Adults Who Are Obese (BRFSS) 

The data about Adults Who Are Obese (BRFSS) come from a state-based telephone surveillance system called the Behavioral Risk Factor Surveillance System (BRFSS). BRFSS is the nation's premier system of health-related telephone surveys that collect state data about U.S. residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services. Florida is one of 50 states conducting the BRFSS with financial and technical assistance from the Centers for Disease Control and Prevention (CDC). In Florida, the BRFSS data is collected at the state level each year, and it is collected at the county level every three years.

Since behaviors impact health, this knowledge is a powerful tool for targeting and building health promotion activities. It also provides a way to see change in population health behaviors before morbidity or disease is apparent.

In 2019, in Alachua County, 29.8% Adults Who Are Obese (BRFSS) (Overall) can be compared to 27% statewide. The line graph shows change over time when there are at least three years of data.

Alachua County is in the second quartile for this measure. This means that relative to other counties in Florida, the situation occurs more often in about half of the counties, and it occurs less often in about one quarter of the counties.

The map illustrates county data by quartile. A quartile map is presented when there are at least 51 counties with data for this measure.

Data Note(s)
  • County-level surveys were previously conducted in 2002, 2007, 2010, 2013 and 2016. In 2017, the Florida Department of Health began using a three-year rolling rate methodology to provide annual county-level data. Rolling rates are calculated by combining data across several consecutive years into one measure. Survey completes from each of the 67 counties were combined across three-year periods starting with 2017-2019 to produce statistically valid county-level estimates. This new methodology was designed in collaboration with the county health departments (CHDs) to better meet programmatic needs for local-level data.
  • Caution should be taken when comparing 2013 data with previous years due to changes in survey methodology.
  • Prevalence is excluded (blank cells) from the tables for any subpopulation with a sample size less than 30, which would yield statistically unreliable estimates.
  • Confidence intervals - Because the BRFSS is a random survey and all estimates of prevalence are subject to random sample errors, we include 95% confidence intervals (CI) with each prevalence (%) in the tables. The confidence interval ranges appear below the prevalence estimates in parentheses.
  • Chart will display if there are at least three years of data.
  • Quartiles are calculated when data are available for at least 51 counties.
