 30 lbs. overweight for 5'4" woman
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 Behavioral Risk Factor Surveillance System (BRFSS) and providing
obesity data. In 1991, four states were reporting obesity prevalence rates of
15–19 percent and no states reported rates at or above 20 percent. In
2002, 18 states have obesity prevalence rates of 15–19 percent; 29 states
have rates of 20–24 percent; and 3 states have rates over 25 percent.
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 as slightly
different analytic methods are used.
