Quick Summary

In this randomized controlled trial, morning light exposure therapy improved sleep quality among older adults with type 2 diabetes and insomnia but did not improve glycemic control in comparison with the control condition.

What was studied?

The effects of light therapy on sleep quality, circadian rhythm, and glycemic control among adults with type 2 diabetes and insomnia in long-term care facilities.

Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and sleep monitoring bracelets were used to assess objective sleep outcomes. The Morningness-Eveningness Questionnaire (MEQ) was used to assess circadian rhythm. The MEQ includes 19 questions and classifies individuals by chronotype, such as “absolute night type”, “intermediate type”, “intermediate morning type”, and “absolute morning type”. The morning types are characterized by earlier sleep and wake times.

Morning blood samples were collected to assess glycosylated serum protein (GSP) as a measure of glycemic control.
