Risk of Disordered Eating Behaviors in Adolescents with Type 1 Diabetes

Objective Management of type 1 diabetes (T1D) may be difficult for adolescents, who often fail to meet glycemic targets. Adolescents are also at an increased risk for negative affect (i.e., anxiety, depressive symptoms) and are prone to disordered eating behaviors (DEB). This study hypothesized that negative affect would be associated with DEB, self-management, and glycemic control, but that this would be moderated by negative urgency (the urge to engage in impulsive behaviors in response to negative affect), such that this relationship would be significant only for those with higher negative urgency. Methods The Eating in Adolescents with T1D Study recruited 100 caregiver-adolescent dyads (55% male youth, 48% Caucasian) to complete questionnaires reporting on the adolescent’s negative affect, negative urgency, DEB, and diabetes management. Glycemic control 3–4 months following survey completion was extracted from the medical record. Results A total of 61% of adolescents reported elevated symptoms of anxiety or depression and 25% reported elevated disordered eating symptoms. A total of 81% of adolescents had an A1c level above recommended targets. Negative affect was associated with DEB, suboptimal T1D self-management, and suboptimal glycemic outcomes, moderated by higher levels of negative urgency. Negative affect was associated directly with suboptimal self-management and glycemic control, but not DEB, at all levels of negative urgency. Conclusions Adolescents reported high levels of negative affect, DEB, and suboptimal glycemic control. Interventions that target negative affect and negative urgency in adolescents with T1D are needed in order to reduce the risk for DEB and negative diabetes health outcomes.
