Abstract
BACKGROUND/ OBJECTIVES: Although regular breakfast consumption is associated with various health benefits, many adolescents skip this meal, particularly those with shorter sleep durations. In order to better understand the association between sleep duration and breakfast consumption among youth, we analyzed the association between weekday morning tiredness and daily breakfast consumption in adolescents, and explored the mediating role of morning tiredness in the association between sleep duration and daily breakfast consumption on weekdays. SUBJECTS/ METHODS: The "Health Behaviour in School-aged Children" survey conducted in 2018 in French-speaking Belgian schools provided data (n = 8444 11-20-year-old adolescents) on bed- and wake-up times, and on the frequency of breakfast consumption and morning tiredness on weekdays. Multivariable logistic regressions and mediation analyses assessed the association, on weekdays, of morning tiredness (≥4 school mornings a week vs. less) and sleep duration (hours), with daily breakfast consumption, and the mediating role of morning tiredness. RESULTS: Feeling tired ≥4 school mornings a week was associated with lower odds of daily breakfast consumption on weekdays (aOR = 0.77 (95% CI 0.69-0.86)). In turn, on weekdays, sleep duration was positively associated with daily breakfast consumption (aOR = 1.29 (95% CI 1.23-1.36)), even after adjustment for morning tiredness (aOR = 1.28 (95% CI 1.21-1.35)). Morning tiredness only explained 4.9% of the association between sleep duration and daily breakfast consumption. CONCLUSION: Our findings suggest that in adolescents, sleep duration and morning tiredness are independent correlates of daily breakfast consumption on weekdays.
