The survey also examined scores from the Childhood Asthma Control Test and ACT to determine the level of asthma control in more than 3,000 children respondents* between the ages of 4 and 17 and found that asthma control in children is also deficient. According to the findings, 31 percent of children with asthma between the ages of 4 and 11 and 25 percent of those between 12 and 17 did not have well-controlled asthma.
About the Asthma USA Survey
The Asthma USA study was conducted by GlaxoSmithKline in cooperation with National Family Opinion Survey Group and designed to evaluate uncontrolled asthma and assess demographic variables associated with asthma risk in the general population of the United States.
This was a cross sectional mailed survey administered to a representative national sample of 134,401 households recruited from a consumer panel of households managed by NFO/TNS in May, June and July 2007, a time when asthma-related medical complications traditionally see a seasonal decline. Surveys were returned for 60.6 percent of households, including information on 10,139 adults with a self-reported physician diagnosis of asthma completing the Asthma Control Test. Data for 38,323 children aged 4 to 17 was returned with a total of 1,991 children 4 to 11 years with asthma and 1,265 adolescents 12-17 years with asthma included in the survey.
The data presented at the ATS meeting represents the first phase of the
study which is the baseline data. A subset of the initial population will
be followed on a quarterly basis to generate longitudinal data on asthma
control, missed work and school, medication use and seasonal variation in
