DRG Epidemiology’s coverage of insomnia comprises epidemiological estimates of key patient populations in the emerging pharmaceutical markets (Brazil, China, India, Mexico, Russia, South Korea, and Turkey). We report the prevalence of insomnia 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 insomnia forecast will answer the following question:

  • How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of insomnia 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 also 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 insomnia subpopulations:

  • Total DSM-IV prevalent cases by anxiety and mood disorder comorbidity status.
  • Total DSM-V prevalent cases by anxiety and mood disorder comorbidity status.
  • Total DSM-IV prevalent cases by obstructive sleep apnea comorbidity status.
  • Total DSM-V prevalent cases by obstructive sleep apnea comorbidity status.

Note: Coverage may vary by country.
