• Description:
  The Asthma Call-back Survey (ACBS), a module of the Behavioral Risk Factor Surveillance System (BRFSS), collects detailed information on work-related asthma (WRA) through telephone interview using a sample of landline phone (LLP) users. Because of decreasing BRFSS response rates and increasing proportion of cellular phone (CP)-only households, iterative proportional fitting (raking) replaced the poststratification method to weight BRFSS survey data in 2011 and some states conducting ACBS added the CP user sample to the traditional LLP user sample in 2012. In addition, the wording of the WRA question was revised in 2012. To assess the effect of these three methodology changes on the proportion of asthma that is WRA we analyzed data for ever-employed adults (≥18 years) with current asthma from 19 states that consistently collected data during 2007-2012. Persons with WRA were those with physician-diagnosed WRA. We calculated estimates using poststratification weights (2007-2010) and raking weights (2011-2012) for the sample of LLP users. Also, we calculated estimates using raking weights for 2012 data collected from the combined sample of LLP/CP users. In these 19 states, based on the LLP user sample data, the prevalence of current asthma was 7.6% to 7.8% between 2007 and 2010, was 7.9% in 2011 and 2012. Of those with current asthma, the proportion of asthma that is WRA was 7.8% to 9.7% between 2007 and 2010, was 9.1% in 2011, and 15.4% in 2012. Using the 2012 LLP/CP user sample data, the prevalence of current asthma was 7.6%, of which 15.4% had WRA. Implementation of raking did not substantially change the proportion of asthma that is WRA and the estimates calculated from LLP and LLP/CP user samples in 2012 were comparable. The upward shift in the estimates in 2012 likely was associated with the revision of the ACBS WRA question. Until trends can be established with new data, the survey methodology changes should be considered when interpreting new WRA estimates. [Description provided by NIOSH]
