Abstract

Breakfast intake is associated with numerous positive physical and mental health outcomes, yet breakfast skipping remains common in adults. Chronotype and sleep show potential as predictors of breakfast intake; however the existing literature has methodological limitations and fails to examine how psychological mechanisms might explain the relation between sleep and breakfast. The current investigation explored the association of means and variability of sleep behaviors (bedtime, midsleep, sleep duration) as predictors of breakfast intake frequency and high-protein breakfast intake frequency. Additionally, the role of positive and negative affect as mediators in the sleep—breakfast association was examined. Hierarchical regressions and PROCESS parallel mediation models were conducted to assess direct and indirect associations. Variability in bedtime was a significant predictor of breakfast intake frequency, with greater variability associated with less frequent intake. Future work is necessary to examine further the association of sleep and breakfast behaviors, and psychological mechanisms in this relation.
