Type 1 diabetes has traditionally been studied as a chronic illness of childhood. However,
young adulthood is a critical time for the development and integration of lifelong diabetes management
skills, and research is starting to identify unique challenges faced by youth with diabetes as they
age into adulthood. Most young adults experience multiple transitions during this unstable developmental
period, including changes in lifestyle (e.g., education, occupation, living situation), changes in
health care, and shifting relationships with family members, friends, and intimate others. Young adults
with type 1 diabetes must navigate these transitions while also assuming increasing responsibility for
their diabetes care and overall health. Despite these critical health and psychosocial concerns, there is a notable lack of
evidence-based clinical services and supports for young adults with type 1 diabetes. We review relevant evolving concerns
for young adults with type 1 diabetes, including lifestyle considerations, health care transitions, psychosocial needs,
and changes in supportive networks, and how type 1 diabetes impacts and is impacted by these key developmental considerations.
Specific avenues for intervention and future research are offered.
