Sleep more, sugar less? new study tests sleep as a diabetes tool for teens
NCT ID NCT04213547
First seen Jun 26, 2026 · Last updated Jun 30, 2026 · Updated 3 times
Summary
This study explores the link between sleep duration and blood sugar control in adolescents aged 12-20 with type 2 diabetes. Researchers will first measure sleep and blood sugar in 67 teens, then test a program using Fitbits and text messages to encourage longer sleep in 15 teens who sleep less than 8 hours. The goal is to see if better sleep can improve glycemic control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sleep extension intervention (behavioral, using Fitbit and text messaging)
- What this could lead to
- If successful, this could show that improving sleep helps teens with type 2 diabetes manage their blood sugar better.
- What could go wrong
- This is a small, early-stage study with only 90 participants, so results may not apply to everyone. The sleep intervention is short-term and may not lead to lasting changes.

Inclusion Criteria: Aim 1 for child: 1. Subjects age 12-20 2. Diagnosed with T2DM by standard laboratory criteria without pancreatic autoimmunity 3. Low probability of obstructive sleep apnea (OSA) assessed via validated sleep survey 4. Subjects will be included if they are taking T2DM treatments (i.e., diet modification, Metformin and/or insulin) 5. Parental/guardian permission and child assent Aim 1 for parent: 1\. Parent or legal guardian of child that meets inclusion criteria for Aim 1. Aim 2 for child: 1. Completed Aim 1 evaluation 2. Average sleep duration \< 8 hours per night as determined by actigraphy in Aim 1 3. HbA1c ≤ 10% as HbA1c \>10 correlates to poor adherence 4. Adherence \> 80% Focus group for child: 1. Subjects aged 12-20 2. Diagnosed with type 2 diabetes without pancreatic autoimmunity Exclusion Criteria: Aim 1 for child: 1. Non-English speaking subject (as questionnaires used are validated in English) 2. Institutionalized patients as sleep duration will not be of their own accord, and therefore is not generalizable to the rest of the adolescent T2DM population. 3. Patients with other forms of Diabetes Mellitus (e.g. Type 1 Diabetes) 4. Behavioral disorders that may affect data collection (e.g. autism spectrum disorder) will be determined on a case-by-case basis. These include patients that are unable to answer questionnaires on their own, participate in a sleep diary, wear devices and/or understand incentives. 5. Oral or IV steroid treatment within the past month 6. Females with known pregnancies as these patients will not be generalizable to the rest of the adolescent T2DM population and pregnancy may alter sleep duration. 7. Subjects with known hyperthyroidism, pain syndrome, or serious medical condition that can affect sleep. 8. Subjects with hemoglobinopathies that affect hemoglobin A1c measurement. 9. Unable to obtain point-of-care hemoglobin A1c in clinic on date of recruitment 10. Known diagnosis of obstructive sleep apnea or other sleep disorder Aim 1 for Parent: 1. Non-English speaking subject (as questionnaires used are validated in English) 2. Parent/guardians with cognitive disorders that may affect data collection (determined on a case-by-case basis) Aim 2 for child: 1\. Do not own a smart phone or tablet Focus group for child: 1. Non-English speaking subject (as focus group will be conducted in English) 2. Lack of access to a computer, tablet or smartphone that can accommodate participation in video conferencing
