The data about Adults Who Are Overweight or 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 (2007, 2010, 2013, 2016 and 2019).
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 2022, in Alachua County, data was not measured for Adults Who Are Overweight or Obese (BRFSS) (Overall) compared to 66.1% statewide.
Data Source: Florida Behavioral Risk Factor Surveillance System telephone survey conducted by the Centers for Disease Control and Prevention (CDC) and Florida Department of Health Division of Community Health Promotion.
Indicators related to weight are calculated using body mass index (BMI). Obese is defined as having a BMI of 30.0 to 99.8. Overweight has a BMI of 25.0 to 29.9. Healthy or normal weight has a BMI of 18.5 to 24.9. Underweight has a BMI of 12.0 to 18.4.
*Indicators with age restrictions still have these restrictions even when presented by age group. For example, indicators that only show data for ages 50 and older will only show data for ages 50-64 in the Ages 45-64 age grouping.
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.
Quartiles are calculated when data are available for at least 51 counties.
If an indicator is not available for a particular year, it is because the question was either not asked or the survey wording changed. New questions may be added while others are removed.
