About the Survey

The Asthma and Allergy Foundation of America (AAFA) and AstraZeneca have collaborated to conduct an extensive national survey assessing awareness and attitudes toward asthma in adults 18 years of age and older. This comprehensive survey includes the views of a robust, ethnically diverse cross-section of Americans.

Two-thirds of the asthma patients surveyed report that they have their condition under control; however, over half experience symptoms (such as shortness of breath, wheezing, coughing, chest tightness and/or phlegm production) at least once a week.

The findings from this survey not only show that control is important to those with asthma, but that asthma patients need to be better educated about how to best control the disease.

Ipsos conducted the telephone survey on behalf of AAFA and AstraZeneca between January 22, 2007, and March 4, 2007, among 4,042 U.S. adults 18 years of age and older. This included a nationally representative sample of 2,029 Americans with or without asthma (849 men and 1,180 women), and additional people were added to provide a total sample of 510 African Americans, 500 Hispanics and 616 asthma patients.

All survey data were weighted to reflect the demographic profile of Americans 18 years of age and older nationwide, in key states, in specific ethnic groups and/or of adult asthma patients, based on statistics from the U.S. Census Bureau.

In theory, with probability samples of this size, the overall sampling error for the national sample results is +/-2.2 percentage points, with 97.8% certainty. Sampling error for the various sub-sample results is higher and varies. These telephone samples are not probability samples.
