  Asthma is a globally significant non-communicable disease with major public health consequences for both children and adults, including high morbidity, and mortality in severe cases. […] While asthma incidence and prevalence are higher in children, morbidity, and mortality are higher in adults. […] The global epidemic of asthma that has been observed in both children and adults is still continuing, especially in low to middle income countries, although it has subsided in some developed countries. […] While some important environmental determinants that trigger asthma are well-established, more work is needed to define the role of environmental exposures in the development of asthma in both children and adults. […] Therefore, there is an urgent need to further investigate the interrelationship between environmental and genetic determinants to identify high risk groups and key modifiable exposures.

  Asthma is a major noncommunicable disease (NCD), affecting both children and adults, and is the most common chronic disease among children. […] Asthma affected an estimated 262 million people in 2019 and caused 455 000 deaths. […] Most asthma-related deaths occur in low- and lower-middle-income countries, where under-diagnosis and under-treatment is a challenge. […] Asthma is often under-diagnosed and under-treated, particularly in low- and middle-income countries. […] Access to inhalers is a problem in many countries. In 2021, bronchodilators were available in public primary health care facilities in half of low- and low-middle income countries, and steroid inhalers available in one third. […] Asthma is included in the WHO Global Action Plan for the Prevention and Control of NCDs and the United Nations 2030 Agenda for Sustainable Development.

  Asthma is a chronic respiratory disease involving inflammation and narrowing of the airways that is one of the major non-communicable diseases worldwide. There are more than 300 million individuals that currently suffer from the disease and the prevalence continues to grow with each year, particularly in low and middle-income countries. […] Worldwide, it is estimated that approximately 334 million people currently suffer from asthma, and 250,000 deaths are attributed to the disease each year. The prevalence of the disease is continuing to grow, and the overall prevalence is estimated to increase by 100 million by 2025. […] In the United Kingdom, there are 5.4 million people that currently rely on treatment to manage symptoms of asthma, with 1 in 12 adults affected and 1 in 11 children. This places the UK among countries with the highest rates of prevalence of asthma in Europe. […] The prevalence of asthma in the United States is on the rise with 1 in 12 adults, approximately 25 million individuals countrywide, affected by the condition in 2009 (in comparison to 1 in 14 in 2001).

  Future initiatives in the development of KT eTools for asthma care should focus on strategies that assist healthcare providers in accurately diagnosing and documenting cases of asthma. […] A digital asthma surveillance system could support adherence to best-practice guidelines of asthma diagnosis and surveillance by prompting use of objective methods of confirmation to confirm an asthma diagnosis within the EMR. […] Globally, the number of people diagnosed with asthma is over 340 million and has continually increased over a 10-year period. […] A major contributor to the burden of asthma on individuals and the healthcare system is that gaps exist between the published guidelines for asthma diagnosis and actual strategies for diagnosis used in primary care. […] Although standards for asthma diagnosis are well established, less than half of individuals diagnosed with asthma have a confirmed diagnosis through the use of objective measurements of pulmonary function within two years of their original diagnosis.

  Epidemiology of asthma […] Asthma is a common, noncommunicable disease of the lungs affecting both children and adults. It has a global impact on health care utilization, quality of life, and mortality. The heterogeneous nature of the disease makes accurate assessment of prevalence challenging. […] The definition of asthma and the identification of affected individuals for epidemiologic purposes and data on trends in asthma prevalence will be reviewed here. […] Essential to any study of prevalence are the definition of the disease being studied and the methods available to identify affected individuals. Given the absence of a definitive laboratory test or biomarker for the diagnosis of asthma, many definitions and methods of data collection have been used and reported in epidemiologic studies; herein we discuss the most common. […] The Global Initiative for Asthma (GINA) defines asthma as, „a heterogeneous disease, usually characterized by chronic airway inflammation. It is defined by the history of respiratory symptoms such as wheeze, shortness of breath, chest tightness, and cough that vary over time and in intensity, together with variable expiratory airflow limitation.” This clinical definition is not easily translated into a form that can be used in population studies. A standard operational definition of asthma that can be used in all types of epidemiologic studies is lacking. […] A definition of asthma that was developed for epidemiologic studies to identify individuals with clinically important asthma combined wheezing in the past 12 months with AHR.

