Estimated life expectancy in a Scottish cohort with T1D

Life expectancy has historically been reduced in people with type 1 diabetes. In this study, researchers aimed to examine if recent advances in diabetes treatment have had an impact on this life expectancy. They analysed a large Scottish cohort and concluded that the estimated life expectancy for people with type 1 diabetes, at 20 years of age, was reduced by approximately 11 years for men and 13 years for women, compared with the general population without type 1 diabetes.

The SCI-DC (Scottish Care Information–Diabetes Collaboration) database has 24,691 people registered with type 1 diabetes who are 20 years or older (median age, 43.0 years; median duration of diabetes, 18.6 years). The researchers performed a calculation to estimate life expectancy for the general population and compared this with the group with type 1 diabetes.

The data showed that in type 1 diabetes, there was still a substantial difference in life expectancy compared with the general population: the estimated life expectancy, at 20 years of age, was reduced by approximately 11 years for men and 13 years for women. The researchers also found that renal disease remained an important factor associated with loss in life expectancy, with relative risks for death being greatly elevated in those with poorer renal function.
