Association Between Reward Based Eating and Sleep-Wake Patterns in Patients with Obesity

Project: Research project

Project Details


The aim of this study is to examine association between sleep-wake patterns and reward-based eating in patients with obesity. Our hypothesis is that later sleep timing or more irregular sleep will be associated with greater reward-based eating. We will recruit and enroll 50 patients from the obesity clinic at Northwestern Medicine. This clinic sees and average of 50-60 unique obesity patients per month and thus our sample size goal is feasible. We will recruit equal numbers of men and women. Sleep patterns will be objectively measured over one week using water resistant wrist actigraphy monitoring (Actiwatch Spectrum Plus, Philips Respironics, Inc). We will also use wrist actigraphy to derive measures of circadian rhythms of sleep:wake behavior.We will use the 13-item Reward-based Eating Drive (RED) scale, and the Power of Food scale survey to measure appeitite. Our primary analyses will involve OLS regression models to examine associations between measures of sleep patterns and scores from the RED scale. This study will try to look into how sleep patterns can be related to eating habits/appetite which can eventually contribute to weight changes. Obesity is a really complex disease that requires a multidisciplinary approach and patient specific treatment methods in order to treat it. Identifying barriers such as sleep disturbances and reward-based eating will aid in the development of tailored, successful weight management interventions to further improve patient care and experience in clinical practice
