目标：人类生物钟与营养素和食物摄入量以及饮食行为之间的关系仍有待阐明。我们对日本年轻女性的睡眠中点与这些饮食变量之间的关联进行了横断面研究。计算出的就寝时间和起床时间之间的中间点作为睡眠的中点。 方法：研究对象为来自日本 53 个机构的 3304 名 18-20 岁日本营养学女学生。通过经过验证的自我管理饮食史调查问卷评估上个月的饮食摄入量。使用自我报告的就寝时间和起床时间计算睡眠中点。结果：睡眠中点晚与蛋白质和碳水化合物的能量百分比以及胆固醇、钾、钙、镁、铁、锌、维生素 A、维生素 D、硫胺素、核黄素、维生素 B-6、叶酸、大米、蔬菜、豆类、鸡蛋、牛奶和奶制品的能量调整摄入量显着负相关。它还与酒精和脂肪的能量百分比以及面条、糖果、脂肪和油以及肉类的能量调整摄入量呈显着正相关。此外，睡眠中点较晚的受试者往往开始进餐时间更晚，进食时间更长，更频繁地不吃饭，吃饭时看电视，不仅在早餐时，而且在午餐和晚餐时也看电视。 结论：睡眠中点与年轻日本女性某些营养素和食物的膳食摄入量以及其他饮食行为显着相关。这一发现可能有助于考虑生物钟与饮食摄入和行为之间的关系。 (C) 2011 Elsevier B.V. 保留所有权利。
Objectives: How human chronotype is correlated to nutrient and food-group intakes and dietary behavior remains to be elucidated. We cross-sectionally examined the association between the midpoint of sleep and these dietary variables in young Japanese women. A calculated halfway point between bedtime and rise time was used as midpoint of sleep.Methods: The subjects were 3304 female Japanese dietetics students aged 18-20 years from 53 institutions in Japan. Dietary intake during the previous month was assessed by a validated, self-administered diet history questionnaire. The midpoint of sleep was calculated using self-reported bedtimes and rise times.Results: Late midpoint of sleep was significantly negatively associated with the percentage of energy from protein and carbohydrates, and the energy-adjusted intake of cholesterol, potassium, calcium, magnesium, iron, zinc, vitamin A, vitamin D, thiamin, riboflavin, vitamin B-6, folate, rice, vegetables, pulses, eggs, and milk and milk products. It was also significantly positively associated with the percentage of energy from alcohol and fat, and the energy-adjusted intake of noodles, confections, fat and oil, and meat. Furthermore, subjects with a later midpoint of sleep tended to begin meals later, eat for a longer time, skip meals more frequently, and watch TV at meals, not only at breakfast but also at lunch and dinner.Conclusions: The midpoint of sleep is significantly associated with dietary intake of certain nutrients and foods and other dietary behaviors in young Japanese women. This finding may contribute to consider the relationships between chronotype and dietary intakes and behaviors. (C) 2011 Elsevier B.V. All rights reserved.
