Society statistics for Type 1 diabetes

  Costs for Type 1 diabetes: DCCT researchers estimate that intensive management doubles the cost of managing diabetes because of increased visits to a health care professional and the need for more frequent blood testing at home. However, this cost is offset by the reduction in medical expenses related to long-term complications and by the improved quality of life of people with diabetes. (Source: excerpt from Diabetes Control and Complications Trial (DCCT): NIDDK)

Cost statistics for Type 1 diabetes:

The following are statistics from various sources about costs and Type 1 diabetes:

• Estimated lifetime cost for Type 1 diabetes is about $190,000 in Australia 1993-94 (Australian Institute of Health and Welfare, 2003)
• Estimated lifetime cost for Type 2 diabetes is about $25,000 in Australia 1993-94 (Australian Institute of Health and Welfare, 2003)

About statistics:

This page presents a variety of statistics about Type 1 diabetes. The term 'prevalence' of Type 1 diabetes usually refers to the estimated population of people who are managing Type 1 diabetes at any given time. The term 'incidence' of Type 1 diabetes refers to the annual diagnosis rate, or the number of new cases of Type 1 diabetes diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
