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

Objective: 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.

Methods: 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.

Results: Most participants (81.8%) used CGM at least once. Four CGM trajectories emerged (always, later/stable, inconsistent, and never). Participants with private insurance were more likely to be in the always, later/stable, or inconsistent groups versus the never group. Youth in the always and later/stable groups had lower mean HbA1c at 18 months than those in the never group.

Conclusions: 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.
