Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study proposes to investigate whether sleep deprivation will affect a variety of measures, including hormones, immune system functioning, and behaviors related to food intake and hunger. It is predicted that sleep deprivation will affect circulating neutrophil activity, and do so via affects on DNA methylation. It is also predicted that sleep deprivation will up-regulate ghrelin, and down-regulate circulating oxytocin. Finally, it is predicted that sleep deprivation will increase participants' tendencies to pick larger portions of food, and also increase their tendency to purchase foods that are more caloric in a mock supermarket scenario.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sleep deprivation

Total sleep deprivation: participants were required to stay up for the entire night before a 'Blood Sample' was taken and the 'Neuroeconomics task' and 'Portion size task' were performed

Group Type EXPERIMENTAL

Neuroeconomics task

Intervention Type BEHAVIORAL

After a night of wakefulness, participants performed the neuroeconomics task (shopping food items in a mock supermarket scenario).

Portion Size Task

Intervention Type BEHAVIORAL

Participants are given a computer program that gives them the opportunity to choose the portions of a variety of food items that they would ideally like to consume

Blood sample

Intervention Type PROCEDURE

After a night of wakefulness, a blood sample was taken to assess the level and efficacy of circulating neutrophils, as well as to assay blood serum and plasma for the presence of hormones involved in hunger such as oxytocin and ghrelin

Sleep

Sleep: participants had an 8-h sleep opportunity before a 'Blood Sample' was taken and the 'Neuroeconomics task' and 'Portion size task' were performed

Group Type EXPERIMENTAL

Neuroeconomics task

Intervention Type BEHAVIORAL

After a night of wakefulness, participants performed the neuroeconomics task (shopping food items in a mock supermarket scenario).

Portion Size Task

Intervention Type BEHAVIORAL

Participants are given a computer program that gives them the opportunity to choose the portions of a variety of food items that they would ideally like to consume

Blood sample

Intervention Type PROCEDURE

After a night of wakefulness, a blood sample was taken to assess the level and efficacy of circulating neutrophils, as well as to assay blood serum and plasma for the presence of hormones involved in hunger such as oxytocin and ghrelin
