Health Indicator Report of Asthma: Adult Prevalence
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.
Asthma Prevalence Among Adults Aged 18 and Over, Utah and U.S., 2001-2014
NotesRates have been age-adjusted to the U.S. 2000 standard population. Note: At the time of this update, the BRFSS U.S. dataset did not include an age variable but did include five age categories up to age 80+ (vs. the typical weighting scheme that includes 85+). Comparisons with both weighting schemes were compared using Utah data, and the difference was about 1/100 of a percentage point. 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.

Data Interpretation IssuesBeginning in 2011, BRFSS data include both landline and cell phone respondent data along with a new weighting methodology called iterative proportional fitting, or raking. This methodology utilizes additional demographic information (such as education, race, and marital status) in the weighting procedure. Both of these methodology changes were implemented to account for an increased number of U.S. households without landline phones and an under-representation of certain demographic groups that were not well-represented in the sample. More details about these changes can be found at: [http://health.utah.gov/opha/publications/brfss/Raking/Raking%20impact%202011.pdf].
DefinitionAdults aged 18+ (unless otherwise noted), who reported having been told by a doctor that they have asthma and who currently have asthma.
NumeratorTotal number of respondents answering "yes" to both of the BRFSS asthma core questions:[[br]] 1. Have you ever been told by a doctor, nurse, or other health professional that you had asthma?[[br]] 2. Do you still have asthma?
DenominatorIncludes all survey respondents ages 18 years and older except those with missing, don't know, or refused answers to the core asthma questions.
How Are We Doing?Adult asthma rates show no sign of declining in Utah or in the U.S. In Utah and the U.S., adult asthma prevalence is higher for women than men in almost every age category.
How Do We Compare With the U.S.?In 2014, Utah had a similar adult asthma prevalence rate when compared to the national average (8.7% vs. 8.9%).
What Is Being Done?The Utah Asthma Program (UAP) in conjunction with the Utah Asthma Task Force and other partners strive to maximize the reach, impact, efficiency, and sustainability of comprehensive asthma control services through providing a seamless alignment of the full array of services across the public health and health care sectors, so that people with asthma receive all of the services they need. The UAP focuses on three types of strategies to create and support a comprehensive asthma control program, these include: building infrastructure strategies to support leadership, strategic partnerships, strategic communications, surveillance, and evaluation; linking services strategies to expand school- and home-based services; and creating health systems strategies to improve coverage, delivery, quality, and use of clinical services. These strategies are expected to increase asthma control and quality of life, by increasing access to health care and by increasing coordination and coverage for comprehensive asthma control services both in the public health and health care sectors. Specifically, these strategies include identifying people with poorly controlled asthma, linking them to health care providers and NAEPP EPR-3 guidelines-based care, educating them on self-management, providing a supportive school environment, and referring to or providing home trigger reduction services for those who need them. The linkage function has the added benefit of bringing more people who might be high utilizers of emergency room and hospital services into primary care and also providing a resource for primary care providers to refer people for intensive self-management education and trigger reduction services when needed.
