Summary

This pilot study tests whether a voice-activated smart speaker can help adults aged 50 and older with poorly controlled type 2 diabetes improve their blood sugar levels. Participants receive weekly diabetes education and skills training calls through the smart speaker for 12 weeks. Researchers will measure changes in blood sugar, blood pressure, and cholesterol, as well as feelings of depression, loneliness, and social isolation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
weekly diabetes education and skills training calls delivered through a voice-activated, touchscreen-controlled smart speaker
What this could lead to
If it works, this could offer a simple, at-home way to help older adults with diabetes better manage their blood sugar and overall health.
What could go wrong
This is a very small pilot study with only 30 participants and no comparison group, so results may not apply broadly. The intervention depends on participants being willing and able to use the smart speaker technology.
