The aim of this study was to identify psychosocial factors associated with, and predictive of, diabetes self-efficacy (DSE) in young adults with youth-onset type 2 diabetes (T2D), a vulnerable, understudied group. In this observational, longitudinal study (T1 = baseline, T2 = 1 year later), 348 participants in the TODAY2 multi-center study of youth-onset T2D, completed valid measures of: diabetes self-efficacy, beliefs about medicines, depression and anxiety symptoms, diabetes distress, attitudes, self-management support, and need insecurities. Multivariable logistic regression models evaluated independent associations of each psychosocial factor with the likelihood of being in the high/low DSE tertile groups.

Introduction: Cognition is reduced at low and high glucose, reflecting cognitive vulnerability to glucose (CVG) fluctuations. The impact of glucose fluctuations on the aging brain remains unclear. We examined whether CVG is associated with plasma biomarkers of Alzheimer's disease (AD) pathology and neurodegeneration.

Introduction: Associations between amyloid-tau-neurodegeneration (ATN) plasma biomarkers and cognition have not been characterized in adults with type 1 diabetes (T1D).

Methods: Using data from participants in the Glycemic Variability and Fluctuations in Cognitive Status in Adults with T1D (GluCog) study ( = 114), we evaluated associations between phosphorylated tau (pTau)181, pTau217, β-amyloid 42/40 ratio, glial fibrillary acidic protein (GFAP), and neurofilament light (NfL) and self-administered digital cognitive tests, adjusting for age, sex, education, comorbidities (e.g.

Importance: Youth-onset type 2 diabetes is associated with poor glycemic control and early onset of complications. Identification of psychosocial factors associated with poor glycemic control is needed to inform efficacious interventions.

Objective: To identify psychosocial factors associated with glycated hemoglobin (HbA1c) levels in young adults with youth-onset type 2 diabetes.

Type 1 diabetes (T1D) is a chronic condition characterized by glucose fluctuations. Laboratory studies suggest that cognition is reduced when glucose is very low (hypoglycemia) and very high (hyperglycemia). Until recently, technological limitations prevented researchers from understanding how naturally-occurring glucose fluctuations impact cognitive fluctuations.
