The highest prevalence of current asthma among U.S. children was reported in Connecticut, where 10.6 percent of all children were estimated to currently suffer from asthma. This statistic represents the prevalence of current asthma among children in the United States in 2022, by state.

As of 2021, the states with the highest lifetime prevalence of asthma among adults included New Hampshire, Rhode Island, and Vermont. In New Hampshire and Rhode Island around 17.4 percent of adults self-reported that a doctor, nurse, or other health professional had told them that you had asthma at some pinot in their lifetime. Asthma is a chronic disease affecting the airways of the lungs that can be mild or severe and can cause shortness of breath, tightness or pain in the chest, coughing, and wheezing.

The prevalence of asthma in the United States Asthma in the United States is more common among men than women, with around 8.9 percent of women with current asthma in 2021, compared to 6.5 percent of men. Current asthma is also more common among adults than children, with those aged four years and below the least likely age group to suffer from the disease. It is unclear what exactly causes asthma; however it is believed that both environmental and genetic factors play a role. In 2021, non-Hispanic Blacks were more likely to report currently suffering from asthma than their non-Hispanic white and Hispanic counterparts.

Death from asthma Medicine for asthma can help control the disease in the long-term and provide short-term relief from symptoms. Therefore, deaths from asthma in the United States are rare, with it being the underlying cause of death in about one out of every 100,000 population. The states with the highest death rates from asthma are Mississippi, Hawaii, and Oregon. In 2020, there were a total of 4,145 deaths due to asthma in the United States.

As of 2022, the prevalence of current asthma among U.S. children was around six percent. Females had higher rates of asthma than males, with almost 10 percent of females currently suffering from asthma. This statistic represents the current asthma prevalence in the United States in 2022, sorted by gender, age, and race/ethnicity.

This dataset contains the estimated percentage of Californians with asthma (asthma prevalence). Two types of asthma prevalence are included: 1) lifetime asthma prevalence describes the percentage of people who have ever been diagnosed with asthma by a health care provider, 2) current asthma prevalence describes the percentage of people who have ever been diagnosed with asthma by a health care provider AND report they still have asthma and/or had an asthma episode or attack within the past 12 months. The tables “Lifetime Asthma Prevalence by County” and “Current Asthma Prevalence by County” are derived from the California Health Interview Survey (CHIS) and include data stratified by county and age group (all ages, 0-17, 18+, 0-4, 5-17, 18-64, 65+) reported for 2-year periods. The table “Asthma Prevalence, Adults (18 and older)” is derived from the California Behavioral Risk Factor Surveillance System (BRFSS) and includes statewide data on adults reported by year.

The MarketScan health claims database is a compilation of nearly 110 million patient records with information from more than 100 private insurance carriers and large self-insuring companies. Public forms of insurance (i.e., Medicare and Medicaid) are not included, nor are small (< 100 employees) or medium (1000 employees). We excluded the relatively few (n=6735) individuals over 65 years of age because Medicare is the primary insurance of U.S. adults over 65. The EQI was constructed for 2000-2005 for all US counties and is composed of five domains (air, water, built, land, and sociodemographic), each composed of variables to represent the environmental quality of that _domain. Domain-specific EQIs were developed using principal components analysis (PCA) to reduce these variables within each _domain while the overall EQI was constructed from a second PCA from these individual domains (L. C. Messer et al., 2014). To account for differences in environment across rural and urban counties, the overall and _domain-specific EQIs were stratified by rural urban continuum codes (RUCCs) (U.S. Department of Agriculture, 2015).

In 2022, around 8.2 percent of the U.S. population currently had asthma. Over the past couple decades, the share of the U.S. population with current asthma has fluctuated. The years 2010 and 2011 saw the highest prevalence rates, with 8.5 percent in both years.

Asthma Asthma is a complicated chronic illness that affects a person’s ability to breathe. Symptoms include shortness of breath, wheezing and coughing. Asthma is treatable through avoidance of triggers and through inhaled corticosteroids (an inhaler). Prescriptions of Albuterol, a commonly prescribed inhaler, have increased significantly in the United States. Fortunately, in recent years, the out-of-pocket costs of albuterol have decreased. Asthma among the states The prevalence of asthma in U.S. states varies, with Rhode Island, Maine, and New Hampshire reporting the highest current rates of asthma. However, despite having the highest prevalence rates, these states do not have the highest death rates due to asthma. As of 2021, Mississippi and Hawaii had the highest death rates from asthma in the United States. Among all U.S. residents, the prevalence of active asthma attacks within the past 12 months has decreased over the last few years.

Note: Asthma is a condition in which your airways narrow and swell and may produce extra mucus. This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out and shortness of breath. For some people, asthma is a minor nuisance.

This dataset contains counts and rates (per 10,000 residents) of asthma emergency department (ED) visits among Californians. The table “Asthma Emergency Department Visit Rates by County” contains statewide and county-level data stratified by age group (all ages, 0-17, 18+, 0-4, 5-17, 18-64, 65+) and race/ethnicity (white, black, Hispanic, Asian/Pacific Islander, American Indian/Alaskan Native). The table “Asthma Emergency Department Visit Rates by ZIP Code” contains zip-code level data stratified by age group (all ages, 0-17, 18+). The data are derived from the Department of Health Care Access and Information emergency department database. These data include emergency department visits from all licensed hospitals in California. These data are based only on primary discharge diagnosis codes. On October 1, 2015, diagnostic coding for asthma transitioned from ICD9-CM (493) to ICD10-CM (J45). Because of this change, CDPH and CDC do not recommend comparing data from 2015 (or earlier) to 2016 (or later). NOTE: Rates are calculated from the total number of asthma emergency department visits (not the unique number of individuals).

This data shows healthcare utilization for asthma by Allegheny County residents 18 years of age and younger. It counts asthma-related visits to the Emergency Department (ED), hospitalizations, urgent care visits, and asthma controller medication dispensing events.

The asthma data was compiled as part of the Allegheny County Health Department’s Asthma Task Force, which was established in 2018. The Task Force was formed to identify strategies to decrease asthma inpatient and emergency utilization among children (ages 0-18), with special focus on children receiving services funded by Medicaid. Data is being used to improve the understanding of asthma in Allegheny County, and inform the recommended actions of the task force. Data will also be used to evaluate progress toward the goal of reducing asthma-related hospitalization and ED visits.

Regarding this data, asthma is defined using the International Classification of Diseases, Tenth Revision (IDC-10) classification system code J45.xxx. The ICD-10 system is used to classify diagnoses, symptoms, and procedures in the U.S. healthcare system.

Children seeking care for an asthma-related claim in 2017 are represented in the data. Data is compiled by the Health Department from medical claims submitted to three health plans (UPMC, Gateway Health, and Highmark). Claims may also come from people enrolled in Medicaid plans managed by these insurers. The Health Department estimates that 74% of the County’s population aged 0-18 is represented in the data.

Users should be cautious of using administrative claims data as a measure of disease prevalence and interpreting trends over time. Missing from the data are the uninsured, members in participating plans enrolled for less than 90 continuous days in 2017, children with an asthma-related condition that did not file a claim in 2017, and children participating in plans managed by insurers that did not share data with the Health Department.

Data users should also be aware that diagnoses may also be subject to misclassification, and that children with an asthmatic condition may not be diagnosed. It is also possible that some children may be counted more than once in the data if they are enrolled in a plan by more than one participating insurer and file a claim on each policy in the same calendar year.
