Quality-of-Life Measures in Children and Adults With Type 1 Diabetes

OBJECTIVE: To evaluate the impact of continuous glucose monitoring (CGM) on quality of life (QOL) among individuals with type 1 diabetes. RESEARCH DESIGN AND METHODS: In a multicenter trial, 451 children and adults with type 1 diabetes were randomly assigned to CGM treatment or the control group. Generic and diabetes-specific QOL questionnaires were completed at baseline and 26 weeks by all participants and parents of participants <18 years old, and the CGM satisfaction scale was completed by the CGM group (participants and parents) at 26 weeks. RESULTS: After 26 weeks, QOL scores remained largely unchanged for both the treatment and the control group, although there was a slight difference favoring the adult CGM group on several subscales (P < 0.05). There was substantial satisfaction with CGM technology after 26 weeks among participants and parents. CONCLUSIONS: Baseline QOL was high, and the measures showed little change with CGM use, although a high level of CGM satisfaction was reported.
