This study explored ways in which the COVID-19 pandemic impacted adolescents' diabetes management and psychosocial functioning, and how adolescents, parents, and providers viewed telemedicine. We present data from three studies: (1) a comparison of psychosocial functioning and glycemic levels before and after pandemic onset (n = 120 adolescents
89% with type 1 diabetes), (2) an online survey of parents about pandemic-related stressors (n = 141), and (3) qualitative interviews with adolescents, parents, and medical providers about the pandemic's impacts on adolescents' diabetes care and mental health (n = 13 parent-adolescent dyads
7 medical providers). Results suggested some adverse effects, including disrupting routines related to health behaviors and psychosocial functioning and impairing adolescents' quality of life. Despite these challenges, most participants did not endorse significant impacts. Some even noted benefits, such as increased parental supervision of diabetes management that can be leveraged beyond the pandemic. Furthermore, telemedicine offers benefits to continuity of diabetes care but presents challenges to care quality. These findings underscore the varied and unique impacts of the COVID-19 pandemic on adolescents with diabetes.
