BRFSS Asthma Call-back Survey

The Asthma Call-back Survey (ACBS) is an in-depth asthma survey developed and funded by the Air Pollution and Respiratory Health Branch (APRHB) in the National Center for Environmental Health (NCEH). It is conducted with Behavioral Risk Factor Surveillance System Survey (BRFSS) respondents who report an asthma diagnosis.

Asthma surveillance data at the state level includes adult and child asthma prevalence from the Behavioral Risk Factor Surveillance System (BRFSS) and in-depth state and local asthma data through implementation of the BRFSS Asthma Call-back Survey (ACBS).

The ACBS was piloted in 3 states in 2005 and has been conducted each year since. A majority of states participate in the ACBS each year.

The 2006 through 2014 ACBS data, documentation, and prevalence tables are now available through the links below.

The multiple years of data were adjusted to represent an average individual year lifetime asthma population for each state. Based on the annual BRFSS child lifetime asthma population estimates, each year’s total estimated child lifetime asthma population was proportionately adjusted to represent that year’s relative contribution to multiple years of combined data. After the proportionate adjustment for the estimated lifetime asthma population, the weights were further adjusted by post-stratifying for differential non-response by demographic subgroups. The final weight for multiple years
(2012–2014) ACBS data is _CHILDWT_M_YEARS.