  As of 2011, approximately 235 million people worldwide were affected by asthma, and roughly 250,000 people die per year from asthma-related causes. Low and middle income countries make up more than 80% of the mortality. Prevalences vary between countries from 1% to 18%. Asthma tends to be more prevalent in developed than in developing countries. Rates are lower in Asia, Eastern Europe, and Africa. Within developed countries it is more common among those who are economically disadvantaged, but in contrast in developing countries it is more common amongst the affluent. The reason for these differences is not well known. […] The prevalence of childhood asthma in the United States has increased since 1980, especially in younger children. Rates of asthma have increased significantly between the 1960s and 2008 with it being recognized as a major public health problem since the 1970s. Some 9% of US children had asthma in 2001, compared with just 3.6% in 1980. The World Health Organization (WHO) reports that some 10% of the Swiss population have asthma as of 2007, compared with 2% some 2530 years ago. In the United States the age-adjusted prevalence of asthma increased from 7.3 to 8.2 percent during the years 2001 through 2009.

• #14 Asthma prevalence among United States population insights from NHANES data analysis | Scientific Reports

  https://www.nature.com/articles/s41598-024-58429-5

  Asthma is a prevalent respiratory condition that poses a substantial burden on public health in the United States. Understanding its prevalence and associated risk factors is vital for informed policymaking and public health interventions. This study aims to examine asthma prevalence and identify major risk factors in the U.S. population. Our study utilized NHANES data between 1999 and 2020 to investigate asthma prevalence and associated risk factors within the U.S. population. The study found that asthma affected 8.7% of the U.S. population. Gender emerged as a significant factor, with 36.0% of asthma patients being male and 64.0% female (p0.001). Individuals aged 60 and older having the highest asthma prevalence at 34.0%. Non-Hispanic whites had the highest prevalence at 46.4%, followed by non-hispanic blacks at 26.0%. In contrast, Mexican Americans and other hispanic individuals had lower rates, at 9.6% and 9.0%, respectively. Females were 1.76 times more likely to have asthma than males (p0.001). Obese individuals had a 1.74 times higher likelihood of current asthma compared to underweight individuals (p0.001). Notably, both Non-Hispanic Whites and Non-Hispanic Blacks showed higher odds of current asthma compared to Mexican Americans (with adjusted odds ratios of 2.084 and 2.096, respectively, p0.001). The research findings indicate that asthma is prevalent in 8.7% of the U.S. population. Our study highlights that individuals who are female, have low income, are obese, and smoke have the highest likelihood of being affected by asthma. Therefore, public health policies should prioritize addressing these risk factors in their preventive strategies.

  Asthma affects approximately 7% of the population of the United States and causes approximately 4,210 deaths per year. In 2005, asthma affected more than 22 million people, including 6 million children, and accounted for nearly 500,000 hospitalizations that same year. In 2010, asthma accounted for more than one-quarter of admitted emergency department visits in the U.S. among children aged 19 years, and it was a frequent diagnosis among children aged 10-17 years. From 2000 through 2010, the rate of pediatric hospital stays for asthma declined from 165 to 130 per 100,000 population, respectively, whereas the rate for adults remained about 119 per 100,000 population. […] Asthma prevalence in the U.S. is higher than in most other countries in the world, but varies drastically between ethnic populations. Asthma prevalence is highest in Puerto Ricans, Latino, African Americans, Filipinos, Irish Americans, and Native Hawaiians, and lowest in Mexicans and Koreans. Rates of asthma-related hospital admissions in 2010 were more than three times higher among African American children and two times higher for African American and Latino adults compared with White and Asian and Pacific Islander people. Also, children who are born in low-income families have higher risk of asthma.

Though there is an overall decrease in the incidence of new asthma cases in Canada, prevalence is rising. This can be attributed to a decrease in case-specific mortality due to improved management and control of asthma and its symptoms. […] It is approximated that 40 million Latin Americans live with asthma. In some reports, urban residency within Latin America has been found to be associated with an increased prevalence of asthma. Childhood asthma prevalence was found to be higher than 15 percent in a majority of Latin American countries.

