Project REST: Eating-related self-regulation and its neural substrates as mechanisms underlying the sleeping/eating behavior association in children with overweight/obesity: An ecological momentary assessment study


Research study that examines sleeping and eating patterns in children with overweight/obesity.

Study Type
An Ecological Momentary Assessment/Sleep Intervention
Study Purpose
Assess whether experimental manipulation of children’s sleep in the natural environment causally affects eating-related self-regulation and eating behavior overall and at the daily and momentary levels, as well as whether changes in eating-related self-regulation as a function of sleep impact subsequent eating behavior.
Study Design

This study entails 5 in-person visits over 4 weeks, including two hour-long fMRI scans. In this study, the participant will be asked to track their sleep, respond to surveys over text, and complete 24-hour dietary food recalls.

At the first visit, participants will be screened and consented by a research team member and asked to complete questionnaires. They will then undergo a one-week baseline “run-in” phase in which they will monitor naturalistic sleep and eating. At the end of the run-in phase, eligible participants will either increase or decrease their time spent in bed by 1.5 hours per night for the subsequent 7-day period. The alternate condition will be completed during the subsequent 7-day period after a 7-day wash-out period.

Study Requirements
Children aged 8-12, with overweight/obesity who report spending approximately 9.5 hours in bed per night. Participants will be excluded if they are currently taking any medications known to affect sleep, weight, or appetite, report current or past medical or psychiatric conditions known to significantly affect sleep, eating, or weight, aside from binge eating disorder, are receiving concurrent treatment for sleep disturbances or overweight/obesity, are left-handed or have metallic foreign bodies, face or neck tattoos, or other conditions that would prohibit fMRI scanning.
Study Duration
Each participant will be involved for approximately 1 month.
Study Benefits
Participants will receive compensation for all in-person study visits, plus additional incentives for completion of EMA recordings, self-initiated surveys, dietary recalls, and wash-out week sleep monitoring.
