About the T1D Index

With nearly 9 million people living with type 1 diabetes (T1D) across the globe, it is one of the fastest-growing non-communicable conditions today.

The T1D Index is a first of its kind data simulation tool that measures and maps the human and public health impact of T1D. The Index uniquely illuminates the human burden of T1D by highlighting “missing people” and “healthy years lost” to the condition.

T1D has a profound human, emotional, and financial burden for those who live with it – and that burden is rising rapidly. However, simulations from the T1D Index have identified four key interventions that could change the current trajectory of T1D and its impact on people around the world. The T1D Index helps shine a light on the challenges we face, giving us a chance to act now.

How was the T1D Index developed?

The simulation is informed by 400+ publications around the globe (dating back to 1890) and a global survey of more than 500 endocrinologists. These data sources have been fitted to mathematical and machine-learning models that speak to: 

  • Rates of new cases 
  • The risk of complications and mortality
  • Prevailing standards of medical care

The T1D Index simulations provide the most accurate estimate of T1D currently available with version 1.0 testing to +/- 6 percent against real-world data. This is a significant improvement from leading existing estimates that test to +/- 35 percent against the same data. 

The T1D Index and accompanying research has been published in one of the most trusted medical journals, The Lancet Diabetes and Endocrinology.

How will the T1D Index evolve over time?

This work is the basis for a publicly available, open-source model that will be updated annually as further incidence, prevalence, and mortality data become available. In future releases, the Index will expand to include T1D’s impact on economic costs, mental health, and quality of life. The data will also be broken down at regional and demographic levels.

Who’s behind the T1D Index?

The Index was developed collaboratively by Breakthrough T1D, Life for a Child, International Society for Pediatric and Adolescent Diabetes (ISPAD), International Diabetes Federation (IDF).

These organizations represent part of the diverse global diabetes community, and this coalition is committed to working together to expand this partnership.

Our aim is to provide robust, credible data that inspires action and helps save and improve innumerable lives.

Founding T1D Index Partners

Breakthrough T1D is the leading global organization harnessing the power of research, advocacy, and community engagement to advance life-changing breakthroughs for type 1 diabetes (T1D).

Life for a Child supports children and young people living with diabetes in under-resourced communities. They partner with local clinics in 44 countries and work to ensure every young person has access to the insulin and supplies they need. Life for a Child’s vision statement is, “No child should die of diabetes.”

The International Diabetes Federation (IDF) is an umbrella organization of over 240 national diabetes associations in 160 countries and territories. IDF is engaged in action to tackle diabetes from the local to the global level, representing the interests of the growing number of people with diabetes and those at risk.

ISPAD is the International Society for Pediatric and Adolescent Diabetes. The mission of ISPAD is to create a better world for children, adolescents, and young adults with diabetes. Additionally, ISPAD, in partnership with Breakthrough T1D, funds the annual Allan Drash Clinical Fellowship, which gives members based in developing and middle income countries the opportunity to expand their clinical experience in diabetes management.
