Effect of Asthma Call-back Survey methodology changes on work-related asthma estimates, 19 states, 2007-2012.

ABSTRACT:

Objective

Asthma Call-back Survey methodology has been changed recently, as a new sampling design, weights calculation (2011-2012), and revised work-related asthma (WRA) section (2012) were implemented. To assess the effect of these changes on the WRA and possible WRA estimates among ever-employed adults with current asthma, we analyzed 2007-2012 data for 37 505 ever-employed adults (≥18 years) collected from 19 US states (representing an estimated 10 million adults each year).

Methods

Using data from landline telephone (LLP) households, we calculated estimates applying poststratification weights (2007-2010) and "raking" weights (2011-2012). Also, using data from LLP/cellular telephone (CP) households combined, we calculated estimates applying "raking" weights (2012).
