FinnDiane LifeOne Study - Impact of Ageing on People With Type 1 Diabetes

Healthy aging refers to functional ability that enables well-being in older individuals. The focus thus shifts from chronological age to functional capacity and the individual's own experience of well-being. Type 1 diabetes is a chronic condition characterized by elevated blood glucose levels, which increases the risk of cardiovascular diseases and premature death. However, the life expectancy of individuals with type 1 diabetes has significantly improved due to advances in diabetes care. There is limited research on aging with type 1 diabetes, and this study is at the forefront of addressing this gap by examining aging-and especially healthy aging-in type 1 diabetes from multiple perspectives. The goals are to investigate how individuals with type 1 diabetes age and what their functional capacity is compared to individuals without insulin-treated diabetes. The other aim is to identify factors in midlife that predict healthy aging in people with type 1 diabetes.
