Numerous studies have emphasized the significance of nutrition on the quality of sleep, but few have evaluated the effect of various coexisting dietary markers on middle-aged adults. We assessed the association between sleep quality and a large array of dietary markers among middle-aged, community-dwelling participants.
Data from the first, second, and third follow-ups of CoLaus|PsyCoLaus, a population-based study in Lausanne, Switzerland, was used. Sleep quality was assessed by the Pittsburgh Sleep Quality Index. Dietary intake was assessed by a validated food frequency questionnaire.
Data from 3857 (53% women, 57.2 ± 10.4 years), 2370 (52% women, 60.7 ± 9.5 years), and 1617 (52% women, 63.5 ± 9.0 years) participants from the first, second, and third follow-ups was used. Bivariate correlations showed fish, vegetables, fruit, and cheese intake to be associated with a better sleep quality (lower Pittsburgh Sleep Quality Index), while rusks, sugar, and meat intake were associated with a poorer sleep quality (higher Pittsburgh Sleep Quality Index). After multivariable adjustment, participants reporting poor sleep quality (Pittsburgh Sleep Quality Index > 5) had a lower Mediterranean diet score and a lower likelihood of complying with the meat and fish recommendations, but the results were inconsistent between surveys. No association was found between sleep quality and macro- or micronutrients in the three surveys.
No consistent associations were found between a large panel of nutritional markers and sleep quality. Components of the Mediterranean diet such as dairy, fruits, and vegetables might favor good sleep quality, while increased consumption of sugary foods or meat might favor poor sleep quality.

许多研究强调了营养对睡眠质量的重要性，但很少有研究评估各种共存饮食标志物对中年人的影响。我们评估了睡眠质量与中年、社区居民参与者之间大量饮食标志物的相关性。
使用瑞士洛桑基于人群的 CoLaus|PsyCoLaus 研究的第一、二和第三次随访的数据。睡眠质量通过匹兹堡睡眠质量指数进行评估。饮食摄入量通过经过验证的食物频率问卷进行评估。
使用来自第一、二和第三次随访的 3857 名（53%为女性，57.2±10.4 岁）、2370 名（52%为女性，60.7±9.5 岁）和 1617 名（52%为女性，63.5±9.0 岁）参与者的数据。双变量相关性表明，鱼类、蔬菜、水果和奶酪的摄入量与更好的睡眠质量（较低的匹兹堡睡眠质量指数）相关，而面包干、糖和肉的摄入量与较差的睡眠质量（较高的匹兹堡睡眠质量指数）相关。经过多变量调整后，报告睡眠质量差（匹兹堡睡眠质量指数>5）的参与者的地中海饮食评分较低，并且不太可能遵守肉类和鱼类建议，但结果在三次调查中不一致。在三次调查中，睡眠质量与宏量或微量营养素之间均未发现关联。
在大量营养标志物与睡眠质量之间未发现一致的关联。地中海饮食的成分，如乳制品、水果和蔬菜，可能有利于良好的睡眠质量，而增加含糖食物或肉类的摄入可能不利于良好的睡眠质量。
