This open-label randomized controlled trial compared culturally tailored diabetes education alone with the same education plus cyclic real-time continuous glucose monitoring (RT-CGM) in 120 Latino adults with uncontrolled type 2 diabetes at a Federally Qualified Health Center. All participants received 12 education sessions; the population was primarily Spanish-preferring and mostly not using insulin. Mean baseline HbA1c was 10.5%. At 12 weeks, HbA1c fell by 2.3% with RT-CGM versus 1.5% with education alone (P =.04). Overall improvement was maintained at 24 weeks, but the between-group difference attenuated.
Key findings
- HbA1c decreased by 1.9% overall from baseline to 12 weeks (95% confidence interval [CI]: 1.5-2.3; P < .001).
- At 12 weeks, HbA1c fell by 2.3% (95% CI: 1.5-3.2) with RT-CGM versus 1.5% (95% CI: 0.6-2.3) with blinded CGM (P =.04).
- At 24 weeks, overall HbA1c reduction was maintained, while the between-group difference attenuated.
Why it matters
The trial suggests that culturally tailored diabetes education can be associated with substantial short-term HbA1c improvement in a Latino population with poorly controlled type 2 diabetes, and that adding RT-CGM may provide additional benefit. The findings are relevant to education and glucose-monitoring approaches for populations often underrepresented in diabetes research, while the attenuated group difference at follow-up underscores uncertainty about durability.
What to keep in mind
Mean attendance was 7.0 of 12 education sessions, and mean RT-CGM wear was 27.9 days. The between-group difference attenuated by 24 weeks.
