Key Takeaways
- Gestational diabetes affected 14.8% of pregnancies in 2016–2020 in the U.S. (CDC/NIH reported national estimate)
- The percentage of pregnancies affected by diabetes (pre-existing or gestational) in Australia was 7.2% in 2018 (Australian Institute of Health and Welfare)
- Diabetes prevalence among adults in Canada was 10.3% in 2020/21 (Public Health Agency of Canada estimate)
- In England, there were 3.2 million people known to have diabetes in 2022/23 (NHS Digital)
- Diabetes cost the U.S. healthcare system $327 billion in 2017 with $162B attributable to diagnosed and $164B to undiagnosed diabetes (ADA)
- In Australia, the estimated national cost of diabetes in 2019 was AUD 20.5 billion (AIHW)
- Type 2 diabetes patients using CGM had a 0.6% greater HbA1c reduction than those not using CGM in trials (meta-analysis, published 2021)
- Continuous glucose monitoring improved time-in-range by about 12 percentage points vs control in randomized trials (systematic review 2020)
- In the UKPDS, risk reduction for microvascular complications was 25% with intensive control (UKPDS 33; 1998)
- 6.7 million deaths were attributable to diabetes and its causes in 2021
- 14.8% of adults with diabetes in the US reported not taking recommended diabetes medications in 2021
- The global diabetes therapeutics market is forecast to reach $142.6 billion by 2030
- The global diabetes diagnostics market is forecast to reach $61.0 billion by 2030
- Diabetes reduced life expectancy by 4.0 years for people with type 1 diabetes (relative to non-diabetes populations)
- People with diabetes had a 2.1x higher risk of major cardiovascular events than people without diabetes (pooled estimate)
Diabetes affects millions worldwide, costing billions, while newer monitoring and glucose lowering treatments can meaningfully reduce risks.
