Abstract

We investigated the influence of chronotype on eating habits among adolescents attending schools with morning (07:00 hours-12:00 hours) or afternoon (13:00 hours-18:00 hours) shifts, hypothesizing that incompatibility of study schedules may be related to dietary choices. In this cross-sectional study, 734 adolescents (aged 14-19 years) completed an online questionnaire covering eating habits, chronotype, sleep duration, social jet lag, socioeconomic data, physical activity and anthropometric measures. Odds ratios with 95% confidence intervals were estimated using adjusted logistic regression, stratified by study shift. In the morning shift, a morning chronotype was associated with higher odds of breakfast (odds ratio: 3.47; 95% confidence interval: 1.13-10.71) compared with an evening chronotype. Both morning and intermediate chronotypes were associated with higher odds of morning snack (odds ratio: 3.52; 95% confidence interval: 1.13-10.93; and odds ratio: 2.87; 95% confidence interval: 1.18-6.99) and lower odds of fast foods (odds ratio: 0.09; 95% confidence interval: 0.02-0.49; and odds ratio: 0.19; 95% confidence interval: 0.58-0.62). In the afternoon shift, a morning chronotype was associated with higher odds of breakfast (odds ratio: 5.22; 95% confidence interval: 1.85-14.72), beans (odds ratio: 3.57; 95% confidence interval: 1.19-10.74), vegetables (odds ratio: 3.52; 95% confidence interval: 1.28-9.69) and fruits (odds ratio: 4.50; 95% confidence interval: 1.55-13.07) compared with an evening chronotype. Intermediate chronotype was associated with higher odds of breakfast (odds ratio: 3.71; 95% confidence interval: 2.03-6.77), morning snacks (odds ratio: 2.45; 95% confidence interval: 1.09-5.50), vegetables (odds ratio: 1.92; 95% confidence interval: 1.03-3.58) and fruits (odds ratio: 2.50; 95% confidence interval: 1.27-4.89), and lower odds of high-energy intake post-dinner (odds ratio: 0.43; 95% confidence interval: 0.22-0.85). Adolescents with an evening chronotype had lower odds of having breakfast. Both chronotype and study shifts influenced specific food consumption habits.

期刊介绍: The Journal of Sleep Research is dedicated to basic and clinical sleep research. The Journal publishes original research papers and invited reviews in all areas of sleep research (including biological rhythms). The Journal aims to promote the exchange of ideas between basic and clinical sleep researchers coming from a wide range of backgrounds and disciplines. The Journal will achieve this by publishing papers which use multidisciplinary and novel approaches to answer important questions about sleep, as well as its disorders and the treatment thereof.
