Why This Topic Is Important
Asthma is one of the most common chronic diseases among children in the U.S. and a leading cause of pediatric hospitalization (1). It also is the top reason for missed school days, accounting for more than 5.2 million absences annually (1, 2). Asthma affects around 6 million children nationwide, at an average annual health care cost of more than $1,700 per child (2).

Asthma rates vary by region, demographics, environment, physician diagnostic practices, and access to care. Although identifying the impact of independent risk factors for asthma is difficult, children of color and those from low-income families are at disproportionately high risk for severe symptoms, missed school days, and hospital visits due to asthma (1, 3, 4). In particular, African American/black and Puerto Rican children experience a greater asthma burden compared with white children in the U.S. (1).

Asthma can be life-threatening when it is not managed properly. The CDC estimates that approximately 40% of children with asthma do not have their disease under control (5). Symptoms can be managed with regular medical monitoring and personalized action plans that help children use medicine as prescribed and to avoid asthma triggers (5, 6). However, children who face difficulty accessing quality health care are less likely to have well-controlled asthma (4, 5).

How Children Are Faring
In 2019-2020, an estimated 12% of California children ages 1-17 had been diagnosed with asthma at some point in their lives, down from 16% in 2005. While asthma does not result in hospitalization for most children, there were 7,670 hospitalizations for asthma among children ages 0-17 statewide in 2019, a rate of 8.3 hospitalizations per 10,000 children. Rates of asthma hospitalization are higher for children ages 0-4 (14.8 hospitalizations per 10,000 in 2019) than for older children ages 5-17 (6 per 10,000 in 2019). Across counties with data, 2019 asthma hospitalization rates among young children ages 0-4 ranged from fewer than 5 per 10,000 to more than 35 per 10,000.
Policy Implications
Asthma is major public health problem in the U.S., affecting an estimated 6.1 million children and 16.5 million adults, at an annual cost of more than $80 billion (1, 2). It is a leading cause of childhood hospitalizations and missed school days, with children of color—particularly African American/black children—and those from low-income families disproportionately affected by the disease (2, 3, 4). While asthma can be debilitating, even life-threatening, it usually is controllable (5). Asthma can be triggered by environmental conditions such as outdoor air pollution, tobacco smoke, and poor indoor air quality, as well as by other causes such as viral infections, exercise, and stress (2, 5). State, local, and school policies that reduce asthma triggers and that facilitate effective management and treatment of asthma can have positive effects on controlling the disease (2, 5). Effective asthma control strategies also require collaboration and commitment across multiple sectors (e.g., health care, public health, education, social services, community organizations, etc.) focused on multiple levels, including individuals, families, communities, providers, and systems (2, 5).

Policy and practice options that could influence asthma rates, management, and disparities include:
  • Ensuring that all children have adequate, accessible, and affordable health care and insurance coverage for effective prevention and treatment of asthma, including coverage for asthma medications and supplies; as part of this, ensuring that health care providers deliver coordinated care and adhere to guidelines-based management practices (2, 5)
  • Enforcing and strengthening laws and regulations that limit air pollution from vehicles, agricultural and industrial practices, and other sources; also, promoting clean diesel school buses and reducing student exposure to exhaust (2, 5)
  • Strengthening school policies to improve indoor air quality, facilitate communication and record sharing among families, schools, and health care providers, and educate students, staff, and parents on asthma care—including asthma self-management education (5)
  • Promoting integrated, community-wide interventions that decrease the burden of asthma on populations at highest risk, including outreach and education, home visiting, and reduction of asthma triggers in homes, schools, child care centers, and workplaces (5)
  • Advancing policies that go beyond poverty reduction to address structural and environmental factors associated with asthma and disproportionately experienced by some groups, such as African American/black families (4)
  • Funding local and state tobacco control efforts to reduce secondhand smoke exposure, particularly in multi-unit housing settings, restrict access to cigarettes, and increase the availability and use of smoking cessation programs (5, 6)
  • Promoting effective strategies to decrease exposure to wildfire smoke in vulnerable communities, such as providing cleaner air shelters and public education on wildfire preparedness and appropriate use of air conditioners and filters (7)
