The Sleep for Health study is testing whether treatments for sleep problems can impact blood sugar levels. Some studies have shown that people who have sleep problems are at higher risk of developing type 2 diabetes, a disease that occurs when someone’s blood sugar is too high. We are testing whether improving sleep leads to lower blood sugar in 300 people who have sleep problems and prediabetes. People with prediabetes have blood sugar levels that are higher than normal, but not yet high enough to be diagnosed as type 2 diabetes.

People are assigned randomly (by chance) to one of two study groups, either a Sleep Treatment or a Patient Education group. The Sleep Treatment group involves Cognitive Behavioral Therapy for Insomnia or “CBT-I.” This is a type of therapy that helps people find new ways to think about and respond to sleep problems. We do not know if one group is better than the other group for lowering sugar levels. People will have an equal chance of being in either group.

Visits will happen at the Center for Health Research on the Kaiser Permanente Interstate Campus. There will be three visits. The last visit will happen about 8 months after the first visit. The visits will last 2½ to 3 hours and will happen in the morning after fasting (having nothing to eat for 8 hours).

People will have their blood drawn once before drinking a sugary drink, and again two hours after that, to test their blood sugar. This will happen at each study visit.

People will also be asked questions about what they eat and how they sleep. A coin-sized sensor, called a continuous glucose monitor, will be placed on each person’s arm or stomach. Each person can choose where it is placed. The sensor is worn for 10 days, and people wearing the sensor do not need to change their activities. Participants can remove the sensor themselves after 10 days.

For 10 days after the visit, people will also be asked to wear a watch to measure their activity and sleep. Each person will be given an envelope to return the sensor and watch.

Yes. The amount will depend on which study activities you complete. You may be paid up to $400 if you complete all pre-screening steps and, if you are found to be eligible for the study, complete all study activities.

Your study payment is determined by the following:

• You will be given gift cards worth up to $35 if you complete all prescreening activities
• You will be paid after each study visit, up to $365 total across the study if you complete all visit activities

There are four prescreening activities that allow us to determine if a person is eligible to join the study. After each activity, the research team will check your results and let you know if you are eligible to continue to the next step.

1. Complete a brief website screening on this website.
2. Fill out a daily brief (3-5 minutes) online sleep diary about the previous night’s sleep for 10 days. 
3. Get a blood draw at our research center to check an A1c level, which is a measure of the sugar levels in the blood over the last 3 months. 
4. Take an at-home sleep test to make sure you do not have sleep apnea (a condition where a person stops breathing at night, causing sleep to be disrupted). This involves placing a small device on your finger while sleeping for 1 or 2 nights.
