Recent research revealed an association between chronotype and psychological constructs of eating behaviour. Here, we used food logs in adolescents and assessed their chronotype. We found that later bed and rise times were associated with the tendency to drink caffeinated drinks and eat fast food and to consume less dairy products. No relationship existed between chronotype and sweets, vegetables and salad, and meat consumption. These results suggest a healthier lifestyle in morning oriented adolescents (or late chronotypes). Breakfast times differed between weekdays and weekend while lunch and dinner times were similar. Mean breakfast time at the weekend was later in late chronotypes which was a result of later rise times of late chronotypes. The study showed that morning oriented pupils exhibit a healthier and more regular lifestyle.
最近的研究揭示了昼夜节律类型与饮食行为心理结构之间的关联。在此，我们使用了青少年的饮食记录并评估了他们的昼夜节律类型。我们发现，晚睡晚起与饮用含咖啡因饮料、吃快餐以及较少食用乳制品的倾向有关。昼夜节律类型与甜食、蔬菜和沙拉以及肉类消费之间不存在关联。这些结果表明，早起型青少年（或晚睡型昼夜节律）的生活方式更健康。工作日和周末的早餐时间不同，而午餐和晚餐时间相似。晚睡型昼夜节律的人周末的平均早餐时间较晚，这是晚睡型昼夜节律的人起床较晚的结果。该研究表明，早起型学生呈现出更健康、更规律的生活方式。
