ClinConnect Summary

This clinical trial is studying whether treating insomnia (trouble sleeping) can help people with type 2 diabetes manage their condition better. Since many people with diabetes also have difficulty sleeping, and poor sleep can make blood sugar harder to control, the researchers want to see if a special therapy called cognitive behavioral therapy for insomnia (CBT-I) can improve both sleep and diabetes health. This therapy is a proven way to help with chronic insomnia but hasn’t been widely used in clinics that serve high-risk communities, like federally qualified health centers in Louisiana, where diabetes rates are high.

The study is looking for adults aged 40 or older who have type 2 diabetes with blood sugar levels above the recommended range and who also have significant insomnia symptoms. Participants will be randomly assigned to either receive the 8-week CBT-I program or continue with their usual diabetes care. The researchers will check sleep quality and diabetes-related health measures at the start and after three months. The goal is to see if this sleep treatment is practical and helpful in real-world healthcare settings and if it can eventually help reduce health differences seen in Louisiana. If you qualify and join, you can expect to participate in the sleep therapy sessions and have your health monitored throughout the study.
