Asthma – Epidemiology – Americas

DRG Epidemiology’s coverage of asthma comprises epidemiological estimates of key patient populations in 45 countries worldwide. We report the prevalence of asthma for each country, as well as annualized case counts projected to the national population.

Most patient populations are forecast over a period of 20 years for the major mature pharmaceutical markets and 10 years for the other countries covered.

DRG Epidemiology’s asthma forecast will answer the following questions:

  • How will changes in the levels of exposure to known risk or protective factors affect the number of people living with a diagnosis of asthma?
  • In developing countries, what impact will economic growth and development have on the number of people living with a diagnosis of asthma?
  • Of all people diagnosed with asthma, how many in each of the major mature pharmaceutical markets are drug-treated?
  • How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of asthma over the forecast period?

All forecast data are available on the DRG Insights Platform in tabular format, with options to download to MS Excel. All populations are accompanied by a comprehensive description of the methods and data sources used, with hyperlinks to external sources. A summary evidence table generated as part of our systematic review of the epidemiological literature is provided for full transparency into research and methods.

In addition to the total number of cases for each forecast year, DRG Epidemiology provides at least ten years of forecast data for the following asthma subpopulation:

  • Diagnosed prevalent cases by severity.

Note: Coverage may vary by country.
