Indicator Report - Asthma: Adult Prevalence

Why Is This Important?

Asthma is a serious personal and public health issue that has far reaching medical, economic, and psychosocial implications. The burden of asthma can be seen in the number of asthma related medical events, including emergency department visits, hospitalizations, and deaths.

This map was made using an interval break method called "natural breaks" where classes are based on natural groupings inherent in the data.

Data Notes

*Estimates for Summit LHD had a coefficient of variation >30% and should be interpreted with caution. Percentages have been age-adjusted to the U.S. 2000 standard population. In 2011, the BRFSS changed its methodology from a landline only sample and weighting based on post-stratification to a landline/cell phone sample and raking as the weighting methodology. Raking accounts for variables such as income, education, marital status, and home ownership during weighting and has the potential to more accurately reflect the population distribution. This graph is based on the new methodology (landline/cell phone sample; raking).

How We Calculated the Rates

Numerator: Total number of respondents answering "yes" to both of the BRFSS asthma core questions: 1. Have you ever been told by a doctor, nurse, or other health professional that you had asthma? 2. Do you still have asthma?
Denominator: Includes all survey respondents ages 18 years and older except those with missing, don't know, or refused answers to the core asthma questions.
