DRG Epidemiology's coverage of non-alcoholic fatty liver disease (NAFLD) comprises epidemiological estimates of key patient populations across the major mature pharmaceutical markets (the United States, France, Germany, Italy, Spain, the United Kingdom and Japan). We report the prevalence of NAFLD 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 in this report.

DRG Epidemiology's NAFLD 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 NAFLD?
  • How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of NAFLD 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 also provides at least ten years of forecast data for the following NAFLD subpopulation:

  • Obesity status

Note: coverage may vary by country.

Joseph Granato joined Decision Resources Group in 2012 and previously worked on both Market Access and Global Market Access products.  Joseph is currently responsible for forecasting the prevalence and incidence of disease populations throughout the world.  He is also tasked with identifying at risk populations and developing new epidemiological methods used to predict overall population health.

He received his M.P.H. from Des Moines University where he worked on several population health projects including the delivery of continuing medical education on tick-borne diseases.  He also holds a B.S. in Animal Science from the University of Tennessee.  Prior to his time with DRG Joseph worked with the Monroe County Health Department on the surveillance of reportable diseases including Dengue Fever.
