Study summary

This project investigated how glucose metabolism differs due to sleep deprivation for three consecutive nights as compared to sufficient sleep for three nights by examining concentrations of glucose, insulin, and other factors involved in glucose metabolism.

Read the detailed description

16 participants were enrolled in the study (8 females, 8 males) aged 18-25 years. In order for the participants to qualify for the study, each had to wear a pedometer for a week before the study began to determine eligibility. Each participant came to the lab for an oral glucose tolerance test on a morning, following three nights when they were sleep deprived, and on another morning when they had three nights' sufficient sleep. The sequence of the oral glucose tolerance tests were randomly assigned. The sleep duration for participants was monitored by the readings of the sleep monitors that each participant wore. The oral glucose tolerance tests were performed after an overnight fast. A 20-gauge polyethylene catheter was placed in the antecubital vein for blood sampling. Blood samples were drawn once (0 min) before and 4 times (30, 60, 90, and 120 min) after a 75g glucose drink was consumed for the determination of plasma glucose, insulin, and concentrations of other factors. Each participant was told to continue their regular routine during the study period, including diet, caffeine usage, and exercise.

Study arms

  • Experimental
    OGTT after deprived sleep first

    Participants came to the lab to perform the oral glucose tolerance test after three nights of sleep deprivation, then another test after three nights of sufficient sleep

    Behavioral: OGTT after deprived sleep first

  • Experimental
    OGTT after sufficient sleep first

    Participants came to the lab to perform the oral glucose tolerance test after three nights of sufficient sleep, then another test after three nights of deprived sleep

    Behavioral: OGTT after sufficient sleep first

Interventions

  • BehavioralOGTT after deprived sleep first

    Participants slept 1-3 hours less than their normal amount for three nights, and then came to the lab for the oral glucose tolerance testing after a 12 hour overnight fast. The second oral glucose tolerance test was after they slept as much as they wanted for three nights.

  • BehavioralOGTT after sufficient sleep first

    Participants slept as much as they wanted for three nights, and then came to the lab for the oral glucose tolerance testing after a 12 hour overnight fast. The second oral glucose tolerance test was after they slept 1-3 hours less than normal for three nights.
