Abstract
in English, French

Introduction: In the past decade, investigations of the relationship between sleep duration and eating behaviours have been emerging; however, a formal synthesis of the literature focussed on adolescent populations has not yet been conducted. We conducted a scoping review of the literature examining the relationship between sleep duration and eating behaviours in adolescents. Gaps in the research and directions for future research were identified based on the findings.

Methods: A systematic search was employed on four research databases: PubMed, PsycInfo, CINAHL and Scopus; relevant grey literature was also reviewed. Studies that reported on the relationship between sleep duration and eating behaviours among high school-aged adolescents were included in the review. Data were extracted, charted and synthesized into a narrative. Consistent with the purpose of a scoping review, the methodological quality of the studies was not appraised. Stakeholders were consulted to validate the findings and provide insight into the interpretation and identification of pressing gaps in the research that remain to be addressed.

Results: In total, 61 studies published between 2006 and 2021 met the criteria for review. Existing research focussed heavily on examining sleep duration in relation to intake of food from certain food groups, beverages and processed foods, and relied on a population study design, cross-sectional analyses and self-report measures.

Conclusion: Future research is needed to understand the link between sleep duration and eating-related cognition, eating contexts and disordered eating behaviours in order to better understand how ensuring sufficient sleep among adolescents can be leveraged to support healthier eating practices and reduce diet-related risks.

Introduction: Au cours de la dernière décennie, diverses études sur la relation entre la durée du sommeil et les comportements alimentaires ont vu le jour mais il n'existe encore aucune synthèse formelle de la littérature axée sur les populations adolescentes. Nous avons donc mené un examen de la portée de la littérature concernant la relation entre la durée du sommeil et les comportements alimentaires chez les adolescents. Nous avons relevé les lacunes dans la recherche et les perspectives de recherche en fonction des résultats.

Méthodologie: Une recherche systématique a été effectuée dans quatre bases de données de recherche : PubMed, PsycInfo, Cumulative Index to Nursing et Allied Health Literature (CINAHL) et Scopus. La littérature grise pertinente a également été examinée. Nous avons inclus les études portant sur la relation entre la durée du sommeil et les comportements alimentaires chez les adolescents en âge de fréquenter l'école secondaire. Les données ont été extraites, structurées et synthétisées sous forme narrative. Conformément à l'objectif d'un examen de la portée, la qualité méthodologique des études n'a pas été évaluée. Nous avons consulté des intervenants afin de valider les résultats et d'éclairer l'interprétation et la détermination des lacunes de la recherche qui restent à combler de manière urgente.

Résultats: Au total, 61 études publiées entre 2006 et 2021 ont répondu aux critères d'examen. Les recherches portaient principalement sur l'examen de la durée du sommeil en relation avec la consommation de certains groupes alimentaires, de boissons et d'aliments transformés. Elles s'appuyaient sur des études en population, des analyses transversales et des mesures d'auto-évaluation.

Conclusion: D'autres recherches sont nécessaires pour comprendre le lien entre la durée du sommeil et la cognition liée à l'alimentation, les contextes d'alimentation et la perturbation des comportements alimentaires, de façon à ce que l'on comprenne mieux comment la promotion d'un sommeil suffisant chez les adolescents contribuerait à soutenir des pratiques alimentaires plus saines et à réduire les risques liés à l'alimentation.

Plain language summary

Unique to this study, we reviewed the breadth of the literature related to sleep duration, dietary intake and eating habits among adolescents. We found a large emphasis on the dietary intake of healthful foods, beverages and processed foods, and limited focus on the contextual factors that shape eating, eating-related cognitions and disordered eating symptoms. Stakeholders validated the findings, provided insight into the interpretation of the findings and highlighted areas for future research. Additional sleep research exploring the cognitive and contextual factors surrounding eating is needed (e.g. eating with others, eating when not hungry, binge eating).
