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

Automated summary

The study found that families with private insurance were more likely to use CGM, and CGM use patterns were associated with HbA1c levels in young children with T1D in the first 18 months post-diagnosis.
