About this trial
The primary objective is to determine the cross-sectional relationship between sleep duration (as measured by 14 days of actigraphy) and glycemic control in an adolescent Type 2 Diabetes (T2DM) cohort (age 12-20y, n=67). A secondary objective is to determine if a loss-framed incentive for achieving sleep goals can increase sleep duration in 15 adolescent patients diagnosed with T2DM with insufficient sleep. Another secondary objective is to test if increasing sleep duration leads to improved glycemic control in 15 adolescents with T2DM identified in Aim 1 as having \<8 hr sleep/evening. A focus group will be conducted prior to this intervention with patients ineligible for the intervention in order to determine appropriate text messaging.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Subjects age 12-20
Diagnosed with T2DM by standard laboratory criteria without pancreatic autoimmunity
Low probability of obstructive sleep apnea (OSA) assessed via validated sleep survey
Subjects will be included if they are taking T2DM treatments (i.e., diet modification, Metformin and/or insulin)
Disqualifiers
Non-English speaking subject (as questionnaires used are validated in English)
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.
Patients with other forms of Diabetes Mellitus (e.g. Type 1 Diabetes)
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.
Trial design
Single group
Treatments tested in this trial
Loss frame sleep extension intervention
BehavioralAim 2 will be an interventional study design utilizing Fitbit and text messaging to perform a loss-framed incentive intervention designed to motivate participants to increase their sleep duration. Glycemic control will be measured via laboratory testing of hemoglobin A1c and Libre continuous glucose monitoring (CGM) for 2 weeks pre- and post-intervention. A focus group will be conducted prior to this intervention with patients ineligible for the intervention in order to determine appropriate text messaging.
Treatment groups
Trial outcomes
Primary outcomes
Sleep duration (for Aim 2)
Will assess for sleep extension throughout intervention
Hemoglobin A1c (for Aim 1)
Aim 1 is assessing cross-sectional relationship of A1c to sleep duration

Aim 1 is assessing cross-sectional relationship of BMI to sleep duration
Qualitative data from focus group
Qualitative output from focus group discussion on text messages
Secondary outcomes
Glycemic control
Will assess for change in hemoglobin a1c throughout intervention
Glycemic control
Will assess for change in continuous glucose monitor measures throughout intervention
BMI
Will assess for change in body mass index (BMI) throughout intervention
