Understanding heart disease and survival in adult-onset type 1 diabetes

This is a large research study following nearly 900,000 people in Sweden to better understand the long-term health risks for adults who develop type 1 diabetes later in life. Researchers will examine medical records and data from people diagnosed with type 1 diabetes as adults between 2001 and 2020, comparing their outcomes to those of people with type 2 diabetes and people without diabetes. The goal is to learn which factors—like blood sugar control, blood pressure, and lifestyle—most affect heart health and life expectancy in adult-onset type 1 diabetes.

Type 1 diabetes is often thought of as a childhood disease, but many adults develop it for the first time. There is surprisingly little research on how this affects their risk of heart disease and survival, especially when diagnosed after age 30. This study aims to fill that gap and help doctors better predict and prevent serious complications.
