Sleep is an activity of great importance for maintaining the homeostasis of the human body and some components may interfere with the quality of sleep, including the pattern of food consumption. Truck drivers may constitute a population particularly sensitive to this association, since they are routinely exposed to situations that may interfere with food intake and sleep quality. Thus, this study investigated the association between self-reported food intake and sleep quality in truck drivers.
This was a cross-sectional study, with drivers who traveled in a city in southern Brazil. Food intake was evaluated through the average of food intake over the last 30 days. Food intake was evaluated in two forms: division in food groups and evaluation only tryptophan-rich foods. Sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI). In addition to the descriptive analysis, to identify possible associations between food intake and sleep quality, linear regression, crude and adjusted for confounding variables, were performed to obtain the Beta and Beta adjusted (Betaadj), respectively, and p-value.
A total of 352 truck drivers, mostly males, mean age 48.4 (±11.6) years, with a frequent consumption of meat, fruits, vegetables, sweets, and energy drinks participated in this study. The frequent consumption of dairy products (Betaadj: --0.614. p-value 0.004) and fruits (Betaadj: --0.342. p-value 0.034) was associated with lower PSQI score, while the consumption of energy drinks was associated with a higher PSQI score (Betaadj: 0.923. p-value <0.001). The frequency of consumption of tryptophan-rich foods was not associated with sleep quality.
Fruits and dairy products are associated with better subjective sleep quality, while energy drinks are associated with worse sleep quality in truck drivers, whereas dietary tryptophan-rich foods intake was not associated with sleep quality.
睡眠是维持人体稳态的一项极为重要的活动，某些因素可能会干扰睡眠质量，其中包括饮食模式。卡车司机可能是对这种关联特别敏感的人群，因为他们经常面临可能干扰食物摄入和睡眠质量的情况。因此，本研究调查了卡车司机自我报告的食物摄入量与睡眠质量之间的关联。
这是一项横断面研究，研究对象为在巴西南部一个城市行驶的司机。通过过去30天食物摄入量的平均值来评估食物摄入量。食物摄入量以两种形式进行评估：按食物类别划分以及仅评估富含色氨酸的食物。睡眠质量通过匹兹堡睡眠质量指数（PSQI）进行测量。除了描述性分析外，为了确定食物摄入量与睡眠质量之间的可能关联，进行了线性回归分析，分别对混杂变量进行了粗回归和调整回归，以获得β值和调整后的β值（βadj）以及p值。
共有352名卡车司机参与了本研究，其中大多数为男性，平均年龄48.4（±11.6）岁，他们经常食用肉类、水果、蔬菜、甜食和能量饮料。经常食用乳制品（βadj: -0.614，p值0.004）和水果（βadj: -0.342，p值0.034）与较低的PSQI得分相关，而饮用能量饮料与较高的PSQI得分相关（βadj: 0.923，p值<0.001）。富含色氨酸食物的消费频率与睡眠质量无关。
水果和乳制品与卡车司机更好的主观睡眠质量相关，而能量饮料与更差的睡眠质量相关，而饮食中富含色氨酸食物的摄入量与睡眠质量无关。
