Sleep and Glycemic Control in Type 2 Diabetes Adolescents

2020-01-07 08:32:20 | BioPortfolio


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.


Aim 1 will be a cross-sectional study design utilizing actigraphy watch devices to estimate sleep duration. Participants will be recruited either before or after a routine outpatient clinic visit and asked to complete intake questionnaires. They will then be provided an actigraphy watch device which will be worn for 14 days to estimate sleep duration, and Libre continuous glucose monitor (CGM) to estimate glycemic control. After their visit, clinical data will be extracted from the electronic medical record.

Aim 2 will be an interventional study design utilizing Fitbit 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.

Medical and Biotech [MESH] Definitions

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

Excessive periodic leg movements during sleep that cause micro-arousals and interfere with the maintenance of sleep. This condition induces a state of relative sleep deprivation which manifests as excessive daytime hypersomnolence. The movements are characterized by repetitive contractions of the tibialis anterior muscle, extension of the toe, and intermittent flexion of the hip, knee and ankle. (Adams et al., Principles of Neurology, 6th ed, p387)

Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