  Asthma affects approximately 7% of the population of the United States and causes approximately 4,210 deaths per year. In 2005, asthma affected more than 22 million people, including 6 million children, and accounted for nearly 500,000 hospitalizations that same year. In 2010, asthma accounted for more than one-quarter of admitted emergency department visits in the U.S. among children aged 19 years, and it was a frequent diagnosis among children aged 10-17 years. From 2000 through 2010, the rate of pediatric hospital stays for asthma declined from 165 to 130 per 100,000 population, respectively, whereas the rate for adults remained about 119 per 100,000 population. […] Asthma prevalence in the U.S. is higher than in most other countries in the world, but varies drastically between ethnic populations. Asthma prevalence is highest in Puerto Ricans, Latino, African Americans, Filipinos, Irish Americans, and Native Hawaiians, and lowest in Mexicans and Koreans. Rates of asthma-related hospital admissions in 2010 were more than three times higher among African American children and two times higher for African American and Latino adults compared with White and Asian and Pacific Islander people. Also, children who are born in low-income families have higher risk of asthma.

  Asthma is a chronic disease of the airways that requires ongoing medical management. Socioeconomic and demographic factors as well as health care use might influence health patterns in urban and rural areas. Characterizing asthma indicators (i.e., prevalence of current asthma, asthma attacks, emergency department and urgent care center [ED/UCC] visits, and asthma-associated deaths) and determining how asthma exacerbations and health care use vary across the United States by geographic area, including differences between urban and rural areas, and by sociodemographic factors can help identify subpopulations at risk for asthma-related complications. […] Current asthma was higher among boys aged 18 years, women aged 18 years, non-Hispanic Black (Black) persons, non-Hispanic multiple-race (multiple-race) persons, and Puerto Rican persons. Asthma attacks were more prevalent among children, females, and multiple-race persons. ED/UCC visits were more prevalent among children, women aged 18 years, and all racial and ethnic groups (i.e., Black, non-Hispanic Asian, multiple race, and Hispanic, including Puerto Rican, Mexican, and other Hispanic) except American Indian and Alaska Native persons compared with non-Hispanic White (White) persons. Asthma deaths were higher among adults, females, and Black persons. All pertinent asthma outcomes were also more prevalent among persons with low family incomes.

  Asthma is a prevalent long-term respiratory disease that impacts millions of people across all age groups in the US, with an approximate 89% prevalence rate. According to our estimated investigation, 8.7% of the population in the United States suffers from asthma. This percentage has varied in prior U. S publications, ranging from less than 3% to more than 20%. Asthma prevalence varies by nation and is impacted by a variety of variables, including genetics, environmental circumstances, healthcare infrastructure, and lifestyle. […] Our analysis reported high asthma prevalence among those with low income. Studies consistently demonstrate that asthma is more prevalent among individuals with lower household incomes. Factors like substandard housing, exposure to environmental pollutants, and limited access to healthcare can contribute to this disparity. Lower-income individuals often face disparities in healthcare access and quality, which can lead to inadequate management of asthma and increased prevalence. They may have limited access to preventative care, medications, and asthma education. Low-income communities are more likely to be exposed to environmental triggers for asthma, such as air pollution, allergens, and tobacco smoke. These exposures can exacerbate asthma symptoms and contribute to higher prevalence rates.

  In addition, the costs of asthma hospitalizations are enormous—$763 million in 2005. This figure does not include the cost of ED visits, which are a precursor of asthma hospital admissions. Proper prevention efforts could reduce many of these poor outcomes and costs. […] In almost all measures of asthma burden, there are large disparities by race/ethnicity, income, age, gender, and geographic location.

