Summary
Asthma prevalence and severity vary significantly across the U.S. based on demographics and location. Targeted public health interventions are crucial to address these persistent disparities in asthma outcomes and healthcare access.
Area of Science:
- Public Health and Epidemiology
- Environmental Health
- Health Disparities Research
Background:
- Asthma is a chronic respiratory condition requiring continuous medical management.
- Socioeconomic, demographic, and geographic factors, particularly in rural areas, influence asthma prevalence, exacerbations, and healthcare utilization.
- Understanding these variations is critical for identifying at-risk populations and improving health outcomes.
Purpose of the Study:
- To characterize asthma indicators, including prevalence, attacks, emergency department/urgent care center (ED/UCC) visits, and mortality.
- To determine variations in asthma exacerbations and healthcare use across U.S. geographic areas (urban vs. rural) and sociodemographic factors.
- To identify subpopulations at higher risk for asthma-related complications.
Main Methods:
- Utilized data from the National Health Interview Survey (NHIS) for asthma indicators (current asthma, attacks, ED/UCC visits) from 2016-2018.
- Incorporated National Vital Statistics System (NVSS) data for asthma-associated deaths.
- Analyzed trends using Metropolitan Statistical Area (MSA) categories (2006-2018) and detailed urban-rural classifications (2013 NCHS data merged with 2016-2018 NHIS data).
Main Results:
- Higher asthma prevalence observed in boys, women, non-Hispanic Black individuals, multiple-race individuals, and Puerto Rican persons.
- Increased asthma attacks in children, females, and multiple-race individuals; higher ED/UCC visits across most racial/ethnic groups compared to non-Hispanic White persons.
- Asthma mortality rates were elevated in adults, females, Black persons, and individuals with low incomes, with geographic variations noted across MSAs and urban-rural classifications.
Conclusions:
- Significant disparities in asthma indicators persist based on demographic characteristics, poverty, and geographic location, despite some improvements.
- Findings highlight the need for targeted public health programs and interventions to address these inequities.
- Data can inform strategic goals, such as the CDC's CCARE initiative, to reduce childhood asthma hospitalizations and ED visits.

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
