While it has long been recognized that diet is a leading behavioral risk factor for human health, recent scientific findings have also suggested that diet and sleep quality may be connected. The purpose of the present study is to evaluate the association between diet and sleep quality among a group of Spanish university students. To do so, a cross-sectional study of 868 students was carried out. Sleep quality was assessed using the Spanish version of the Pittsburgh Sleep Quality Index (PSQI), while diet was assessed using the Spanish Healthy Eating Index (SHEI). The study revealed a noteworthy rate of bad sleepers (51.6%) and students whose diet needed modifications (82.2%). Unhealthy eaters were more likely to have poor sleep quality (aOR = 4.20; CI 95%: 2.07-8.52). The unbalanced intake of vegetables (aOR = 1.63; CI 95%: 1.14-2.34), fruits (aOR = 4.08; CI 95%: 2.90-5.74), dairy products (aOR = 1.96; CI 95%: 1.41-2.72), lean meats (aOR = 1.82; CI 95%: 1.19-2.78), legumes (aOR = 1.43; CI 95%: 1.00-2.02), sweets (aOR = 1.60; CI 95%: 1.13-2.25) and sugary soft drinks (aOR = 1.46; CI 95%: 1.07-1.99) was associated with lower sleep quality.
虽然人们早就认识到饮食是人类健康的主要行为风险因素，但最近的科学发现也表明，饮食和睡眠质量可能有关联。本研究的目的是评估一组西班牙大学生饮食与睡眠质量之间的关系。为此，对 868 名学生进行了横断面研究。睡眠质量使用西班牙版匹兹堡睡眠质量指数（PSQI）进行评估，而饮食使用西班牙健康饮食指数（SHEI）进行评估。研究显示，不良睡眠者（51.6%）和需要调整饮食的学生（82.2%）的比例相当高。不良饮食习惯者更有可能睡眠质量差（aOR = 4.20；95%CI：2.07-8.52）。蔬菜（aOR = 1.63；95%CI：1.14-2.34）、水果（aOR = 4.08；95%CI：2.90-5.74）、乳制品（aOR = 1.96；95%CI：1.41-2.72）、瘦肉（aOR = 1.82；95%CI：1.19-2.78）、豆类（aOR = 1.43；95%CI：1.00-2.02）、甜食（aOR = 1.60；95%CI：1.13-2.25）和含糖软饮料（aOR = 1.46；95%CI：1.07-1.99）摄入不均衡与睡眠质量差有关。
