Patterns of Continuous Glucose Monitor Use in Young Children Throughout the First 18 Months Following Type 1 Diabetes Diagnosis

To describe sociodemographic and parent psychosocial characteristics associated with patterns of continuous glucose monitor (CGM) use across the first 18 months post-type 1 diabetes (T1D) diagnosis among young children. One hundred fifty-seven parent-child dyads enrolled in a behavioral intervention for parents of young children (1-6 years) newly diagnosed with T1D. Parents reported on baseline sociodemographic characteristics and psychosocial functioning; child CGM use was assessed at five time points during the first 18 months post-diagnosis. Most participants (81.8%) used CGM at least once. Four CGM trajectories emerged ( and . Participants with private insurance were more likely to be in the , , or groups versus the group. Youth in the and groups had lower mean HbA1c at 18 months than those in the group. Given the health benefits of CGM, further exploration of barriers to CGM use in families with public health insurance is needed. ClinicalTrials.gov identifier: NCT02527525.
