Special Issue Information

Dear Colleagues,

Sleep and nutrition are important independently modifiable health behaviours which are separately influenced by circadian factors. However, we are increasingly recognising the strong bidirectional interrelationships between these behaviours, which may increase the risk for significant health outcomes including metabolic conditions and cardiovascular disease. These outcomes may be exacerbated in vulnerable, safety-critical, or high-performing populations; or in those with sleep problems or disorders.

In this Special Issue on “Sleep and Nutrition”, we invite original research or reviews on the broad relationships between these behaviours and their influences and impacts in diverse populations (e.g., shift workers, athletes, older adults, those with sleep disorders, etc.) to further our knowledge and ultimately optimise human health and function.

Sleep disorders, which are prominent problems among college students, may be associated with skipping breakfast. Therefore, we aimed to explore the role of sleep chronotypes and depressive symptoms as mediators in the relationship between breakfast frequency and sleep quality. A cross-sectional survey enrolling random samples of 712 college students was conducted by the Questionnaire Star online platform. Statistical description and correlation analysis were performed by SPSS 25.0, and a chain mediation test was performed by model 6 in PROCESS 3.5. The result of the article demonstrated that breakfast frequency can affect sleep quality through two mediating pathways: ① sleep chronotypes, with a mediating effect of 32%; and ② depressive symptoms, with a mediating effect of 52.4%. However, the chain mediating effects of sleep chronotypes and depressive symptoms was not significant, and neither was the direct effect of breakfast frequency on sleep quality. Breakfast frequency can indirectly affect sleep quality by adjusting sleep chronotypes and depressive symptoms. Regular breakfast can increase morning and intermediate sleep chronotypes, reduce depressive symptoms, and thus improve sleep quality. Full article
