Abstract

Background: People with Type 2 diabetes frequently report increased fatigue and sleep disturbance. These symptoms might put them at a higher risk for unhealthy eating behavior-detrimental to diabetes control.

 

Objectives: The aim of the study was to examine the effect of fatigue and sleep on eating behavior in people with Type 2 diabetes by using a daily diary approach.

 

Methods: Data from 56 patients were collected during a baseline interview and an 8-day ambulatory assessment period in the free-living setting. Each day, participants completed one diary upon awakening to assess their sleep duration and sleep quality during the previous night and morning fatigue. They also completed one diary before going to bed to assess their eating behavior during the day (e.g., uncontrolled eating, cognitive restraint, emotional eating, and snacking). Data from 7 days were analyzed using generalized estimating equations.

 

Results: During the 7 days, controlling for age, gender, and body mass index, between-person fatigue was a significant predictor of uncontrolled eating, emotional eating, and snacking. Similarly, controlling for the covariates, between-person sleep quality was a significant predictor of uncontrolled eating and emotional eating. No associations were found between sleep duration and eating behavior.

 

Discussions: At the between-person level, reporting higher fatigue or poorer sleep quality was associated with higher levels of unhealthy eating behavior. Patients with Type 2 diabetes with high fatigue or poor sleep quality may require additional attention to support their healthy eating.
