Weight Management Behaviors are Associated with Elevated Glycemic Outcomes in Adolescents and Young Adults with Type 1 Diabetes.

Many adolescents and young adults (AYAs) with type 1 diabetes (T1D) engage in weight management behaviors (i.e., trying to lose weight), and efforts to manage weight may impact glycemic control. We assessed objective/subjective weight status and weight management behaviors in a diverse sample of 76 AYAs with T1D, and examined differences in sociodemographic characteristics and A1c levels by the following categories: (1) Overweight BMI/weight management (n = 21), (2) overweight BMI/no weight management (n = 6), (3) in/below-range BMI/weight management (n = 25), (4) in/below-range BMI/no weight management (n = 24). Subjective overweight status was more common among late adolescents and females; female gender was associated with weight management behaviors. AYAs endorsing weight management behaviors evidenced higher A1c values than those who did not. Clinicians working with AYAs should be aware of associations among weight management and glycemic indicators and routinely screen for weight management behaviors. Future research should explore interventions to promote healthy lifestyle behaviors among AYAs.
