Introduction: Consistent continuous glucose monitor (CGM) use has been shown to improve glycemic control in patients with T1D; however, adolescents use CGMs less than any other age group. We utilized data originating from an ongoing trial at two urban diabetes centers to compare CGM use across different demographic factors.

Methods: Surveys were completed by parents (N = 150, 83% female) of adolescents with T1D (Mage 15.4 ± 1.3, MT1D duration 6.5 ± 3.7 years, MA1c 9.1 ± 2.1, 58% female, 59% White, Non-Hispanic, 19% Black, Non-Hispanic, 8% Biracial/Multicultural, 5% Hispanic, 4% Asian, 5% Other) participating in a clinical trial of a positive psychology intervention. Descriptive analyses and regression analyses were employed to compare CGM usage across different demographics. Rural communities were defined as <5,000 residents.

Results: Of the parents surveyed, 81% indicated that their adolescents currently used CGMs. There were no significant differences in adolescent CGM use related to race, X2 = 4.46, p = .49, ethnicity, X2 = 1.79, p = .18, or residence in a rural community, X2 = 0.10, p = .76. CGM use was significantly higher in teens of parents who graduated from college (87%) than those without a college degree (70%) , X2 = 6.19, p = .013. Adolescents from families with an annual income ≥ $90,000 also had higher CGM use (88%) than lower income families (72%) , X2 = 5.56, p = .018. In a multivariable model, parental education and income emerged as the significant predictors of CGM use.

Conclusions: These findings highlight significant associations between parent educational level/income and adolescent CGM use, which may reflect parents with higher SES having greater familiarity with technology. Moreover, while the diverse sample is a strength of this analysis, we did not observe previously reported differences in CGM use related to race/ethnicity. Therefore, future studies with larger samples and qualitative work with stakeholders are needed to identify predictors of CGM use.
