Early Type 1 Diabetes Significantly Shortens Life Expectancy


A comprehensive Swedish study provides more details about the effect of type 1 diabetes on lifespan. The study was conducted by researchers at the Sahlgrenska Academy in Sweden using data from the Swedish National Diabetes Registry. It involved 27,195 people with type 1 diabetes monitored for an average of 10 years and 135,178 controls without diabetes.

According to the study, compared with those without diabetes, women diagnosed with type 1 before age 10 have an average lifespan 18 years shorter; men diagnosed before 10 have an average lifespan 14 years shorter; and men and women diagnosed between 26 and 30 have an average lifespan 10 years shorter. While it’s well-known that type 1 diabetes reduces life expectancy, this study provides detailed information about whether and how much gender and age of onset affect life expectancy and, specifically, heart disease risk.

Severe cardiovascular disease risk is 30 percent higher in those who developed type 1 diabetes before age 10 than in those without diabetes. Women with type 1 diagnosed before age 10 have a 90 percent higher risk of heart attack than women who don’t have diabetes. Worldwide incidence of type 1 diabetes is highest in young people in Finland and Sweden.
