文献报告表明，老年人和工人的主观睡眠质量与营养摄入有关。然而，很少有研究表明青少年和年轻女性的客观睡眠质量和饮食摄入之间存在关联。我们假设，客观睡眠质量与青少年和年轻女性的饮食摄入量有关。我们评估了日本青少年和年轻女性的能量和营养摄入与客观睡眠质量之间的关系。在一项对80名年龄在18-27岁之间的女性进行的横断面研究中，使用自我管理的饮食史问卷对饮食摄入进行了评估。采用体动记录仪评估客观睡眠质量。生活方式特征，饮食习惯和心理健康进行了评估，使用特定的问卷。根据睡眠效率（SE = 85%）将受试者分为3组，并对膳食摄入量与客观睡眠质量之间的关系进行统计学评估。3组SE患者的生活方式特征、体力活动水平、饮食行为和心理健康状况无显著差异。低SE组的能量摄入显著低于中SE组（P = 0.004）和高SE组（P = 0.015）。低SE组的蛋白质摄入量显著低于高SE组（P = 0.034）。低SE组的维生素K、维生素B-2、钾、镁、铁、锌、铜和色氨酸的平均能量调整摄入量显著低于高SE组。充足的能量摄入和高质量的饮食，包括维生素、矿物质和色氨酸，可以提高睡眠质量，有助于预防睡眠问题。(C)2020爱思唯尔公司All rights reserved.
Literature reports suggest that subjective sleep quality is associated with nutrient intake in elderly people and workers. However, few studies have suggested an association between objective sleep quality and dietary intake in adolescents and young women. We hypothesized that objective sleep quality is associated with dietary intake in adolescents and young women. We evaluated the association between energy and nutrient intake and objective sleep quality in adolescents and young Japanese women. In a cross-sectional study of 80 women aged 18-27 years, dietary intake was assessed using the self-administered diet history questionnaire. Objective sleep quality was assessed by actigraphy. Lifestyle characteristics, dietary habits, and mental health were assessed using specific questionnaires. Subjects were classified into 3 groups according to sleep efficiency (SE = 85%), and the relationships between dietary intake and objective sleep quality were statistically evaluated. No significant differences occurred in lifestyle characteristics, physical activity levels, eating behavior, and mental health status among the 3 SE groups. Energy intake was significantly lower in the low-SE group than in the middle-(P = .004) and high-(P = .015) SE groups. Protein intake was significantly lower in the low-SE group than in the high-SE group (P = .034). The mean energy-adjusted intakes of vitamin K, vitamin B-2, potassium, magnesium, iron, zinc, copper, and tryptophan were significantly lower in the low-SE group than in the high-SE group. Adequate energy intake and a high-quality diet including vitamins, minerals, and tryptophan may result in high sleep quality and help prevent sleep problems. (C) 2020 Elsevier Inc.
