Association of perceived diabetes stigma with time below range <3.0 mmol/L and anxiety in adults with type 1 diabetes using continuous glucose monitoring

AIMS: This study aimed to evaluate the association of stigma related to type 1 diabetes with CGM-derived data and psychological outcomes in adults with type 1 diabetes. METHODS: In this cross-sectional study, 104 adults with type 1 diabetes undergoing continuous glucose monitoring (CGM) completed the Type 1 Diabetes Stigma Assessment Scale (DSAS-1), Patient Health Questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7), and Diabetes Distress Scale (DDS). Thirty-day standard CGM data with ≥70% sensor wear time of CGM was analysed. Linear regression was used to evaluate the potential relationship between the DSAS-1 scores and CGM-derived hypoglycaemia metrics. RESULTS: Higher DSAS-1 total score was independently associated with increased time below range