  Asthma affects approximately 7% of the population of the United States and causes approximately 4,210 deaths per year. In 2005, asthma affected more than 22 million people, including 6 million children, and accounted for nearly 500,000 hospitalizations that same year. In 2010, asthma accounted for more than one-quarter of admitted emergency department visits in the U.S. among children aged 19 years, and it was a frequent diagnosis among children aged 10-17 years. From 2000 through 2010, the rate of pediatric hospital stays for asthma declined from 165 to 130 per 100,000 population, respectively, whereas the rate for adults remained about 119 per 100,000 population. […] Asthma prevalence in the U.S. is higher than in most other countries in the world, but varies drastically between ethnic populations. Asthma prevalence is highest in Puerto Ricans, Latino, African Americans, Filipinos, Irish Americans, and Native Hawaiians, and lowest in Mexicans and Koreans. Rates of asthma-related hospital admissions in 2010 were more than three times higher among African American children and two times higher for African American and Latino adults compared with White and Asian and Pacific Islander people. Also, children who are born in low-income families have higher risk of asthma.

  Over five million Californians have been diagnosed with asthma at some point in their lives, and almost three million currently have asthma. […] Using all of the most recent available surveillance data, this report presents a comprehensive summary of the burden of asthma in California. […] The majority of adults with asthma have mild symptoms, but about one in four have symptoms that are moderate or severe. About a third of children with asthma had an attack in the past year. […] Surveillance data show that there is much room for improvement in routine health care for people with asthma. Half of adults with asthma have not had a routine checkup for asthma in the past year and only about one-third of adults and children with asthma have received an asthma management plan. […] More encouraging is that the data indicate a decline in rates of the most severe outcomes—hospitalizations and deaths. Still, there are almost 500 deaths, 36,000 hospital discharges, and 145,000 emergency department (ED) visits (that did not result in hospitalization) per year due to asthma.

  In addition, the costs of asthma hospitalizations are enormous—$763 million in 2005. This figure does not include the cost of ED visits, which are a precursor of asthma hospital admissions. Proper prevention efforts could reduce many of these poor outcomes and costs. […] In almost all measures of asthma burden, there are large disparities by race/ethnicity, income, age, gender, and geographic location. Blacks have especially disproportionate rates of ED visits, hospitalizations, and mortality. Although people of all incomes have a similar prevalence of asthma, people with lower incomes have more severe symptoms, higher rates of hospitalizations, and are more likely to have repeat hospitalizations.

  Asthma is a chronic disease of the airways that requires ongoing medical management. Socioeconomic and demographic factors as well as health care use might influence health patterns in urban and rural areas. Characterizing asthma indicators (i.e., prevalence of current asthma, asthma attacks, emergency department and urgent care center [ED/UCC] visits, and asthma-associated deaths) and determining how asthma exacerbations and health care use vary across the United States by geographic area, including differences between urban and rural areas, and by sociodemographic factors can help identify subpopulations at risk for asthma-related complications. […] Current asthma was higher among boys aged 18 years, women aged 18 years, non-Hispanic Black (Black) persons, non-Hispanic multiple-race (multiple-race) persons, and Puerto Rican persons. Asthma attacks were more prevalent among children, females, and multiple-race persons. ED/UCC visits were more prevalent among children, women aged 18 years, and all racial and ethnic groups (i.e., Black, non-Hispanic Asian, multiple race, and Hispanic, including Puerto Rican, Mexican, and other Hispanic) except American Indian and Alaska Native persons compared with non-Hispanic White (White) persons. Asthma deaths were higher among adults, females, and Black persons. All pertinent asthma outcomes were also more prevalent among persons with low family incomes. Current asthma prevalence was higher in the Northeast than in the South and the West, particularly in small MSA areas. The prevalence was also higher in small and medium metropolitan areas than in large central metropolitan areas. The prevalence of asthma attacks differed by MSA category in four states. The prevalence of ED/UCC visits was higher in the South than the Northeast and the Midwest and was also higher in large central metropolitan areas than in micropolitan and noncore areas. The asthma mortality rate was highest in non-MSAs, specifically noncore areas. The asthma mortality rate was also higher in the Northeast, Midwest, and West than in the South. Within large MSAs, asthma deaths were higher in the Northeast and Midwest than the South and West.

