14-Year Longitudinal Trajectories of Depressive Symptoms Among Youth With and Without Type 1 Diabetes. (17th June 2022) - Helgeson, Vicki S
Abstract: Objective: There is evidence that youth with type 1 diabetes are at risk for depression, and depression is a significant risk factor for subsequent psychological and physical health problems. However, it is not clear if/when this depression risk emerges. The goal of this study was to determine if there are differences in levels of depressive symptoms between youth with and without type 1 diabetes that develop over the course of emerging adulthood. We also examined whether adolescent psychosocial variables predicted depressive symptoms during emerging adulthood. Methods: Youth with ( n = 132) and without ( n = 131) type 1 diabetes were enrolled in the study at average age 12 and followed for 14 years. Depressive symptoms were measured throughout the study. Psychosocial variables of interest were measured during adolescence. Results: Group differences in depressive symptoms emerged by study end at average age 26. Depressive symptoms appeared to decline over time for youth without diabetes and to increase over time for youth with diabetes. Parent relationship difficulties increased over adolescence as did peer conflict for the entire cohort. Supportive relationships with parent and peers predicted fewer end of study depressive symptoms (controlling for baseline depressive symptoms)—equally so for both groups. Conclusions: This study provides evidence that those with type 1 diabetes may be at risk for depressive symptoms many years after diagnosis and after adolescence. Although relational difficulties with parents and peers increase during adolescence, supportive relationships over the course of adolescence may help to mitigate depressive symptoms during young adulthood.
