Digital health technologies (DHT) are increasingly being utilized in the modern management of diabetes. DHT includes continuous glucose monitoring systems, connected blood glucose monitoring devices, hybrid closed-loop systems, smart insulin pens, telehealth, and smartphone applications.

This article describes barriers to their use and offers recommendations on how to overcome these barriers and expand access to DHT for underserved populations, which would be expected to improve outcomes for people living with diabetes.

The article tends to focus on the current “situation” and experience of minoritized communities in the USA; however, it is likely that the principles are generalizable to other countries and healthcare systems with racial, ethnic, and economic disparities.

Is Table 2 necessary? The authors have not provided similar tabular evidence for T1D and T2D.

The revised manuscript is improved.

Although most readers will know what PWD refers to, nonetheless, the abbreviation PWD should be defined.

In the edited version, digital health technology is spelled out in full until P34/70 line 12 when DHT appears for the first time. Later, digital health technology is used again. It would be acceptable to abbreviate throughout the manuscript.