  Asthma is a major noncommunicable disease (NCD), affecting both children and adults, and is the most common chronic disease among children. […] Asthma affected an estimated 262 million people in 2019 and caused 455 000 deaths. […] Most asthma-related deaths occur in low- and lower-middle-income countries, where under-diagnosis and under-treatment is a challenge. […] Asthma is often under-diagnosed and under-treated, particularly in low- and middle-income countries. […] Access to inhalers is a problem in many countries. In 2021, bronchodilators were available in public primary health care facilities in half of low- and low-middle income countries, and steroid inhalers available in one third. […] Asthma is included in the WHO Global Action Plan for the Prevention and Control of NCDs and the United Nations 2030 Agenda for Sustainable Development.

  Future initiatives in the development of KT eTools for asthma care should focus on strategies that assist healthcare providers in accurately diagnosing and documenting cases of asthma. […] A digital asthma surveillance system could support adherence to best-practice guidelines of asthma diagnosis and surveillance by prompting use of objective methods of confirmation to confirm an asthma diagnosis within the EMR. […] Globally, the number of people diagnosed with asthma is over 340 million and has continually increased over a 10-year period. […] A major contributor to the burden of asthma on individuals and the healthcare system is that gaps exist between the published guidelines for asthma diagnosis and actual strategies for diagnosis used in primary care. […] Although standards for asthma diagnosis are well established, less than half of individuals diagnosed with asthma have a confirmed diagnosis through the use of objective measurements of pulmonary function within two years of their original diagnosis.

• #77 Can a single pollen measurement site provide exposure information for health research across an entire state? Results from a study of allergic-type asthma associated with thunderstorms (2007–2018) | Journal of Exposure Science & Environmental Epidemio

  https://www.nature.com/articles/s41370-025-00777-z

  Thunderstorm asthma is an increase in severe asthma following thunderstorm events during high pollen conditions. However, sparse pollen measurements hinder epidemiological research of this phenomenon. […] Investigating thunderstorm asthma in the U.S. is challenged by sparse measurement of pollen data, with fewer than 60 stations available nationwide. […] The phenomenon of thunderstorm asthma in the U.S. remains poorly studied due to geographically sparse pollen collection sites. […] Our findings suggest that locations with plants similar to a remote pollen measurement location may have comparable daily pollen loads and provide predictive value for thunderstorm asthma research. […] Our research suggests additional pollen measurements might allow for more accurate thunderstorm asthma prediction, and previous work suggests that a greater density of pollen measurements is required. […] This study highlights the importance of additional pollen measurement in the United States for further research into this specific health outcome and other important research areas, including studies of allergenic response and the spatiotemporal spread of pollen.

• #80 Asthma prevalence among United States population insights from NHANES data analysis | Scientific Reports

  https://www.nature.com/articles/s41598-024-58429-5

  Asthma is a prevalent respiratory condition that poses a substantial burden on public health in the United States. Understanding its prevalence and associated risk factors is vital for informed policymaking and public health interventions. This study aims to examine asthma prevalence and identify major risk factors in the U.S. population. Our study utilized NHANES data between 1999 and 2020 to investigate asthma prevalence and associated risk factors within the U.S. population. The study found that asthma affected 8.7% of the U.S. population. Gender emerged as a significant factor, with 36.0% of asthma patients being male and 64.0% female (p0.001). Individuals aged 60 and older having the highest asthma prevalence at 34.0%. Non-Hispanic whites had the highest prevalence at 46.4%, followed by non-hispanic blacks at 26.0%. In contrast, Mexican Americans and other hispanic individuals had lower rates, at 9.6% and 9.0%, respectively. Females were 1.76 times more likely to have asthma than males (p0.001). Obese individuals had a 1.74 times higher likelihood of current asthma compared to underweight individuals (p0.001). Notably, both Non-Hispanic Whites and Non-Hispanic Blacks showed higher odds of current asthma compared to Mexican Americans (with adjusted odds ratios of 2.084 and 2.096, respectively, p0.001). The research findings indicate that asthma is prevalent in 8.7% of the U.S. population. Our study highlights that individuals who are female, have low income, are obese, and smoke have the highest likelihood of being affected by asthma. Therefore, public health policies should prioritize addressing these risk factors in their preventive strategies.
