Quality-of-life measures in children and adults with type 1 diabetes: Juvenile Diabetes Research Foundation Continuous Glucose Monitoring randomized trial.

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.
